6 Annoying Router Problems And Solutions

6 Annoying Router Problems And Solutions


These days, having access to wireless broadband is an absolute necessity for home offices and small businesses. And after more than a decade of innovations, you would think that the standard wireless gateway/router would be a picture-perfect product by now.

While many routers offer good features, most still come with flaws that can make life a lot harder, such as confounding setups or limited security.

What follows are six router problems that, quite frankly, I find the most annoying. I looked for possible solutions, and while I didn't find one router that adDressed all my concerns, I did discover features -- and routers -- that could make things a lot easier.

1. Difficult configuration

The problem: How long does it usually take you to set up your router? When was the last time you were able to get it right on the first try? What about when you wanted to add a new PC to your wireless network? And how about getting your wireless printer to connect to your network?

Let's face it: Each network is different, and getting the right combination of settings can be confounding. For example, even some reasonably experienced PC hands may not understand the differences between security settings or know that WPA-2 offers better protection than WEP and ordinary WPA.

These and other hitches are why setting up any router can still be vexing, even to an experienced Computer user. Some, such as the Buffalo AirStation Wireless-N 300Mbps Cable Router WHR-HP-G300N (), have crowded Menus with multiple layers that make navigation painful. Others, such as the Netgear RangeMax Dual Band Wireless-N Gigabit Router WNDR3700 (0), rely on a protected setup that has a long series of instructions that have to be followed to get a new PC on your network.

Possible solutions: Various vendors have tried to make things simpler with easy-setup CDs or one-click connection buttons, but they can't cover every possible circumstance. Buffalo's and Netgear's setup instructions go the extra mile by explicitly detailing the order in which you need to you Plug everything in before you run the CD. (Cable modems in particular should be powered on before you connect your router to them.) That's a nice touch -- but it assumes you've read the printed instructions that came with the router. When was the last time you read the manual before you Plugged in your new device?

Almost all routers have Web-based configuration screens, and as long as you remember the device's IP adDress, default username and password (which you should have changed when you set it up), you should be able to get into the setup screens and make any adjustMents you need. It's just a matter of figuring out which adjustments are necessary.

The Cisco Valet M10(0), part of Cisco's recently introduced Valet line, comes with a USB key that has the configuration software on it. Once you set up one PC on your network, you use the key to run the configuration on any other PCs or Macs (the key also includes Mac software) without having to write down the wireless encryption key or other information.

Cisco has also made it a lot easier to set up other devices, such as wireless printers, by providing a summary screen with all the relevant information about your wireless network that you can print out for easy reference when you run the setup program on the USB key.

Buffalo has a nice diagnostic routine that checks to see if you have Internet connectivity and that your router is configured properly. You run it from the Web configuration console.

Apple's AirPort Express () is simple to set up and has some neat features, including the ability to share USB printers and to share audio across the network to a connected stereo receiver. You can also extend the range of your existing AirPort base station, which is something that most Wi-Fi routers can't easily do. But if you've got a Windows PC, you've got to install Bonjour, and adding a new PC to an existing network isn't as easy as it could be.

2. Enabling file sharing from your router

The problem: Why spend money on a separate network-attached storage (NAS) unit when you can use your router for sharing files? Many routers come with USB ports to which you can connect an external USB drive for simple backup or file sharing.

Sadly, although plugging in an external drive should be as easy as -- well, as just plugging in the drive -- getting that drive set up isn't always simple. The Linksys WRT610N Wireless-N Router (0), for example, has a complex setup screen that you need to fill out when you attach a USB drive to it.

It would be nice to have software that enables the sharing without a lot of setup hassles. It should be easy to connect the Computers across your network to this shared storage, by using either the router's SSID name or IP adDress. You also need to be able to password-protect your shared drive so that it isn't open for anyone who's connected to the network.

Possible solutions: Various routers include USB ports, such as those from Linksys, Belkin and Netgear.

It's all a matter of what software is used to configure the USB drive and whether you need anything else on the Windows or Mac client end to connect to the shared drive.

Best available routers: The Belkin N+ Wireless Router (0) has a separate software configuration utility that works for both Windows and Mac systems and needs to be run only once to set up the external shared drive. After that, you can connect to the shared drive by entering its IP adDress, such as \192.168.1.1\sharename. The product isn't perfect, though: There is no way to password-protect the files on the shared drive.

The Netgear RangeMax doesn't require any additional software and can password-protect the files. It also offers a wide variety of access methods, including FTP and Web sharing, from its setup screen.

3. Performing firmware updates

The problem: Router firmware is an important first line of security defense on your network and needs to be kept up to date. But finding firmware updates on a vendor's Web site is not for everyone, and many vendors don't make it easy.

You have to bring up your browser, go to the vendor's support site and try to track down the current version for your particular router model. You then have to download the file to your PC and upload it to your router in the right place in the router's Web control panel screen.

To complicate matters, vendors often have several different versions for each router model, because they make frequent improvements to the router, often changing chip sets but keeping the version number the same.

Possible solutions: Make the update automatic or at least easily selectable, so you don't have to go through the tortured process of downloading and uploading the file.

Check the firmware update section in each router's Web setup screens to see if the router can automatically upgrade itself.

Best available routers: Belkin's N+ Wireless and Netgear's RangeMax both have a menu-selectable software switch to enable the updates. Once this is set, you can forget about it and be confident that you will always have the latest firmware.

4. Enabling temporary wireless access

The problem: If you have visitors or needy neighbors, do you really want them to have permanent access to your enTire network? Even if you trust them on your network, do you know how good their own security is? (For example, will your neighbor's notebook end up in the hands of his teenager?) If you simply give a visitor your router password, then you probably need to change this information when he leaves your home or office -- which is a real pain.

Possible solutions: A good idea would be to grant them temporary guest access that gives them just an Internet connection and nothing else on your network, such as shared drives or printers.

Vendors have begun to enable this on their routers in a variety of ways. Belkin, for example, has an option it calls "Hotel-style," meaning that users are directed to a Web landing page where they enter a special guest password. Other vendors make it easy to set up separate wireless networks just for guests. (If you use Apple's AirPort Express, on the other hand, you're out of luck -- there isn't any guest access.)

Best available routers: The USB key that you can create with Cisco's Valet can help here as well. You need to run an automated setup routine from the USB key (rather than from the Web UI) on each of your guest Computers. Once you do, it will set up a separate wireless network with a different name and password that only allows Internet access.

5. Determining who is on your wireless network

The problem: Just because you think your network is secure doesn't mean that it is. It's probably a good idea to regularly check to see who is using your router -- especially if you haven't changed your router's default password. However, in a world where it's hard enough to remember to back up your Computer, it's unlikely that most of us have the time or inclination to regularly check who has been on our networks.

And even if we want to, it's not always easy. Typically, most router Web UIs indicate who is currently connected, but finding this out requires digging through many menus. Sometimes the vendors hide this information under a title like "DHCP client list" and/or give you just the IP addresses and host names of current connections.

Wouldn't it be helpful if your router notified you every time someone connected? Even better, how about a historical view that shows you when and who connected to your network over the last week?

Possible solutions: There are lots of enterprise-class wireless monitoring tools, such as AirMagnet but, price-wise, these are typically out of the reach of home and SMB users.

Check out the screens that are usually labeled "Attached devices" or "DHCP client list" to see who is connected and using which IP addresses. Some companies, such as Buffalo, clearly show how various clients have connected and what wireless devices they are using.

Best available routers: When Cisco bought the company Pure Networks, it acquired a piece of software called Network Magic. The Windows version of Network Magic will show you a pretty map along with a more useful network histogram timeline revealing who has connected when.

For some reason, Cisco includes this software in some of its Linksys routers but not the Valet M10 series. You can purchase a license for up to three PCs for that will work with any router. (The Mac version doesn't have the maps or histograms.

6. Changing your DNS provider

The problem: After you've set up your network, you probably don't give your Domain Name System settings any further thought. If you have a cable or DSL modem, you hook it up and it automatically gets its DNS settings from the cable or phone company's DNS servers. (If you're running a large enterprise network, typically you have your own internal DNS server to provide this service.)

Home and small-business users may want to look into finding an alternative DNS provider. Why bother? Two good reasons: better browsing performance and better security against known phishing and malware-infected domains. (Your actual performance will vary widely, depending on your Internet provider and, if you are using a cable modem, how congested your cable line is.)

Possible solutions: Individuals and smaller businesses now have several alternative providers that are worth considering, including OpenDNS and Google Public DNS, among others.

Getting your router vendor to support these servers is sometimes tricky. A few routers, such as 2Wire's Home Portal 3000 series that comes when you order service from AT&T U-verse, don't even support alternative DNS settings. Making matters more difficult, most of the automated setup routines that routers include don't allow you to enter your own DNS provider.

So if you've decided to go with an alternative, first make sure your router supports alternative DNS settings. If you're not sure, see if you can enter your own DNS address on your router's Web-based setup screens instead of just using what your Internet provider gives you.

Then try it out, including installing its software to optimize your individual PC, before messing with any of your router's settings. After you make the change to your DNS, there is a Java tool that can test your speed to see if it makes a difference. Depending on how you're connected to your Internet provider, it can help either a lot or not much at all. If it doesn't help, consider going back to your original settings.

Common Problems With Wireless Routers

Common Problems With Wireless Routers


The internet is so important and well integrated into people's lives that going without it is unthinkable. This is why wireless router problems are some of the most frustrating Computer problems around. This article discusses some of the more common wireless problems and should enable you to get up and running as quickly as possible

Do I need a special code to connect my wireless router to a Time Warner modem?

Not at all. There is no special "code" that I'm aware of. All modern cable modems are Plug and play (PnP) straight from the box and programmed to work with all modern broadband routers. You'll probably have to tweak a couple of settings on your router for optimal performance but that should be it.

How do I reset my router?

The best way is to hold down the reset button for 15 seconds with the power on, which should cause all the lights to flash thus indicating a reset. Sometimes this button is really small so you might to use a sharp pencil.

Can wireless routers cause problems with a digital TV antenna?

Digital TVs and WiFi bands are on very different bands (~450MHz - 650MHz) vs (2.4GHz or 5.0GHz for WiFi) so they should not interfere with one and other. That said, if the wireless router is close to the TV antenna then it could overload the digital TV and cause your TV reception to go all fuzzy. To be sure, move them 10 feet apart this should sort the problem.

In my wireless router settings I have a noise (dB) rating. What is this and when does it become a problem?

This refers to the amount of interference when your wireless signal is transmitted from your router to your Computer. The lower this figure is the better. Ideally, all noise levels should be 0dB but that is never going to happen. A router can broadcast a signal with up 70dB of noise and still perform without a problem.

Noise can be causes by electromagnetic fields in close proximity to the router. One way of lowering this is to disconnect all the ringer wires from your telephone sockets, breaking the electromagnetic field they create. Modem telephones don't' require the ringer line to be connected to ring so this won't affect the phone at all.

Problems With Wireless Routers

Problems With Wireless Routers


Our company is a Fast and reliable Internet. While the Wi-Fi router to provide a great service, there are problems that may occur. With a bit 'of knowledge, we know what to look for and how to solve these problems.

Slow connection may be a popular concern. Make sure you know where this problem originated before it comes to taking on the router. If this is the ultimate source, there are some things you can do.

Intimidatoryas it may be, updating your firmware may speed up your connection. There are many places online that will give you an easy guide on what to do. Another reason for slow connection can be a bandwidth overload. This may be caused by larger electronics in your home. Try unPlugging them to see if it speeds things up.

Gamers find problems with poor connections as well. The most common solution for this is a new router or adapter made specifically for gaming. If you still have problems, you might just need to find a quicker internet service.

Forgetting the password to your device can be really frustrating. Luckily, there is an easy fix. On the back of your device there should be a small depressed button. This will reset it back to its default settings. Your manual should have more information about this. If you lost your manual you can call the company and they can guide you through the process.

Some people are concerned with the amount of electricity the router uses. It runs all day and night and sometimes this may seem wasteful. While it doesn't require much energy, you can purchase an energy saving device to help with this.

One problem that is pretty tough to resolve is a dead spot in your home. A dead spot is anywhere that the internet has little or no connection. This may also be a problem with your internet service but may be an indication of a bad router. The most recent versions (802.11n) may be the fix you are looking for.

While some problems can't be helped, many require simple and cheap solutions. Understanding how your wireless network works can help you when these problems arise. This gives you a basic knowledge of these common problems and how they can be fixed.

Have You Had Problems Setting Up A Wireless Router?

Have You Had Problems Setting Up A Wireless Router?


A friend contacted me with a network problem the other day that
I thought I'd share with you. Perhaps you have experienced as
well. And you know the definition of or experience?
Enjoy what you get when you do not do what you want!

My friend and his wife had gone wireless. They bought new laptops
with built-in wireless (Wi-Fi) and I wanted to start to wander
The Place of Home LAN cable during the untetheredInternet.

So in addition to the laptops they came home with a LinkSys wireless
router to provide the necessary access point for the laptops.
The guy at the Computer store said it would work like a charm.
All they had to do was Plug in the wireless router and go.
After rebooting, powering off and on, and calling the Computer store
all with no success, they figured they had nothing to lose by calling me.
I haven't figured out whether I'm flattered or insulted.

Nonetheless, I was able to help because I had experience (see definition above).

Let's start with a little background. As you probably know, to send and receive information
on the Internet, your Computer has to have an Internet Protocol (IP) adDress.
This IP adDress is a part of the Internet's Transmission Control Protocol (TCP).
These addresses, which uniquely identify devices on the Internet,
are given out in blocks to Internet Service Providers (ISPs)
by the Internet Assigned Numbers Authority (IANA).
Your ISP then redistributes these addresses to its customers. You, in other words!
I haven't heard of any ISP that gives out multiple IP addresses per account.
Usually if you have one digital subscriber line (DSL) or one cable-TV Internet connection you get
one IP address. And even then, the IP is frequently not permanently assigned to you.
The ISP will let you use it while you're online and then give it to someone
else when you disconnect (i.e. turn off your DSL or cable modem). This process
is called Dynamic Host Configuration Protocol (DHCP). Remember this DHCP.
It will show up later!

So how is it that at your home you've been able to have more than one Computer
with only one IP address?

Well two things come into play.
First the IANA has reserved the
following three blocks of the IP address space for private internets:

10.0.0.0 - 10.255.255.255 (10/8 prefix)
172.16.0.0 - 172.31.255.255 (172.16/12 prefix)
192.168.0.0 - 192.168.255.255 (192.168/16 prefix)

Secondly there's another protocol called Network Address Translation (NAT) involved.
The private IP address Mentioned can be used freely and the Internet system
should ignore any those addresses if they wander out on the information superhighway.

But your local router listens for those addresses. And if there are any packets, as they're
sometimes called, with a private (or internal) IP address headed out onto the Internet,
your router will substitute its own IP address that it acquired from your ISP
(this is the Network Address Translation).
When information returns your router will get it first and keep track of where to
send it back to you via your private (or internal) IP address.
Your router is able to do this even if you have multiple computers on your
private (or internal) network.

Now, getting back to our problem. You may have noticed that your wired PC gets one of
these NAT private addresses such as 192.168.1.100 when you turn it on. Routers
request a real address from your ISP (many times via DHCP). And then your
router may give you an private IP address via its own DHCP server. When it gives you
the IP address it also tells you to send your packets to it first. It becomes
your gateway so that it can translate the internal private IP address to the real
IP address. So the gateway IP address many (but not all) routers choose by default is 192.168.1.1
and especially LinkSys routers.

But here's what happened to my friend. They already had a wired router (a Netopia) that
was getting a real Internet address and using a private internal gateway IP address of
192.168.1.1 for the computers on the wired network. When the new LinkSys wireless router
was Plugged into the Netopia, it asked for an IP address via DHCP. It was give an IP address of 192.168.1.114
by the Netopia. And then the LinkSys set itself up as gateway IP address 192.168.1.1 for the wireless
PCs that connected. Now you might think this would work since there were two separate private
networks in fact. But as it turns out, routers are pretty smart, but apparently not that
smart. The LinkSys wireless router received outbound packets at gateway IP address 192.168.1.1 but
got mixed up trying to forward them onto the Netopia router which also had a gateway
IP address of 192.168.1.1 that it was using.

The solution? Using the LinkSys browser-based configuration utility I changed the default gateway IP
address to 192.168.2.1 for the LinkSys.

Now I ignored some IP addressing issues such as subnets and masks.
So if you're looking for more information or more details, try searching for
"IP addressing", "private IP network", "NAT protocol",
or "DHCP".

I hope my experience saves you from getting some experience!

Problems connecting two wireless routers in the same house

Problems connecting two wireless routers in the same house


If you have a big house or office that requires you to connect to the Internet more than a warehouse far away, you may need to connect the wireless router to distribute the connection. This happened to me recently when I wanted to access a clear connection to the internet in my garage. Connect two wireless router was the only solution for me.

We all know that just Plug in both your router and start using them, but soonwill discover that problems between the two wireless routers.

One of the main problems that I noticed when you use two routers in the same house is that you must activate the connections when you move from one end of the house to another. This annoyed me no end, as I go around like my laptop. I want to be in the middle of something and realized that my connection was down and tried to connect to another network. Sometimes I wouldhalf would be in line editing and all my updates lost something because of the exchange between the two wireless routers.

If this problem occurred, it would also change my IP adDress, which could also cause problems when trying to share files or connect to other remote desktop Computer. I really need to clarify how to use more than one wireless router in the same house.

It was pure laziness that I had put in this situation becausetwo wireless routers do not work really hard. It was just a matter of taking the time and effort to ensure that the two routers should work well together.

I had two options when you connect two wireless routers in the same house:

1 One was to connect the two wireless router with client mode. This method is not so great because it can reduce the speed of internet connection. A further declinethis method is that the further away the player receives the second router, the worse the connection. I made a different choice, trying to solve my problem.

2 The next option was to connect the two routers with bridging. This method is a little 'complicated, but it works better and also not to reduce the speed of your Internet connection. It can be a little 'technical, but I think with some good instructions to do any work like that. Solve the problemis not difficult, you just have to figure out how to do it.
