Solved A formerly excellent wireless connection keeps disconnecting

February 20, 2012 at 21:55:19
Specs: Windows 7, Intel Core Duo / 2GB
I have a Linksys WAG120N router which has been working fine up until about 2 weeks ago when it started disconnecting. At first it was occasionally but now it happens every minute. Things I've tried:
1/ Connecting to the router directly with a cable - it connects immediately and stays connected
2/ A different laptop - same wireless disconnections
3/ Unplugging the phone from the splitter
4/ A new splitter
5/ Shifting the router to a different jackpoint in a another room
6/ Shifting the router to a different part of the same room

The internet service provider deny any supply problems, the router company say the router is fine. I would be extremely grateful if anyone could give me some more ideas to try!

Have you already checked, whether there is the latest firmware installed onto the router?

What does the routers log show?
Does internet stay connected at routers side?

Sounds, that only your wireless gets disconnected.
Check the wireless networks in your environment and especially the channel used by those wireless networks.
You may have to change the channel, used for your wireless network.
Use +/- 5 channels to the next wireless network in your environment, e.g.:
If a wireless network in your environment uses channel 6, use either channel 1 or channel 11.

Report back.

Hi, thanks very much for your reply. Sorry but I'm not very knowledgeable about this technology - will do my best.
I did not know that routers had a log but have now discovered it on the router page. It was disabled so I have enabled it and will wait to see what it reports.

"Does internet stay connected at routers side?" Do you mean the internet light on the router? It's always on and steady.

"Check the wireless networks in your environment and especially the channel used by those wireless networks." I don't know how to check this - please could you explain?

Thanks again.

At your computer, that connects wirelessly, you should be able to get a list of wireless networks, to connect to.

There is a small freeware tool called inSSIDer2, which you can download and install.
This tools will help you, to find out, what wireless networks are in your environment and what channels are used by them.

Hi. I have downloaded the inSIDDer 2.1 software. It says Channel 11+7 but I'm not sure what that means.

The router uses 2 channels to make it possible to provide 300Mbit/s of speed.
The tool should also show other wireless networks and those do hopefulle not interfere with yours.
The other wireless networks shouldn't run on the same channel as your router do.

There is one other wireless network - must be a neighbour? It's a very weak signal and I only see it intermittently. It's always been there and never caused problems with my connection before but it does use channel 11. Could that be a problem?

Two different wireless networks, using the same channel can cause such problems.
What else has changed, right before you got this problem?
Is there a TV, near the wireless router?
Have you changed the location of the wireless router?
Is the router in the same room as your laptop?

So what has changed?

Hi Paul, thanks very much for your continued help.
The router was in a bedroom for years without a problem. I moved it to the lounge about two months ago. It worked fine in the lounge for about 6 weeks before the disconnections started to happen.There is a TV in the lounge - aproximately 6 metres from the router.
The reason that I moved the router to the lounge was because that's where I use my laptop and the signal was better. Perhaps I should have stayed with a weaker signal! I will try moving it back to the bedroom for a while and see if that helps.

Good idea.
If this works, there may be another device like power supply or microwave, near the wireless router, that disrupt the signal.

Keep us posted.

I've tried setting up the router back in the bedroom when it came from but it is still disconnecting. Actually the problem is getting worse - it rarely connects wirelessly now. Could the router be faulty?

Could be faulty, yes.
Are you sure, that the wireless is disconnecting or could it be, that the internet connection is dropping?
You can check this in the routers log.

You can also try to ping the router, when connection is lost, to make sure, that we are dealing with the right problem.

Therefore, click Start / Run and type in cmd and click ok.
At the command prompt, type in:
ping 192.168.1.1

If you get 4 replies, you didn't lose the wireless connection, but maybe the internet connection, which is a different problem.

I tried moving the router back to the bedroom where it always used to work fine. The wireless connection was there but I could not connect to it. I tried resetting the router but now there are no wireless connections available to connect to. I have to use the cable all the time now so I can't try the ping. Maybe the wireless part of the router was slowly dying and is now completely broken? It's only a year old.

Yes, when you've done a reset to it's factory default settings, all the settings are gone and you have to reconfigure the router from scratch.
That means, you also have to configure the wireless part in the router, encryption type and key a.s.o.

But maybe that solves your problem.

I've reconfigured the router now and I can see my wireless network again. I can connect to it.... but it is still randomly disconnecting so I am back where I started. So frustrating!
