It started happening last night and my laptop started to connect to the router, lose the connection, connect again and keep on repeating the process and hence no internet connection anymore.

Its not just my router its doing it to either.

Have tried disconnecting the wireless, rebooted, connected the wireless again (nothing worked), have tried restarting the WZC, tried a repair on the router and made sure the proxy settings are off on IE.

None of this works and it still connects for a few seconds and disconnects and then connects again. Its not the routers, they have been checked.

Anyone got any ideas on how to fix this?

Sounds like inteference.

Are you in an area where there may by lots of other Wireless LANs?
Just bought a new DECT phone?
Neighbour just bought a new DECT phone?
Baby monitor? Our baby monitor wrecked our Wireless LAN untill I moved it onto a channel away from the W-LAN.

Download NetStumbler and do a scan to see if there are other Wireless APs in the area that are using the same channel - could be as simple as your next door neighbour is running an AP/Baby Monitor on the same radio channel.

Once you get NetStumbler you will be able to choose a channel that is free (or less congested) and that will likely help enourmously.

You should be able to see the local wireless networks using the card's setup utility or windows wireless config, you shouldn't need netstumbler. None of those will help you identify non-WiFi interference on the same frequency though. Do a check for local access points and make sure there's nothing on the same channel as you, but even if there isn't it'd be worth changing the channel in case it's interference from a DECT phone etc.

Digital home cordless phone. Most are dect now.. And they can be a real pain in the arse to wireless networks. Some seem to cause more issues than others. I think Panasonics were a (un)popular offender here.
I had no end of wireless problems when a new neighbour moved in.. As it happens, they moved out not so long after, and lo and behold, my wireless network worked properly again too.
Im sure it was their phone causing it, as I had the only wireless network in the area at that point.
The symptoms were nigh on identical to what you posted too.

If the SSID is being hidden you won't, you'll need netstumbler.

It will an option on one of the Router Aministration Pages. There are usually 12 Channels to choose from (1 to 12), most routers seem to come ot of the box set on channel 6, so after determining if there are other APs in the area pick a number that isn't being used, ideally as far away from any other channels that are in use.

However, if you are in a busy area, chances are lots of people will be on 1,6 or 12, then go for 3 or 4 or 8 or 9, where ever there is less congestion.

Alternatively, if you can't find any other APs in the area then the interference is likely to be a DECT Phone/Baby monitor, so you are just going to have to try other channels until you find one that works.

Ok, where are the settings for a router?

The router was setup by an external company (my company) and delivered as a black box, just hook up and your away type of solution...

so I see no settings options or the ability to hook upto it and swap channels.

Is anything on your network on a static IP? Sounds like something is overlapping your DHCP pool.

Most routers provide a web interface which you access by pointing your web browser at the router's IP address. The 'ipconfig' command will tell you the default gateway address which is the same as the router's address unless you have something funny going on.

Is it the laptop-to-router connection thats being dropped, or is it the router-to-www connection thats being dropped ?

If its router-to-www then do you have a sky digi box plugged in to the telephone line - if so unplug - nasty little feckers those sky boxes.

It's broke. HTH biggrin

IP addresses can be assigned statically or given out by a DHCP server (your router is usually one) Normally everything gets it's IP address by DHCP in a home network but by the sound of it something has a static IP address slap bang in the middle of your address pool.

When you get the IP address conflict it'll say the conflicting address (12 digit number called the MAC address) the first few digits identify the manufacturer and will give a clue as to the conflicting device.

Alternatively just switch stuff off till it goes away hehe

Right, Janet & John guide to home networking biggrin

Computers like numbers, they really luv 'em and they can't work without 'em. But how do they get these magical numbers? You can either tell them what their number is or you can have a bloke with a bag of bingo balls giving them out when they wake up.

The bloke with the bingo balls, that's DHCP that is and it works well. Let's say he's got 100 bingo balls from number 100 to number 199. That's the DHCP range that is. Now the bingo system is infallible until a computer comes along with it's own number and the silly billy who gave it the number forgot to check which numbers are in the bingo bag banghead

What you get there is an IP conflict because the number on this naughty naughty computer has already been given out by the bingo bag man.

Now you could do some clever stuff, or you could just switch your computers off and reboot them one at a time until the problem appears then you can figure out which two have the conflict.

Is that any better? biggrin
