The error message i get says "Windows can not connect to Nick ADSL (my routers name)" then i click diagnose to see the problem and it says "Windows can not connect due to the connection timing out" or something along those lines.
Hmm. Interesting. That really is the connection to the router. i.e. The wireless setup is screwed, not the internet link.
I haven't got a ready-made solution for you, but I can tell you what I'd do.
First, I'd use 2 RJ45 LAN cables to make sure that it really is the wireless thats the problem. Connect the laptops directly to the router & see if that fixes it.
Next, change the wireless channel on the router to 6 or 1 (Should be on 11 by default). Set the mode to b & g.
Also, I'd consider installing netstumbler. Its an app that can be used to check out what other networks are in the area & what channel the are on etc. Useful for figuring out if there is some clash. Note that netstumbler will take down your internet connection on the laptop until restart, so dont freak. Post screenshots if you can't interpret the info.
Finally you can try to run the wireless connection without encryption. This will eliminate encryption related issues...sometimes that gives strange issues. Do not leave it without encryption for long since its a calculated risk.
You can also try to roll-back the wireless card drivers on the laptops, but leave that for last resort.
If you like you can also post the network config of both laptops here & see if anyone spots something. You can dump them to a textfile on your Desktop by typing the following into the command prompt (Start->Run->cmd) so that we can check for issues there.
Code:
ipconfig /all > %USERPROFILE%\Desktop\IPconfig.txt
Also, does it time out 100% predictably or just most of the time?
guys im having trouble with something on my line or router or isp or something..
Go make your own bloody thread. Its rude to hijack someone else's.
