Windows 7: Win 7 unable to connect to wireless network(router)

Win 7 unable to connect to wireless network(router)

Hi all,
i have some problem with my wireless connectivity,
When i try to connect to a wireless network, it keep saying "Unable to Connect to X" (let's assume the network name is X)

When using network troubleshooter,
it recommend me to turn off the router, keep it for 10 secs, and turn it back on,
i've done so, but the problem still there
and then the troubleshooter say there're some problem on the access point or the network adapter (Intel WiFi Link 5100 AGN)

but it seems no problem with other networks and all laptops except this S57B works fine..

and the strangest of all is: somtimes it works fine, and sometimes disconnected + unable to connect.

What possibly causing the problem?

Additional Info:
BenQ Joybook S57B
OS: Win 7 Ultimate x86 (Upgrade ver. from Vista Home)
Network Security Type is WEP

Thx in advance

I have had trouble adding a separate cisco switch and a wireless router onto the comcast cable router. I have the phone and internet. After running a PING test I saw the speed was significantly slowed down by 1/4 due to the netgear wireless router. So I unplugged that and bought a non-wireless cisco router that did not slow the speed down. Now I need a wireless router as my wife bought a Ipodtouch. Don't waist your money on one of these, get the real ipod phone! Just a note! These are worthless if you can't get online! Only good for photo's, Music, and videos downloaded onto it. Back to the wireless network problem. The main router needs to have multiple ports or the DNS will not work. I am guessing you are running more then 1 router inline.

WEP security doesn't always work out so well with Windows 7. You would better off using WPA2 and AES encryption "assuming you have these options". You will want to change this setting in the routers set up page and also go back through your Windows 7 wireless set up and change the settings.


After that try running this Xirrus wi-fi scanner and make sure you are using an unused channel for your wireless connection. You can change channels in the routers wireless settings.
