i have trouble about wireless connection with IBM T41

I have been using t41 for 10 months. Everything seemed well. I have formated my laptop serval times, about 2 times, the reason was t41 couldn't connect to wireless connection. Yesterday, I didn't know why my computer lost wireless connection eventhough I tried another lapops and they connected to internet perfectly. I used System restore, but it wasn't successful. The only possible way for me was to format my laptop again. I kept thinking that everything would be all right. After everything was done completel, I couldn't see any significance showed that t41 could connect to the internet. I could detect the net work but it couldn't detect the network name so that it couldn't access to the internet.
Another problem was after using the t41 for about 30 minutes, it doesn't respond to me anymore. I wait for it like 1h but it still there, nothing happens.
I need your helps!
Thx you so much

 

i had a t41 that acted the same way. i upgraded to an R61 a month ago. the last driver i got from intel (not lenovo) seemed to do the trick. i did a clean install of Access Connections but disable the connection portion and only used it to turn the wifi on/off with the hotkey. I used plain old Windows Zero Configuration service and it worked great. the recipient of my old machine has not complained yet so I assume he is good too. internal PCI wifi cards are cheap, so if you suspect hardware then get an upgrade. good luck.
