Thinkpads Forum

Hi All.

My T400 can detect wireless but cannot connect. I'm running Win XP SP3, Intel 5100 Wireless, Wi-Fi card switch ON, LED light green, Device Manager shows no hardware errors or conflicts, WEP password correct. My other laptops works perfect, so this is not a router problem. Thinkpad detects the SSID of the wireless network, good connection signal, I click to connect it trys to but does not connect to the internet...

"Windows is unable to connect to the selected Network. The Network may no longer be in range"

I have tried almost everything without any sucess: drivers updates, roaming aggressivity, power output, firewall, router's settings, DNS & IP... I don't know what more can I do, please help.

Are you running the wireless drivers from the Lenovo driver matrix or the Intel driver site?

I used to have a bit of trouble with my 5300 with drivers from the Lenovo site, but it has since been remedied. Try the drivers off the Intel site, they might just work.

I tried what you suggested above. It did not work

Well, problem solved I thought that opening T400 would be a very difficult job, but it was very simple! After opening it, I found this:



I plugged that cable into the antenna jack and voilà! WiFi at last!

Oh. LOL.

How'd the wire get disconnected in the first place anyway?

Offtopic, but:
I notice you have the revised keyboard bracing. Do you have the swiss-cheese backplate? If so, does your keyboard exhibit any flex?

Colonel O'Neill, it seems that the support metal brace partially solved the problem, because the cheese-keyboard still flex on the left side, but not too much, it is acceptable in my opinion.
