New Intel WIFI Link Driver Randomly cut off Internet Connection

2010-04-13, 4:52 AM

Two day ago I used ThinkVantage SYstem Update and installed Intel Wifi link driver (ver 13.01.1000). But since then my computer was randomly cut off internet connection, and the wireless signal strength icon on the system tray indicated no nearby wireless network. And then it powered off the wireless connection. Whatever I do, I cannot re-power on the wireless (I used Access Connection to power on the 802.11 wireless radio, but it could not be turned on and nothing happened) unless I restart the computer. 


I thought it might be the router that malfunctioned as this problem never happened before. But after I checked the router and used another notebook to test wireless connection, I was sure the router ran very well.
Then I re-installed the TVT Access Connection (ver 5.61) and the Intel WIFI Link Driver (ver 13.01.1000) but the problem remained. Could anybody give a possible solution? 

 

I also noticed on Lenovo's website, the Intel wireless card driver for T61 is v13.00.0000 Windows Vista 23 Oct 2009. It's lower than what I have now. Could that be the cause?

 

My ThinkPad T61 has the following configuration:

Model: T61 8897CTO

OS: WinVista Home Basic SP2 32bit

Language: EN

Wireless Card: Intel 3945 ABG

Wireless Card Driver: 13.1.1.1 (previous one was 13.0.0.0)

TVT Access Connection: 5.61

Solved! See the solution

Hi carlven,


Anytime when wireless driver is updated, Access Connections also needs to be reistalled.


Do this, first uninstall your wireless driver and access connections, thereafter reboot your system. Then install wireless driver first, again reboot, subsequently install access connections, reboot again.


When installing any lenovo driver manually, keep in mind they first extract themselves to a default location in C:\Drivers..., second .exe setup must be run from that location to successfully install the drivers.


Hope it helps.

I was having the same problem on my T61.  I rolled back the driver to the one release in March'09, and took Access Connections out of the startup list.  That also fixed it.  Just wondering what advantage it is to have both the latest driver and the latest Access Connections on my laptop that was purchased in October 2007.

I went ahead and took the suggestion about uninstalling the driver and Access Connections, then reinstalling.  It took several hours to get through all of it, but it seems to be working fine now.  Haven't had the problem with the radio shutting off for a couple of days.  It was happening several times a day before the fix.

I didn't see any advantages to have the latest device driver and access connection, except for some hotfix for software defects.

 

The point is, on each of the Lenovo software/driver update page, it has clearly stated that if the device/software was running perfectly, it might not be necessary to update it or install the latest version. Also, if you use TVT System Update, the new software/driver always appears in the 'Optional' category, which means you have the options to install or ignore it.

 

My T61 was also bought in Oct. 2007 and it ran into a serious problem in April 2008 and I rolled it back to factory setting and since then I never got any problems.
