I've installed some newest programs through Lenovo ThinkVantage System Update and just after that my wireless connection has stopped working. Here are the installed programs:
I've got a Lenovo T61 with Windows XP SP3.
Also in Device Manager, there are now the two "Other devices" bellow with a yellow question point and a yellow exclamation point by side:
Does anyone have any idea what can be done to have these issues solved?
P.S.: when I click Fn+F5 it shows only the Bluetooth Radio.

Hello and welcome,
I've seen something like this on XP machines after updates a couple of times now - my T61, a friend's T400, and his daughter's T61. I guess that makes 3
_Maybe_ your situation is the same.
The fix in all 3 cases was to go to device manager and uninstall the wifi driver. Then scan for hardware changes and let it reinstall the driver. Something about how Access Connections or some other networking mangement thingy was hooking the drivers I guess.
On both of the friend's machines, the wired networking was also b0rked. Same fix there.

@zoltanthegypsy, thanks for your reply!
I uninstalled 'Intel(R) Wireless WiFi Link 4965AG' then I scanned for hardware changes and Windows found a new hardware and installed it. Now I click Fn+F5 and it shows '802.11 Wireless Radio' and 'Bluetooth Radio' and it used to be.
But no matter there is or not a LAN network cable connected, the application stops working and I have to go to the Windows Task Manager and do kill the 'AcFnF5.exe' process.
Moreover, when there is no LAN network cable connected and I launch the 'ThinkVantage Access Connections' application, it doesn't work neither. Then I have to go to the Windows Task Manager and do end the 'ThinkVantage Access Connections' task. On the other hand, if there is a LAN network cable connected and I run the application, it works fine.
Regarding 'Other devices' in Device Manager, now there are three:
The first one did not was part of the list before uninstalling the WiFi driver.
So, I'm still not able to use my wireless connections.
Does anyone could please help me in order to fix this problem?

I had a similar problem with a T60 after an SP3 upgrade. I posted this earlier and it may help you:
I think I may have found the fix. According to microsoft the problem can arise when winsock gets corrupted, either as part of a service pack upgrade or when NORTON is uninstalled.
The fix can be found at
on that page you will find a section titled "fix it for me" This will rewrite your winsock file. So far it seems to have worked
Cross you fingers.
You can see if this is the problem by going
and then manually start DHCP CLIENT (and if needed) WIRELESS ZERO CONFIGURATION
You should be ablre to connect then
