Wireless stopped working, can't power on 'wireless radio
I have had this problem not being able to turn on the wireless radio for months. I have to get it turned on now. I would appreciate it if someone could help me get turn it on. I have done a number of things to try to resolve the issue.
When I press <fn> F5 I can see the wireless radio is off. I see the power on button. When I select the power on button nothing happens. I expect the wireless radio to power on.
I have tried fixing the winsock. I have run this MS fix at:
How to determine and to recover from Winsock2 corruption in Windows Server 2003, in Windows XP, and in Windows Vista
And I have run this bat file
** Start of bat file called renew-ip-reset-winsock.bat
ipconfig /release
pause
ipconfig /renew
pause
netsh winsock reset catalog
pause
netsh int ip reset reset.log
pause
** end of bat file
I have tried uninstalling , rebooting and reinstalling the wireless driver.
I have removed the following software in this order:
Power Manager Driver
Power Manager
Hotkey Utility
Wireless NIC Driver
Access Connections
I have re-installed the above software in the above sequence.
1.LenovoThinkPad Power Management Driver ver.1.62 83ku14ww.exe
2.LenovoThinkPad PowerManagerVer. 3.62 8ru410ww.exe
3.LenovoHotkey Features Integration ver. 3.52 8mvu32ww.exe
4.Lenovo ThinkPadWirelessLan11bgnVer.1.00.0029.2 6iws24ww.exe
5.LenovoAccess Connections ver. 5.84 83c755ww.exe
I have tried fixing it by re-installing the Ethernet wired driver:
6.LenovoRealtekLanDriverVer.7.7.1002.2009 80r852ww.exe
I have tried fixing the problem by making sure this registry entry was set properly.
1. regedit
2. [HKEY_LOCAL_MACHINE]\System\CurrentControlSet\Services\ndisuio
3. Change Start to "0x000000003 (3)"
4. Restart
I have installed a different hard drive and restored the Lenovo CD's. The wireless radio works fine. So I know the hardware is working fine.
I have no red exclamation marks in Device Manager. I have nothing called other in Device Manager . I have no devices with a yellow explanation mark.
The wireless device is enabled and working fine.
I have changEd the settings on Power manager .
You need to go to Globalsettings on Power manger (you can double click Battery to get there)Then you need to click on advanced settings .Under Power mangement click so it shows Disable for CPU and PCI Bus . This will not hurt computer but it will keep your computer from shutting off wirelss card to save power .You will need to restart for change to take effect . Also make sure Battery stretch is disabled . Finally
choose maximum performance as scheme name .
I have all ms updates on the machine.
The laptop is running Win7 professional sp1
3gig memory
64bit
Thinkpad Model 4444 CTO L512
Does anyone have any idea what might turn on the wireless radio?
Thanks,
