PCI-E intel 5300 wireless doesn't work. Then the USB wireless adapter

[michaelgn]

Dear all,

I thought I have met this problem before before my two wireless adapters both stopped working.

PCI-E INTEL 5300
TP-LINK WN821N

My case is a little different from those I found on this forum.

1. When I upgraded my thinkpad x200 to win7 64bit, I don't have "Wireless Network Connection", but I fixed it by stopping one setting of Kaspersky and it came back, so when I first found my PCI-E wireless didn't work, I thought the same thing happened, although I didn't remember the details, I tried the Kaspersky, don't work.

2. I updated the drivers, uninstall-install, start-stop-start WLAN AutoConfig... I have done a lot that can be searched on line, never worked for me.

3. Tragedy happened, I adjusted several common options on BIOS, then after several tries I made to make 5300 work, USB wireless died Don't know how to recover it, and back to my laptop again.

Could anyone here help me out? Really appreciate it! I have spent two days on this stuff, if no one can do this, I guess the only way is to reinstall the OS, that's the least thing I want to do.

Thanks!!!!!!!!!!!!

PS: Unavailable wireless adapters have all zero Mac addresses, also can't be found in control panel.
