Hi, Here is the story of my long struggle with this issue.
I have a Lenovo T520 and installed Windows 8 little over two months ago. After the upgrade I started having trouble connecting to different wireless networks ( ATT Uverse at home, Verizon Jetpack 4620LE, Verizon Pantech UML 290 and wifi networks at Starbucks). I can see the SSID but when I try to connect it, it says "verifying and connecting" and errors out. All these wireless networks work perfectly ok with rest of my devices (Windows 7 laptops, MacBook Air, Pro, Tablets etc)
However my windows 8 laptop is able to connect to the two wireless network at work, one is internal and one public wifi for guests. The only difference is our corporate wifi uses Radius servers for authentication where as rest of the wireless networks don't. Here's what I have done troubleshooting this issue so far.
1. Completely wiped the drive and reinstall the OS. Tried connecting to the wireless network with the default drivers and the same issue happened.
2. Downloaded the latest drives for the Intel Centrino Ultimate-N 6300 AGN from Intel's website and tried connecting to the wireless network. Same error again !.
3. Called Verizon to see if there was a problem on their end. Reset the two Verizon 4G cards to factory settings, updated firmware's and tried connecting. Same error.
4. Called ATT and same steps and no luck.
4. Changed Wireless Authentication Type from "WPA2" to "WPA", "WEP" and tried connecting. Same thing again.
5. Disabled Wireless security. Same error.
6. Renamed SSID.
7. Opened a support ticket with Microsoft and took Netmon logs, once while connecting to problematic wireless network and once while connecting to wifi at work, which works. And one more netmon log from Windows 7 Laptop connecting to the same wireless that has problems connecting on Windows 8 laptop. Compared the logs and all we found was there was no attempt\packet transfer while connecting from Win 8 device where as Win 7 device shows Beacon response. The log files in "C:\Windows\tracing" on Win8 device do not get updated when I try to connect to the wireless network that I have problem connecting to.
8. Called Lenovo and replaced the Wireless NIC and still have the same problem.
After all these troubleshooting I have absolutely no clue what the issue and what I am supposed to do to troubleshoot this issue. Please help if you have any suggestions.
