From F14 to F16: NetworkManager recognizes wireless network, but doesn't connect

Hi all,

I just upgraded a desktop 32-bit PC running Fedora 14 to Fedora 16. But after upgrading, the wireless connection which worked seamlessly before, doesn't work anymore. NetworkManager recognizes all the available wireless networks and prompts for credentials when trying to connect. But a connection is never established, and NetworkManager keeps prompting for credentials without providing any kind of error messages.

When using a wired connection everything works fine, but it is important that the wireless connection also works. My wireless adapter is a TP-Link TL-WN951N.

I tried to boot some LiveCD's with other Linux distributions or Fedora spins, including Fedora 16 KDE and Linux Mint, in order to see if I could establish a connection with one of those, but without luck. This gives me an idea that I might be missing some packages or drivers, but I'm not sure. Running iw event gives me this over and over:

wlan0 (phy #0): scan started
wlan0 (phy #0): scan finished: 2412 2417 2422 2427 2432 2437 2442 2447 2452 2457 2462 2467 2472, "Mgpf4Yfx", ""
wlan0 (phy #0): auth: timed out
with "Mgpf4Yfx" being the SSID of my network. I also tried every possible channel in my router without any luck.

Do any of you know of similar problems or can you provide some information about how to troubleshoot the problem?

Please tell if you need more information in order to help.

Try cowboys86's idea in post #4 here...
No promises. But no harm trying, either.
