Attempt to connect to Wireless-N 5GHz network Actual results: Fails - comes back to password dialogue. Expected results: Should connect - used to work in F-16. Additional info:
Router is a Netgear WNDR3500 dual radio (2.4GHz G, 5GHz N). I can connect to 2.4GHz G, but connection _always_ fails to 5GHz N.
WNDR-3700 I mean.
What kernel version are you using? What sort of encryption are you using on your network?
Kernel version: kernel-3.4.0-1.fc17.x86_64 Network is setup to use WPA-2 (AES) encryption.
Please attach the contents of /var/log/wpa_supplicant.log and /var/log/messages from immediately after an unsuccessful connection attempt.
Thanks for pointing me at the logs. I've found the problem. My WPA-2 password is a 64-char long auto-generated random string. The last character was a "\". This was being saved incorrectly in the key-ring as a "'" character. This caused password authentication to fail. I tried manually editing it a few times in NetworkManager without success. I swapped the last 2 chars around and now I can connect. This is quite strange - I've never experienced this problem in the past (had the exact same password on Fedora-16 and it was saved correctly in the key-ring). Don't know exactly what the cause of this problem is. But as the connection works now, this issue can be closed.
>>I swapped the last 2 chars around and now I can connect. (This also meant making the exact same change to the password on the router of course...)
Closing as NOTABUG, based on documented info in comment 6 and comment 7. FWIW, I would guess that some other form of quoting/escaping would allow for the last character to be '\', but I think you current solution is as good as any. :-)
:) Thankyou for your help.
