This started happening after upgrading... about 2 days ago.

I have a Verizon FIOS (wireless) router... and the moment I step away from the room (approx. 20 feet away) where it is located, my wireless connection goes down...

I have pasted my syslog output below. Bottom line is it disconnects and then keeps popping up a wireless authentication dialog, fails to connect after I input the password and then eventually drops the wifi connection.

I have seen a lot of wifi issues reported with the 13.04 upgrade... appreciate your help.

Note that with 12.10, this would happen occasionally (maybe once a week) but seemed to have no correlation to distance from router... and I would reboot to fix. But with 13.04, its unusable.

I can work around this issue by using an older version of the kernel... During the upgrade, a 3.5.0-27 version was retained and I booted with that one and all seems well... –  Prashant Nayak May 3 '13 at 2:23

I had this problem on 12.10, I solved it deleting Kwalletmanager and deleting Wireless configuration allocated on Knetworkmanager, after doing this it worked very well
