problem with iwlwifi



Hi,
I was finally able to start my wifi, but soon after my first internet
request i.e. ping google.com it stopped responding. It did give result
for the first ping but there after it didnt work with constant
recursive messages in /var/log/messages

kept on repeating.

And I cannot use wifi.

How do I reset the connection? If I use NM to disable and then enable
it never re-enables, I have to restart.

any help?
