[Bug 352228] Re: Intel Wireless 5300 AGN: iwlagn: No space for Tx

[sl0n]

Looks like I've just encountered the bug for the first time. I have dell
latitude E4300 for about 3 months now and never experienced smth like
that.

I'm using D-Link DIR-635 at home and this morning I've changed  wireless
settings: "Cipher Type" from "TKIP & AES" to "TKIP" only. I believe this
action has triggered the bug. I read the thread and found some users
mentioned "TKIP/AES" problem, I changed it back to "TKIP & AES" and it's
working ok for a about an hour now.
