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

[Bem Jones-Bey]

I can confirm that for me, using TKIP causes the problem. Sadly, I had
to switch back to TKIP from AES, since my router's performance with AES
is abysmal.

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.
