Bug Description
I have a Dell XPS15 L502X laptop with an Intel Centrino Wireless-N 1030 network card. I'm trying to use the Wi-Fi at "n" speed at 150Mbps or more but I haven't been able to achieve it.
In 10.04 there was a bug that is now considered "SOLVED" in http://
I can see that the iwlagn module is not enabling the n channel even that the iwconfig command report it as available because in dmesg the only channels reported are the a b and g channels. The max bit rate that the card can achieve is 54 Mb/s

Similar problem in connection with suspend / resume that causes this card/driver not to function at all.
My ubuntu 11.10 64bit, 3.0.0-16 kernel on Dell XPS L502x has strange problem with integrated Intel Wireless card (Intel(R) Centrino(R) Wireless-N 1030 BGN, REV=0xB0) or iwlagn drivers. After suspend and resume network does not work on some routers. It works with old Fonera (serving b/g) but not with TP-Link TL-MR3420 (serving b/g/n or even b/g only with n disabled).
Trying to solve the iwlagn problem:
* rmmod / modprobe does not help
* reboot does not help
* syslog displays that I get IP address but then starts displaying errors Aggregation not enabled for tid 0 because load = ... see below; (these errors are not always displayed with this error condition, but never, when wifi works)
NB! Only thing that helps is booting to Windows (lucky me - kept the partition), using network, and booting back to Ubuntu.
