[Bug 190515] Re: [Hardy][Intrepid] Low bandwidth with rt2400 / rt2500 drivers

[Paul Moulson]

I had been using 2.3.31-17 so tried upgrading to 2.6.32 but still can't
get more than 1Mb/s through my 10Mb/s Internet connection.

@papukaija - I can believe the rt2500pci kernel module is providing
adequate support for some devices - but not certainly not for my RaLink
PCI card.

Details of my configuration below. Also more than happy to provide more
information if required.

paul at locke:~$ uname -r
2.6.32-020632-generic

paul at locke:~$ iwconfig wlan0

          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0

* Note: I have had to disable power management due to this bug: http://www.gossamer-threads.com/lists/linux/kernel/1129333
Saying that, regardless of whether I enable or disable it I still get the poor throughput.
