View Full Version : [ubuntu] Intel 4965 can't get more than 54M on Karmic

November 17th, 2009, 11:13 AM
So I had a problem with wireless not connecting so I installed the Linux backports and it started working but not going the full 130M my router can do.

I then found that there seams to be a problem with aht5k driver being blacklisted
so I removed the backport driver and tried this

1. open /etc/modprobe.d & look for "blacklist-ath_pci.conf"
2. if it is there--open the file as root & put a # in front of "blacklist ath_pci"
3. reboot

Wireless still connects but it seams the system thinks my router is only capable of transmitting up to 54M not the 130M I could get when running Windows on the same system.

This is the one thing that is hanging me up and its more of an anoyance than anything but I would still like to fix it. I like to send lots of video files over the WLAN to my NAS.
