View Full Version : [ubuntu] Lenovo T61 with Intel 4965AGN WiFi extremely slow wireless speeds

May 15th, 2008, 09:57 AM
Running under Hardy 8.04 with the iwlwifi driver on a Lenovo/Thinkpad T61 is slow. On various networks, my upload & download speed tends to max out at 18-kbytes and 30-kbytes per second.

Does anyone have ideas on how to debug this?

Bump. I also have this issue. Using an older Linksys Wireless B router. I forget the model type. I will try to reply with that later.

Wireless speeds are extremely slow and DNS resolution also seems to be shaky.

(I'm a systems engineer and it's baffling me)

I had the same problem and have a T61. I simply changed the channel of the wireless router from 2 to 9. It works great now.
