[Ubuntu 9.04] Wireless very slow?

[zijin_cheng]

I have a fresh install of ubuntu 9.04 and i connected to my university campus wireless successfully. I know the internet is working because google page loads, but about 5-6 times slower than if i connected in vista.

I have an Intel 5100 Wireless wifi link A/G/N. My drivers are iwlagn.

I read somewhere that this works: sudo iwconfig wlan0 rate 5.5M

then editing this file: gksudo gedit /etc/rc.local and put iwconfig wlan0 rate 5.5M before exit 0

Will that work on my card?

Only one way to find out.

But it sounds plausable, and you can always undo it later on by removing that line.

it didn't work, the internet is still very slow
