CPU & Memory Slow/Erratic wireless internet

Hi everyone, this is my first post on this forum.

I have a ASUS laptop dualbooted with win7 and f16(Fedora 16). I recently shifted from Ubuntu.
Wireless internet is very slow and rather erratic on my laptop only in the case of Linux. On win7 its flawless.

I have a 30mbps connection and I have to often wait for minutes staring at my browser for a page to be found and loaded. But its erratic as in suddenly its back to its original speed and the next minute i'm in the dark.

I use my laptop at home and my college and its the same at both the places.

I recently got some help from one of the forums and added a few custom dns servers in the
Code:
/etc/resolv.conf

And there is only slight improvement. And its not only the surfing, even my email client, f16 upgrade is affected.

I have also disabled the firewall just in case. Please guys I need some help, or I might not be able to use linux properly, and as you know for a mediocre linux user a net connection is a must in order to look for answers and support for a lot of stuff..

Here is the output of iwconfig
Code:
