Linux drivers for Beceem WiMAX Chipset

It is a well known and tested fact that the Beceem
chipset for WiMAX connectivity works fine with
Windows machines. However, lately, when I tried
to get it working on a linux - Ubuntu platform
I ran into issues. As soon as I am inserting the
dongle, the machine carshes. I am using ubuntu
which has built in WiMAX drivers.

I also tried performance with the Intel 5150
chipset. However, I observed that the rate
(modulation and coding scheme - MCS) chosen
by the basestation transceiver to reach the
client fluctuated rapidly. On doing a check
I noticed that this condition persisted when
using a Windows platform. Though I am able to
get connectivity, the link does not stabalize
even when the client is immobile.
