OS: Ubuntu 12.04 Kernel: 3.3.5-030305-generic-pae Device: Dell Inspiron 1464.
Recently I am having a problem that is: I use a wimax device whose chipset is Beecem BCSM250 wimax. It is ZTE AX226 wimax modem. It is working fine on ubuntu 11.04.
But in 12.04 it works good but sometimes when i just insert this modem my screen goes full black & system gets hanged. Nothing is working. So i updated my kernel from 3.2.0-24generic to 3.3.5-030305-generic-pae manually by downloading deb files.
Now in this new kernel my wlan card is not working (Chipset: BCM4312) while it was running smoothly on my previous kernel. I tried fwcutter & firmware from software centre, but it didnt worked.
Now I need both wimax & wlan working on my pc. Plz help me guys i m in a big problem.....
