I have a problem, I am using the Intel Centrino Wireless-N + WiMAX 6150 as wifi and wimax card but I can only use wifi. I googled a lot about drivers and stuff but I can not find the way to activate it. Before installing Ubuntu, I had Windows 7 and wimax worked properly. I don't know what the problem could be, I mean, the actual kernel version has wimax integration but it is not working on my computer, what could it be??
