I have installed drivers for RaLink 3290 of my HP 2000 notebook using following link How do I get a Ralink RT3290 wireless card working? That successfully installed and made it to work. My notebook able to detect wifi and connects to it successfully. But suddenly while using wireless, OS crashes and displays kernal crash error message. I have tried browsing around there are questions about this but found no solution. I also tried using Linux Mint LMDE as well which has got same issue. Here is the image of the crash.
I found even broadcom drivers had same issue here. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1181392 They solved it using b43-Ippy drivers which i guess are for broadcom chipset only.
