I am running Linux Mint Cinnamon 17.1 (Rebecca, kernel 3.13.0-37-generic) and using a Rosewill rnwd-n150 USB wifi dongle (chipset RAlink rt5780 or rt2870]. Under windows 7 on the same machine the device worked flawlessly. Now the device works great sometimes, or will say it's connected with about 80% signal strength but I have no internet access, will frequently disconnect, or just refuse to connect altogether. I am using USB tethering from my cell phone over wifi right now.

I assume it's a driver issue, other threads have said the rt2800usb driver supplied with the kernel do not always work with every version of this chipset. I've got build-essential and linux-headers-generic installed. I unpacked the driver's tar file and changed "n" to "y" in the config.mk file:

# Support Wpa_Supplicant
HAS_WPA_SUPPLICANT=y

# Support Native WpaSupplicant for Network Maganger
HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y

Here's some basic info, then I'll post the errors I'm getting when I try to use the make command. I am a complete newbie, BTW. Thanks for any help you can provide!

Error 1 is permissions; Are you building as root? If not, you probably need to.
Error 2 is 'file not found' presumably as a result of the error 1 above.


HTH

It seems that the driver you're installing is not compatible with your new kernel. You should try this :
Just let me know if works
