Try:

echo "options rt2800pci nohwcrypt=1" | sudo tee /etc/modprobe.d/rt2800pci.conf > /dev/null

Reboot to test.

The module needs the option to work. The file makes the module always use that option (the actual name of the file is irrelevant provided it ends in .conf

Your wifi chip needs that option to work.
