It's a wep connection, it connect just for a couple of minutes, then disconnect with reason 2, here just a few lines from dmesg.

Please run the following commands one line at a time and just copy and paste for accuracy:

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

sudo modprobe -rfv rt2800pci

sudo modprobe -v rt2800pci

This command changes encryption from hardware to software and in many cases corrects the issue you are having.

Wep is not very secure and ubuntu will connect to wpa2 (AES) (CCMP) better then any other settings, not mixed mode or especially (TKIP).
