Troubleshooting
If you are experiencing problems with the connection (unable to connect, low signal strength, slow connection speed, not working, unstable wireless connection) you may want to tune your router’s signal by changing the frequency (if your router supports 5 GHz) and channels on the router. You do not need to change the frequency or channel on the Adapter; it will automatically pick up the new settings after you reboot the router.
For instructions on changing channels, refer to the documentation that comes with the router.
