For the tech saavy on this thread who don't want to shell out another $400 for network gear.
A weekly reboot does the trick. I have a raspberry pi at home, and setup a script to execute on the crontab and it's worked like a charm for a month. This script will log an entry to the system log with the prefix "[orbi]" if you wanted to see any history.
Crontab Entry - I keep this script in /opt/scripts/orbi, you can store it where you like.
