Extender needs frequent rebooting

I still haven't called yet. I have a computer used as a media machine that only sees occasional use and was the first to start having issues with this router. I recently unplugged it to see it perhaps it was contributing to the issue. I still have problems and need to reboot the router once or twice/week, but it's better than every 12 hours.

Still need to contact tech support... Just need to find the time.
