WiFi issues

It seems in the last month, we have been having WiFi issues. I’m constantly rebooting the panoramic modem or unplugging my device to my TV for being to hot. Just got back from vacation and having issues again. We hardly use the internet, my wife works in the day and I work at night. We never have 2 people just a couple of days and we don’t use it. We go out, is there someone available to give me a call regarding this issue?
