My router over night stopped being able to hold signal. I've checked cords, turned off and on and pushed factory reset. My xfinity internet is still working with my TV.

A little more details are needed. 

Go into more details on "won't hold signal"

You mean the wifi is broadcasting but devices are saying "connected, no internet"

Is the wifi not broadcasting at all? 

Is it broadcasting but devices won't connect? 

Do wired devices work?

What modem/gateway is it connected to? 

What firmware is on the router? 

[StormieElaine]

Its connected to xfinity box. When I try to use the wifi on my phone it blinks signal several times then has an exclamation next to signal sign. On my laptop the signal turns to the globe meaning not connected.

what "xfinity box"? a model number helps. 

If you hardwire a device into the router, does it work?

That router is a bit aged, might be time to upgrade. If after resetting or power cycling it doesn't fix the issue might be time to get something new.
