WiFi drops when the phone rings

My wifi dies when my wireline phone rings. But only occasionally. It takes about 10 minutes for the wifi to return. The router shows that the wifi is working. I switched to FiOS Quantum a few months ago.

If your "wireline" phone has a cordless handset it's probably channel interference.

Try changing the channel the router is using for wifi.

Just an extra note:

Cordless phones which are stated to be "DECT 6.0" operate on the 5Ghz Range. Other phones also operate on 2.4Ghz, and will usually say that they do.

In almost all cases, these phones will bounce between all channels on 2.4Ghz or 5Ghz (again depending on the handset) in rapid succession. Your router could be viewing this as interference and shutting down the radio until it thinks it is clear. This should hold true especially if the phone is very close to your router. Sometimes a way around this is to force the router to not use Auto Channel Detection, but to instead stay locked to a channel at all times.

Smith6612....DECT 6.0 phones operate on 1.9 GHz and thus shouldn't interfere with wifi.

Cordless phones used to operate on 2.4 GHz but man, I haven't seen one of those in a long time.

If the OP does indeed have a cordless phone they should definitely check to see what frequency it uses.  But I think it would have to be pretty ancient for it to be on 2.4 gigs.
