I'm having a problem with my Fios 100/100 service.
Upload speed degrades over time resulting in 100/10.
This is a new problem.
Resetting the router restores full speed.
My computers are wired to the router.
Upload speed is vital working from home.

Speed that degrades over time can be symptomatic of a cabling issue. Can all patch cords and connections be checked in particular the one between the ONT and router. If known good spares are available, can working cords be swapped out?
In addition to cabling, how is the cooling/ventilation for your ONT and router? Make sure there is plenty of airflow for both devices.
If you're running a third party router, check to see if you have QoS enabled. Turn it off OR make sure it isn't on "automatic" mode where the upload speed is being progressively lowered.
