Verizon Fios router (Swarthmore)
G1100 router, removed from our system 2 years ago when we moved to new ONT. Verizon did not ask for it back. I do not know how Verizon authenticates these so I cannot guarantee it will work with new or existing service, but it was rock solid for several years before we replaced it.
