Why is my fios suddenly slower this week? Nothing's changed, except we didn't upgrade to quantum gateway. So Verizon is slowing us down to force us to pay more for what we use to get?
Just to be sure, you're not testing on Wi-Fi are you? Was your plan changed on accident by someone else?
Verizon doesn't really care what router you use. If you're running an old GEN1 router like an ActionTec MI424WR REVA-D or a 9100EM, then they'll send you a new one.
