I switched to VZ 5G home internet approx. 2 months ago from Xfinity.. The problem is , can't send email before 5PM with outlook on three different Windows machines. At 5PM my outbox empties and I can send with no problem. I have Comcast and Gmail addresses. Both fail with sever interruption and/or auth failure. 5 service calls to VZ and they keep resetting the Gateway, both soft and factory along with refreshing the network which fixes temporarily. If I go to my Cellphone hotspot for internet all works fine all the time. The specific key here is, somewhere someone knows what 5PM in the afternoon is doing out there. 14 yrs. with Comcast, no problem.
