I have an ATT Microcell 3g (Brand new) connected to my XB3 (DPC3939) with Xfinity. I have blast (105mbps).
My microcell drops its connection like twice a day. Green bars light on microcell flashes, phone disconnects from microcell, and reconnects after about 3 minutes. Resulting in a dropped call.
Does anyone know any specific settings for the XB3 to get them to work together more reliably?
The att forums always direct me to test my voip quality on voipqualitytest.com or something and I can never get the voip quality because it says firewall is blocking certain ports. Ive turned all of my firewalls off on the XB3 and it still happens.
ATT wifi calling can't come soon enough.
