Microcell not working with Xfinity
We recently moved to a new area where AT&T cell phone signal is not great (side note - AT&T does not offer high speed internet in my area either). So we got a microcell to improve the wireless signal. We have high speed internet connection from Comcast Xfinity. We have connected our own modem ARRIS SB6183 and NETGEAR AC1900 router.
I am trying to connect the MIcrocell but its not working. The GPS and status bar lights keep blinking. Tried to call AT&T customer care and tried everything
- Tried registering, re-registering the device again
- The ports (123, 443, 500, 4500) on the router have been added to "port forwarding"
- Even connected the microcell directly with modem in "priority connection" but not helping either.
Is there something else I can try or is it the Microcell is bad and ask AT&T for a replacement?? Could Xfinity be blocking something that is preventing microcell to connect or my modem is incompatible with microcell - Any suggestions??
