I just read something on one of the AT&T forums that there could be an issue if you get assigned an IP address in a particular subnet. The person stated that as long as he was in the 17x.x.x.x subnet, the Microcell would never connect, but if his IP address got renewed in the 74.x.x.x subnet, it magically worked with no changes to his FIOS router.
Anybody from Verizon care to chime in on this?
I'm not sure if this forum allows hyperlinks, but I'll try and post the link with this discussion below:
