I just recently signed up for FIOS internet and having intermittent connection problems. It seems to occur mostly in the mid afternoon and my internet connection will suddenly go out, though FIOS tv is still working.
Resetting the router doesnt seem to work. The only thing that does is unplugging the wall unit and battery (the one connected to the outside box). That will bring back the connection and sometimes it will stay, sometimes I have to do the same thing a few minutes later.
I had read that I might be having these problems since my neighbor also has FIOS, but unsure how to resolve the issue.
