I'm sure this is probably a coincidence, but as I said, my internet seemed
to slow down at certain times of day around the same time as the new
neighbors moved in.  Who knows, 8 new people could've added Comcast
internet in my immediate area as well, so not sure.  It was just an
observation.

The modem I am using was provided by Comcast.  I also use their phone
service so their modem was required.  I am not sure if it is a DOCSIS 2 or
3 and I cannot get into it from work as I am VPN'd in and don't know it's
IP address.  I'll probably have to plug straight into it and get a DHCP
address from it to determine if it has any status page with diagnostic info.

Outside of certain times, my internet is pretty flawless.  I wasn't trying
to insinuate that there was some sort of issue with my signal that was
causing problems with my internet because it always works; it's just slower
sometimes than others (which makes sense on a cable connection, just is
more pronounced now).  I also have absolutely zero problems with either of
my TVs that are connected to Comcast set top boxes.  This is really what
threw me off considering the HDHR Prime is the only device that is having
any issues whatsoever with my signal and this initially led me to believe
that this may not be my issue.  Now, I'm not so sure.
