comcast business service

A while ago I got Comcast's business service. Semi-idle connections
are get dropped (I haven't really diagnosed this - I just no that it
isn't the client or server but some network in between). However the
second and most obvious issue is that intermittently, the service will
grind to a halt:
--- 8.8.8.8 ping statistics ---
37 packets transmitted, 34 received, 8% packet loss, time 36263ms
rtt min/avg/max/mdev = 398.821/5989.160/14407.055/3808.068 ms, pipe 15

After a modem reboot, it goes normal:
--- 8.8.8.8 ping statistics ---
4 packets transmitted, 4 received, 0% packet loss, time 3003ms
rtt min/avg/max/mdev = 23.181/23.920/24.298/0.474 ms

This seems to happen about once or twice a day. I can't attribute it
to any type of traffic or number of connections. All of the rest of
the network equipment is the same and the behavior persists when a
computer is plugged directly into the modem. I called Comcast and they
said they didn't see anything even when I was experiencing ridiculous
ping times. I tend to think it's an issue with the 'modem' but I'm not
sure what the issue might be or how to reproduce it when asked to if I
tell them to look at it.
