It is in bridged mode.  I have it connected to a netgear router.  The problem I described happens whether or not I use the router.   I plugged the modem directly into both computers one at a time and still the problem persists.

Is it an integrated router in the modem?  They tend to suck - might be exhausting connection limits or something (bittorents?).  I'd say set the modem to "bridge" if so and use/try a 3rd party router.

Another thing is it sounds like you're triggering something like a policer that at a high mark "penalizes" you and reduces your cir temporarily.  Network Quality of Service boxes like Sandvine deep-packet inspection (dpi) appliances were known to do this as a policy (abuse), and most isp's have and/or use something like them.  This is almost defacto in 3g/4g cell networks.

No one will flat out admit to it really in a non-cell network that "unlimited" bandwidth is advertised and perceived, but even Cox had them installed and ready to turn on until the backlash against Comcast for using Sandvine's stopped them.

My guess is your DSL modem is rebooting; how old is it?
