[TriLUG] OT: RR Networking Question

[Bill Vinson]

Lately I have noticed that after some period of time (10 minutes to 4 
hours) my bandwidth will just drop off.  They have a tech coming out to 
see me tomorrow, but have already freaked out b/c I don't run 
Windows :)  I originally thought I was loosing my connection and they 
had said it looked like my modem was loosing it's signal.  But, I 
noticed that tonight when it last happened I am still connected, but 
seem to be running extraordinarily slow.

I went from pinging one of the DNS server with ~ 100ms speed to anywhere 
from 500ms to 20,000ms (Typically in the 1,000 to 8,000 range).  I 
haven't figured out how to prove there is a problem as I can hook it up 
to a windows box, but it may not occur while they are in the home.  It 
doesn't seem to be the OpenBSD system as I have switched systems and 
nics and the situation still occurred (From one OBSD system, to 
installing another and using it.  I had planned on switching them out 
previously).

Anyone seen this or have any ideas?  I can't find any errors in the 
cable modem's logs and it doesn't seem likely that it is my system as 
when I power cycle the modem and restart networking everything returns 
to normal for a random amount of time...

Any suggestions would be appreciated so I am ready for the tech :)

Thanks,
Bill
