[Hidden-tech] Problems with Comcast connection

[REYNOLDSSM at aol.com]

Will,
I had, what sounds like, the same issue for a long period of time.  In  the 
end my issue was not Comcast, though I did use their name in vain many time  in 
the process of figuring out my issue.
 
My problem occurred when I was connected to my office through a VPN.   I have 
Macs, PC and Linux boxes all utilizing the VPN constantly, while my wife  
works through a different VPN solution at the other end of the  house.  I was 
using a Linsys router off of my Moterola Surfboard.   From my linksys I have a 
Cisco 350 wirless access point that connects my wife  and kids machines and a 
long cable to my office hub Linksys.
 
After isolating it to my linksys router, I scrapped my Linksys  router for a 
NetGear router and have had no issues since.  That  was in October.  I am not 
sure if you and your neighbor both have bad  routers, but that was my 
experience.  I hope that is helpful.

I'm  writing to check with other Comcast users in the Pioneer Valley area to
see  if you are experiencing regular connection interruptions. Both my
neighbor  and I are experiencing momentary disconnects generally every 5-10
minutes  but sometimes only several hours apart. The loss of connection is
momentary  and is quickly re-established.

I am most aware of it because I listen  to BroadwayWorldRadio.com streaming
internet radio and the stream is  interrupted and needs to be restarted. I
can demonstrate the interruption  in any application playing streaming media
- iTunes radio, Windows Media  Player, Real Player, etc.

Both my neighbor and I are using routers (I  have a D-Link DI-624, he has an
Asante) and NAT to provide access to mixed  networks of Macs and PCs. When I
connect my cable modem directly to my main  computer (G5 2.5Ghz) the dropped
connections stopped which would seem to  indicate a problem with the router.
D-Link replaced the router and we  modified settings, but to no avail. My
neighbor has not tested the direct  connection.

I think that the problem must be some sort of  connection/negotiation issue
between the router and cable modem (a Motorola  Surfboard), but I've not had
any luck diagnosing it. We've done all the  usual things such as replace
cables, reset the router and cable modem, I've  even done a "crash recovery"
on the router which completely reloads the  firmware and all settings.

Of course, from Comcast's end, everything  looks fine...

Suggestions or insights would be most  welcome.

Will Loving
