Please log in for more thread options This problem was strangly resolved but I have no idea why. For the last few months we have had a problem with our AT&T DSL with a Speedstream 4100 modem; the connection would go down about once a day and rebooting the modem reconnected us. We tried many things including having AT&T techs come out several times, swaping out the modem twice, changing firewall configurations, etc. Finally in an effort to troubleshoot the issue by capturing packets going to the modem I put a hub between the modem and the first switch, and by doing that the problem has been resolved, or I guess I should say we do not lose connection any more. But what the source of the problem is actually I do not know. Can anyone tell me what putting the hub in between the switch and modem would do? Could it be that the switch is bad and sending.... what kind of traffic to the modem to cause it to lose its connection? Any ideas would be appreciated. Thanks. | ||||||||||||||||||||||

Please log in for more thread options A hub will regenerate and strengthen signals. It might help poor [home-crimped] cable. -- Robert | ||||||||||||||||||||||

I was wondering if the fact that hubs run in half-duplex had anything to do with it. | ||||||||||||||||||||||

There's a very good chance your router (make and model?) doesn't deal

Which I'm seeing more and more lately with new stuff using "off the shelf" chips for 10/100 or 10/100/1000 ports. | ||||||||||||||||||||||

The device that we are using (as I mentioned) is a speedstream 4100 DSL modem, and the point is that it IS working with the hub wheras it was not working with just the switch. | ||||||||||||||||||||||
