Network switch causing problems?

Yeah...I'll have to do that overnight tonight. Other people use this connection and interrupting it would bother them. But later tonight I'll do that, leaving it on all night. Thanks!

ps interestingly enough, here's another place with the same discussion:

Even more information, can't believe that I didn't think of this earlier:

When the network goes "out" I can still ping and connect to other computers on the network. So ping 192.168.7.15 works. I can NOT ping to an internet address via its host name OR IP address. This is appearing to be more a router problem than anything else right now. Here's the output of mii-diag:

Code:

root@pants:/home/marc# mii-diag eth0
Basic registers of MII PHY #32:  1100 782d 0000 0000 01e1 45e1 0001 0000.
 The autonegotiated capability is 01e0.
The autonegotiated media type is 100baseTx-FD.
 Basic mode control register 0x1100: Auto-negotiation enabled.
 You have link beat, and everything is working OK.
 Your link partner advertised 45e1: Flow-control 100baseTx-FD 100baseTx 10baseT-FD 10baseT, w/ 802.3X flow control.
   End of basic transceiver information.

This is the same when everything's fine and when everything's NOT fine. Suppose I'm right in the idea that it's the router?

Okay well it pretty much has to be the router. Forgot to connect directly to the router last night. Just did that, and downloading a Debian iso, the connection died after less than 5 minutes. Router reset fixed the problem, and the connection lights on the router were blinking the same way the switch lights were blinking.

So time for a new router. Thanks for all help both of you have given, and so sorry for the trouble--considering I'm a scientist, I did a rather poor job of applying the scientific method.

I guess I'm still curious why or how the router broke, but that's not as important as knowing what to fix.

Thanks again--

Sorry to drag this out, but I figured out something else today. I connected the router to my old 10MBps hub, and then connected the hub to the new switch. For some reason that keeps things happy. Maybe the router isn't "smart" enough to keep up with a 100MBps signal? Even though the communication rarely goes any higher than 400KBps...

Anyway, it all points to needing a new hub.
