Cable Modem Timeout? 1

[JRB-Bldr]

I am using a 3Com cable modem connected via ethernet connection (single user, no other network) to my Win 2K Prof. PC for my Internet connection. And, in general, it works well.

But if I leave the computer un-attended for a while and return the cable modem connection no longer works. Windows 2000 Prof. seems to "see" the ethernet LAN connection since it does not report any errors. And the cable modem lights would indicate that everything is working.

But when I attempt to reach a URL or the ISP's email server, the connection fails. It is as though Windows has quit "talking" to the device.

Restarting the computer resolves the issue, but it is annoying.

1. Are there settings that I can check/change to prevent this?

2. Is that any 3rd party software to run to re-initialize the connection capability without having to re-start?

Thanks,
jrbbldr

i'm haveing the same problem but in xp, right now i don't finded an understandable reason for this problem...the only solution that i can give you is ...use de ipconfig command over "dos" enviroment and release/renew your conex without restart.

I would check the settings for power management for the lan adapter.
Found under device manager then network adapters in Win 98.
Not sure where to look in W2k but that is what I would check for.
Sounds like it may be shutting down to save power when idle you can check or uncheck a box to prevent that.

Try changing the network card. I've seen bad network cards disrupt network traffic numerous times.

I have had this happen to me with XP.
I am pretty sure the problem is caused by XP dropping the DNS servers. They appear ok when you go to ipconfig, but don't respond. I found releasing then renewing your ip fixes it.

It sounds like you need to run winipcfg or the Win 2K version to release your ip lease and then renew it.

There has been rumor that if you disable DNS Client under Services it will stop happening.

Yes! Disabling the DNS client in the Services MMC does "fix" the problem in Windows XP.

Until I disabled that service I would lose my internet connection every time my pc was left idle. It's not a problem anymore.
