check PC power supply also

Re: "A Network Cable is Unplugged"

Set the speed to 10Mbps. This covers and solves an amazing number of cable, switch, NIC, and NWay compatibility problems.

Do your test installs to another hard drive so if the problem turns out to not be your bloated install of Windows you can just put it back.

Re: "A Network Cable is Unplugged"

Sounds like the one thing you haven't swapped is the modem/router. Any chance you can get your ISP to send you a new one? Unlike most of the people who've chimed in to tell you to do things you've already done, I've actually read ALL of your posts. It's unlikely that you'd have this issue on only one computer connected to the modem/router, but it would definitely rule it out as source of the problem.

Also try sticking a new NIC in there and see what happens, could be some bizarre interaction with the onboard NIC chipset. Short of that, a new PSU, and the Linux live CD, you might want to get your hands on some holy water and garlic.

Re: "A Network Cable is Unplugged"

Think again.
We had our telephone line replaced a few months ago and yes, they replaced the modem/router combo while they were there.

Anyways, the last week I've been slowly notching down the speed. I'm at full duplex 10 megabit and still seeing issues. WGA also wants to re-validate because I plugged in my ipod so I'll take this window to finish the backup and reinstall clean slate from another install CD.

That's gay! That's worse than when Windows tells me to reboot, just because I connected a USB drive!

Re: "A Network Cable is Unplugged"

Go to half duplex 100Mbps. If it still does it with half duplex, do yourself a favor and put in a PCI Ethernet card. Does your motherboard have a Marvell chip for onboard ethernet? They had issues.

Still getting it after all of those? Replace caps next to PCI slots and around the onboard ethernet. I have a board that's doing it too, but i can't be arsed to care about it since it works at 10Mbps full duplex and i don't use that computer too often.

Unless you have an 8 Mb or less internet service, then it will be slower than the internet service, lol. And unless you have cat3 and/or real old switches, you don't need to drop it to 10 Mbps mode.

I hope you don't still have cat 3, lol.

Re: "A Network Cable is Unplugged"

I have half duplex on an Unix machine and it's S L O W. I can't even stream at that rate. I've been notching down from full to half and then full at the slower speed each time the connection drops.

Also, my ethernet is a Realtek RTL8169 thing. I'd totally switch to a 3com gigabit PCI card if I could find one. their cards were pretty damn bulletproof.

We're talking about a hardware fault on the motherboard here... The only thing limiting my internet speed is the switches as they're all 100Mbps. If they would be upgraded to gigabit the speed would get really silly.

10Mbps isn't all that bad, that's 3MB/sec, and that's plenty enough for all web surfing. If it works, i'm not gonna fix it.

I use 3Com cards in my router/server (running FREESCO) and they work great... When i first built it i used cheap realteks and i think i went thru 5 of 'em in 6 months. Bought the 3Coms for next to nothing and they still hold to this day, and it's been 7 years since i first built the router. It's on its 2nd computer, but i'm still using the very same ethernet cards.

Re: "A Network Cable is Unplugged"

If it's a motherboard issue I find it really weird that the problem is identical on two motherboards.

Re: "A Network Cable is Unplugged"

Typing from a laptop...

Connection dropped out and isn't coming back. Computer also vanished off the switch so the NIC isn't talking.

....yet from the back of the PC you can clearly see it's green CONNECTED light lit and the amber BUSY blinking away in no fancy order. Continues to do so with the cable unplugged.

It's done this once before. On the old board. Now I'm positive this isn't a hardware problem shared between two boards. In theory it will come back with a cold boot.

Sorry, that's incorrect! That would be only 1.28 MB/s at the most!

And because of other technical issues of the obsoleted standard, you may see it as low as 1.2 MB/s at max.

Re: "A Network Cable is Unplugged"

Yep!
Gave a cold boot and the ethernet came right back up. Something must of really locked up the chipset.

My bad, sorry.

Re: "A Network Cable is Unplugged"

I don't mean to hijack this thread, but I'd like to add that I have what appears to be an extremely similar problem. Except in my case, the router restarts *most* of the time when I get that "A Network Cable is Unplugged" message. Even more weird is the fact that sometimes the message pops up before my router restarts, and sometimes the router doesn't restart at all but I still get the message. And if that's not enough, I have also tried 2 completely different routers with 2 completely different power supplies, multiple computers connected with different ethernet cables, and I know both routers work without problem back in my parents house. So what gives? I don't know. All I know is that I am in an area with lots of military bases around, and cell-phone coverage also tends to go off every now and then for a second or two (but it doesn't coincide with the router going out). But that doesn't happen as often as my internet going out.

So I don't know what the hell is going with my stuff either, but I just wanted to throw this out here in case it turns out to be the same problem. And oh yeah - sometimes the router will restart by itself without any of my computers being on. I wonder if this could be some kind of external bot attack.

BTW, I don't know how our internet is handled since I am in a dorm complex and all we really get is just a Cat5e jack from the wall. But in any case, whatever is connected on the other side of the ethernet cable, I don't think it should be able to make my router restart.

Again, I'm not trying to solve my problem here since this is pentium's thread, but just wanted to state my observations as this could potentially be the same problem.

And if it repeats (network error), after reboot, maybe capacitors should be inspected, post your mobo model, and PSU too...

Heat?

is router wireless type?

Re: "A Network Cable is Unplugged"

After a week of frustrating trying to backup only for it to randomly crash I found that two of my sticks of RAM are bad. Either they didn't survive the VRM on the old board blowing up or that's what you get when you buy cheap unbranded ram.
Just in case for some extremely odd reason it was that glitching the chipset out I'll try load testing the system again with my remaining (and memtest passed) ram.
