PC won't stay connected to internet "Round 3" - Tech Support Forums

Sweeper · May 16th, 2006, 02:55 AM

I've posted about this before with no fix...

But now this is driving me CRAZY! My PC out of 2 others and an XBOX is the only one that won't stay connected to the internet after sitting for 2-4+ hours. I have to reboot to get back on? I have turned the power saving feature off on the software for the NIC also. I've had this problem now for some time and I tried everything "I" could think of. So, finally I figured that the onboard NIC might be failing. So I bought a new Linksys NIC. Plugged it in. Downloaded the latest drivers. NADA... SAME THING. What the heck am I missing????

What do you get if you do an IPCONFIG /ALL when this happens?

Don't know if I can help, but lets give this a shot, huh? First, I'll make the assumption that you have antivirus and antispyware protection (and hopefully firewall as well) covered, yes?
Couple questions:
Which (if any) machines are wireless, and which are not? Does your ISP assign a static or dynamic IP-and how many IPs? Do you have Dsl or Cable (or other) and what speed? Is your machine set to go into hibernate or standby? Has this always been the case with your current ISP or is this a new development? Sorry about all the questions, but a little more info would help. Heading to bed, so I'll check back tomorrow after work, but here's a couple ideas to consider:
If you run DSL, your MTU value should more than likely be 1492 (not the windows default of 1500). Probably not the culprit, but a possible performance gain nonetheless.
In your router setup, if your ailing machine is wireless, try adjusting the beacon interval setting (if available) lower than what it currently is (I usually run 50ms on my wireless network-seems to work best for me).
In both modem and router, look for QOS (quality of service) settings...giving a higher priority to the disconnecting machine may help (although it has the potential to cause connectivity problems with the other machines depending on available bandwidth and network traffic).
IMHO, creating a backup of your registry would be a good idea before any attempts at fixing anything.

None are wireless.

What part of IPCONFIG do you need to know?

Copy and paste everything IPCONFIG says.

here's a screenshot... gotta go to work... be back on this evening... once I reboot....

Well if that is from the point of failure it looks normal. That is if you have been away for more than say 4 hours (overnight) and you would not be able to use your browser.

What are you using for a Firewall, Antivirus, etc?

Sweeper · May 16th, 2006, 07:20 PM

ZoneAlarm, Norton System works 2003 ... that was while it was working. I'll post one when it goes offline again...

just had to reboot to get connected. Here is what it showed before I rebooted.

Funny.... it looks fine? But, nothing connects. No Instant Messengers, No email, No browsers (I run 3 of them) Firefox, AOL, MSN. Has to be a software issue? But where?

I'm guessing firewall, but I don't know why, since you say you have all the standby/sleep mode, etc's disabled. I recall having a similar issue with my EZ Firewall when I first set it up but right now I just can't remember what I changed. Try disabling your firewall to see if it makes any difference.
