Windows 7: Intermittent network in Windows 7

Intermittent network in Windows 7

My brother-in-law just recently installed Windows 7 Pro 32bit on some older hardware (Pentium 4 on ASUS P4P800D-X, SIS 900 network card). At first we used the network drivers that came with the motherboard cd as Windows couldn't even find drivers for that model. That worked and then we performed update to get the latest ones... great.

The problem is, his network kinda burps along now, when it was fine with Windows XP Pro. It gets short bursts of speed and then almost like stops for a few seconds.. and goes again. I've scoured the Internet for solutions, and most came down to reinstalling the XP network drivers under Win 7. I've tried just about everything and I'm now almost certain that this network card (SIS 900) simply does not work under Windows 7 with his Speedstream 6250 DSL modem. I've tried to adjust every network setting available.. made sure firewalls weren't in the way.. no virus scanner causing trouble.

Has anyone been through this with legacy network cards and W7? I hope he doesn't need to buy a card that's compatible as it seems SIS have dropped the ball on this one.

Thanks for the help.

SIS 900 has drivers.
You just have to make them for the specific system. Post the hardware id strings and I'll make it for you.

Before we do that though, can you attach a nice screenshot of advanced tab when you go into device manager and double click on it? There's a setting there that will probably fix this right up. I need to see to be able to guess which.

I'm not at brother's house now to check the settings in advanced, but he just sent me this via email.

I can remember though when I was poking around that there was only like 3 settings in that tab.

Not much too it. Must mean there's a problem no?

Here ya go.

Right click on the network adapter in the device manager. Update driver software. Browse my computer for software. Let me pick from a list. Have disk. Browse. Now navigate to where you extracted to and double click on the .inf. Click ok the next.

So far he hasn't noticed any differences. Is there anything he should do, like say restart the computer, reboot the modem/router etc?

Thanks. At the very least, he definitely has the right drivers installed.

Could try a reboot.

If there are still problems, post a screenshot of the advanced tab if there are any differences now.

You could also look into a firmware update for the router which may help.

I think the next step I'm going to try is to set the Speedstream 6250 as just a modem instead of combo and bring over my extra Wireless G router to test. See if it just doesn't like communicating directly with the 6250. Strange where it was fine with XP though. I suppose it would make sense to try my laptop with the connection just in case something got borked and it was just a coincidence that it happened at the same time as the Windows 7 installation.. you never know.

I don't think upgrading the firmware is an option where his ISP has a proprietary firmware on this thing. I could see if there's a BIOS update for his motherboard too.

Cool. Many times, the ISP will actually assist in upgrading firmware so you could check with them about it.

Still haven't been able to fix this problem. I just brought over my laptop to his house and it runs flawlessly with his Speedstream modem from wireless.

There must still be an issue with Windows 7 or the driver.

Might have to buy a cheap network card to try it...
