Windows 7: Ethernet Connection Lost (and Found?)

I don't think it's a router or ISP problem. I've connected my router right to the wall and I had the same problem. I'm on a university connection so I doubt it has anything to do with them.

Hi all, I have a ASUS P5Nsli mobo & it's been running with both XP Pro x 32 & x64bit since I bought it 7-8 months ago. I just intalled Win 7 Ultimate x64 & it worked "out of the box" when I put in my ISP details into the onboard Marvell network controller. A few days later I bought a 1tb SATA HD & a 2gb ram stick, taking my system from 3gb to 5gb of ram. Installed both & reinstalled Win 7 on the new 1tb drive exactly as I did before, &, no network access. I went back to the first Win 7 install, as I haddn't removed it at that stage, & it no longer saw the network. I had no problems connecting under XP, so I knew the system worked.
After much checking & rechecking, emails to my ISP ove many days, in desperation, I removed the new 2gb ram stick. Both the Win 7 installs connected the the net with no issues at all. I've since found out, from Marvell, that the issue is that the P5NSLI board was released before Vista, & the nVidia chipset has some "compatabillity issues" with the network controller when there is any more than 3gb of ram. Apparently its unfixable.
Apparently it seems to be a hard wired problem, so no driver or firmware or bios ubdate will work.
Perhaps the P5NSLI is not the only mobo that has this problem since there dems to be a wide range of mobo's with connectivity issues. Just a thought.
Cheers all.

Did you talk to Marvell on the phone or what?

No scottyd, this info came via a reply from Marvell to another persons email on this issue. Here is the full reply from Marvell:-

"We did see this problem with this particular motherboard when using Vista 64-bit. The problem is with the Nvidia based chipset and we are not able to fix this problem. There are a few solutions:
1. Use Vista 32-bit
2. Use Vista 64-bit with 2GB of memory
3. Use Windows XP

Unfortunately this motherboard was released before Vista came out and it has some compatibility issues."

Windows 7 has most likely inherited this issue from Vista as I have no issues under XP 64-bit. The only differance is with solution #2. As I'm currently running 3gb of ram & I have no networking issues with Win 7 x64-bit.

Again, hope this helps.

Hmm, thanks for the info. My motherboard chipset is Intel although I do have a Marvell network adapter.

I don't think that's the problem the rest of us are having, these seem to be windows 7 specific issues. I've just completed 24 hours of testing on a vista x64 install to verify that there are no issues there (i knew this before however after using vista x64 for over a year, i just wanted to make sure)

I've also ruled out Realtek or Intel or whatever network adapter as the cause, and i've ruled out the rest of my hardware with the Vista test - all signs point to this being a Windows 7 software/kernel issue. I will now think about somehow contacting microsoft about it, though i'm almost certain that will amount to nothing

  • Motherboard/NIC: Asus M3N-H HDMI - GeForce 8300 chipset - NVIDIA nForce 10/100/1000mbps Ethernet
  • Wired or Wireless: wired
  • CPU Architecture: x64
  • Upgrade or Clean Install: Clean install
  • Driver details: Latest nVidia for nForce ethernet adapter (73.14), but I tried a bunch of drivers with no luck
  • Problem description: I have a very strange problem. My Internet connection drops randomly, and when I say randomly I mean it can drop 10 times a day or twice a week. The odd thing is if I'm signed in to my Yahoo Messenger when the connection drops, I remain signed in and I can send/receive instant messages with no lag or other problems. Same thing happens with downloads: If I start the download when I have Internet access it continues even if the connection "drops". Meanwhile, if I try to ping my gateway or a random site like google or yahoo, I get "request timed out". I'm unable to browse also. Nothing gets the connection back but waiting. The drop can last for a couple of minutes or several hours. While it's down, I sometime launch my browser and it loads the google homepage, but that's it. I also receive replies from my gateway. Just one or two and then request timed out. Ruled out the ISP problem, because on XP I didn't have this problem and my neighbors aren't experiencing any of my problems. I've tried every possible solution I found on this forum and others, but none worked: disabling rss, disabling IPv6, setting static IPs, disabling all offloads, no sign of the Bonjour service, disabled firewall and antivirus etc.
  • Solutions or Suggestions: none

I've just completed 24 hours of testing on a vista x64 install to verify that there are no issues there (i knew this before however after using vista x64 for over a year, i just wanted to make sure)

I think the network issue I'm having is that, as far as I can tell, only appears on the ASUS P5NSLI mobo under Vista & Windows 7 x64. So my problem may be both a chipset/bios issue, but only shows up under Vista or Win7.
The explanation from Marvell explains the problem I'm having, or rather had now that I've dropped down from 5gb to 3gb ram. (one guy posted somwhere that he had to drop from 8gb to 3gb ram to get his network adaptor working, now that would hurt).
It's entirely possible that a fix could come from M/soft either in a future update, or SP1. Given the age of the P5NSLI, my bios is the latest & it's dated 2007, it's unlikely either nvidia or ASUS will be bothered to release a fix. Regardless of there being one or not.
The only issue I have with the Marvell response is that running a 32 bit OS will only see 3gb of ram regardless of how much ram you have. So you may as well do as I've had to & just have 3gb ram, until she who must be obeyed, allows a new mobo.
BTW, I never bothered with Vista, so I've no idea if my system works with it & over 3gb ram. Although, as an experiment, I might borrow a mates copy & install temporarily to find out. If I do get around to doing that, I'll post my findings.

The only other thing I have to offer up, is a hunch. I don't have experties to test this, so feel free to either investigate it, or tell me it just can't happen.
Could it not be a conflict or an overlap with the way the memory is allocated to the devices on the PC during startup, that only happends in Win 7 x64 when more than 5gb ram is present?
i.e., Say a pci device is loaded & allocated a memory range first, then the on board network adtaptor tries to access the same or some of the same memory range, but can't.
From my limited knowlage of the way PC's & OS's do these things, it sound like there should be some sort of conflict warning. If that is the case, perhaps I've just answered my own question.

Just got my Intel EXPI9301CTBLK 10/ 100/ 1000Mbps PCI-e network card today. Installed it, disabled 2 Marvell NICs in bios, (disabled ipv6 and power saving features for new card as well), started downloading and all was fine for a bit, then it disappeared just like the onboard Marvell adapters. Acted the exact same way. Nothing showing up in network tab of task mananger, system pretty much unresponsive, couldn't open any explorer windows or even click restart, so I had to hit the reset button.

This has to be something with Windows 7 itself and the (Intel) chipset I have. I don't know. Very frustrating
