Have upgraded to Win 7 Home Premium, and our network connection keeps dropping randomly. When it does, I can reconnect promptly without any problem. I've told Win 7 not to turn off the network adapter's power. Internet Options has been told not to shut off connections. Any idea what I should look at or check next? It's an HP Pavillion a1730 with an onboard (Marvell) NIC, a Dlink Router, and an ADSL connection. It worked fine under Vista Home Premium before the upgrade.

Hi Denise, After researching from the HP website, I cannot find the HP Pavillion a1730 network card driver update for Windows 7. I would like to suggest you try the following steps to update the network card driver. 1. Click Start, type Devmgmt.msc into Search bar and press Enter. 2. Expend and right click your network adapter, click Update Driver Software. 3. Click Search automatically for updated driver software. You may also perform the following steps to check the issue. 1. Click Start, type Devmgmt.msc into Search bar and press Enter. 2. Expend and right click your network adapter, click Properties. 3. Switch to Power Management tab, uncheck Allow the computer to turn off this device to save power box and click OK. If the issue persists, I also would like to suggest you test the issue in Clean Boot. Good luck!Arthur Li - MSFT

Hi Indeed it sounds as like Drivers problem. If none is available in the HP Support site, you can try the Support site of the Motherboard chipset manufactuerer, or Marvel Support. I think I saw new Marvel Win 7 OEM drivers. Jack (MS, MVP-Networking).JackMDS

I'll look into the drivers. I remember under Vista any time the computer was rebooted we had to put the computer into sleep mode once before the onboard nic would work correctly. That was only solved by going back to an OLDER Nvidia networking driver. It is a Marvell chip but not one listed anywhere on the Marvell website, and it seems to use an Nvidia networking driver, presumably because it is an Nvidia chipset. But I'll check out Nvidia's website too. Thanks again.

Hi Denise, Whats the current situation? Have you contacted HP Support and Marvell Support for when they will release a network card driver for Windows 7? Note: Microsoft provides third-party contact information to help you find technical support. This contact information may change without notice. Microsoft does not guarantee the accuracy of this third-party contact information. If they dont plan to support Windows 7, you may need to purchase a Windows 7 compatible network card.

Thanks. I've always liked HP products, but unfortunately even on popular products they don't seem to upgrade drivers etc. There's nothing for the a1730n. I had to replace our scanner and, not surprisingly, I decided not to buy an HP one. Our new one is from Cannon. Nvidia seems to be concentrating on their video cars, not their chipsets. I did find a generic Mavell driver, for Win 7, but it hasn't helped at all. Last I checked, ASUS didn't admit this popular motherboard even existed because its supposed to be a custom one for HP. But it cant hurt to check their site again. So, still working on it. Denise

No luck from asking Windows 7 to update the driver. What makes it all the more frustrating is that I had found a driver that worked for Vista. HP has nothing updated for the a1730n for Windows 7. The computers are only two years old and a lot of the parts were used in other HP computers too. But they're no longer on support. And I've found nothing on the Nvidia or Marvell websites --- their websites don't even admit to the existence of these OEM parts.-+ So, I decided to try a D-LINK DGE-530T. Tried it both with the driver that came with it, and with the one Windows 7 found. IT STILL DROPS THE CONNECTION! OCCASIONALLY. :( So maybe not a driver problem after all, but something in Win 7? .... Any ideas? Denise

Hi Denise, If this is a Windows 7 system issue, you may perform an In-Place upgrade to repair the system. In-place Upgrade ============ 1. Start the computer. 2. Insert the Windows 7 DVD in the computer's DVD drive. 3. Use one of the following procedures, as appropriate: a. If Windows automatically detects the DVD, the Install now screen appears. Click Install now. b. If Windows does not automatically detect the DVD, follow these steps: b1. Click Start, click Run, type Drive:\setup.exe, and then click OK. Note Drive is the drive letter of the computer's DVD drive. b2. Click Install now. 4. When you reach the Which type of installation to you want? screen, click Upgrade to upgrade the current operating system to Windows 7. Good luck!Arthur Li - MSFT

Arthur, I already did the In-Place Upgrade to Windows 7. Under Vista we had a rather strange problem that the on-board NIC had to go to sleep ONCE before it would work correctly. I did find a driver from Nvidia that fixed that. So I expected everything to work well with Win 7. But since the upgrade to Win 7, the network connections keep dropping every now and then. This happened with the built-in Marvell chip and the Nvidia driver. It is happening now with the add-on D-Link DGE-530T network card and its driver. And I used the update feature to get the latest drivers from Windows Update. The connection drops LESS with the D-Link. But it still drops occasionally. So there's still something wrong. Thanks in advance if you have any ideas.

Hi Denise, In fact, In-Place upgrade is a repairing installation. After that, the operating system should be good. If In-Place upgrade cannot fix the issue, it should not be a operating system issue. According to your feedback, it seems that the NVIDIA nForce network controller is in use. If so, you may try the following steps to check the issue. Disable Receive-side scaling for NVIDIA nForce network controller ======================================== 1. Click Start, type Devmgmt.msc into Search bar and press Enter. 2. Expend Network adapters, right click on the NVIDIA nForce network controller and click Properties. 3. Switch to Advanced tab, highlight Receive side scaling under Property list and select Disable under Value list. 4. Click OK. Recently, we receive some reports about the same issue with NVIDIA nForce network controller. The current NVIDIA nForce network controller driver cannot support receive-side scaling feature normally in Windows 7.

Well, I'm now using the D-Link DGE-530T because it is dropping less. But it is still a problem. I did notice that Microsoft had Marvell write the latest driver for that. So I am rather suspicious that Marvell might be partly to blame even though I'm now using D-Link. The DGE-530T has no 'receive side scaling' listed among its properties. Only receive buffers which is set to 50. I'm tempted to switch one of the computers back to the onboard NIC to try your suggested solution ....
