I recently used the windows 7 upgrade program to update my laptop from Vista Home Premium to Windows 7 home premium (64 bit). I am a college student and have not experienced any difficulties with networking in my dorm, but returning home on thanksgiving and winter breaks I have found that my computer, upon attempting to connect to my home network, is causing problems for our router. I first installed windows 7 at home and, while I was having no difficulty connecting to the internet for the few days I was still using Vista, after first booting up my computer with Windows 7 installed, I found that I could not connect to the internet. Additionally, members of my family told me that their computers could not connect to the internet either, and after some experimentation we discovered that they could connect only after resetting our router after my computer had been turned off or its network cable unplugged and wireless radio disabled. When I run the network troubleshooting application, it identifies the problem as saying I need to check my network router, suggesting I reset it. At my home network we have a netgear router and outside of the one problematic machine I am running Windows 7 on, the other computers all run windows XP. Attempting numerous times to reset my router with all other machines on the network turned off I found that I would have internet access for anywhere from one minute to two or three minutes before the connection failed again. Turning off my Windows 7 machine and then resetting the router caused all the XP machines to have internet functioning normally. As soon as I would boot up my windows 7 machine and attempt to make an internet connection, the connection would fail for all other machines on the network. I am not certain how to go about fixing this, is this problem normal?

Seems several people with Netgear router/switches are experiencing problems because some models are not compatible with Windows 7. You may have to install the latest firmware on your router. You could also try (to see if it makes a difference) to disable the IPv6 in your wireless and wired NIC properties. While you're in those properties. also disable any power saving features of the nics. MCSE, MCSA, MCDST

No, that problem is most definitely not "normal."First thing I'd suggest (as this will (dis)prove the Win7 box's network settings as being the cause of the issue):On one of the other PCs, open a command prompt, and run the following command: ipconfig /allBoot the Win7 machine (or, connect it to the network), and wait for the connection to fail. Run the same command again, in an new command prompt on the same machine that you did it on originally.Paste both into this thread. To copy/paste a command prompt: right-click anywhere in the command window > select all > <enter>. Full contents of the window are now copied to the Clipboard; simply Paste into your reply. Repeat for second command prompt.I'd also recommend checking Netgear's site for a possible firmware update for your router.-Chris[If this post helps to resolve your issue, please click the "Mark as Answer" or "Helpful" button at the top of this message.

Installing the firmware update from the netgear website solved my issue. Thank you!

I'm having a similar issue with a new gaming laptop I purchased myself for Christmas that has Windows 7 Home Premium 64-bit on it. Apparently, the new machine is also on the same network with a high end gaming rig desktop (with Windows Vista Ultimate 64-bit) and an old Dell Dimension E510 desktop with Windows XP Pro SP2. Now when this new laptop (an ASUS Republic of Gamers G60 series laptop) is on the network it and the Vista machine get Internet together no trouble. Here's where it gets interesting. As soon as the XP machine uses the Internet the connection dies for everyone on the network! Once the router is reset everything is back to normal...until the XP machine goes net surfing again. The router involved was an old Linksys Wireless B router (model BEFW11S4 rev. 4.0 with latest firmware). New router involved now is Linksys Wireless G router (model WRT54G2). Now the OS on the old Dell is SP2. If I upgrade to SP3 will that fix anything? Are there any other ideas aside from upgrading firmware and upgrading OS SP on questionable desktop? Write back with your thoughts y'all. Out!

We just purchased the Netgear router, model number WNDR3400. When trying to install it on our windows-based network, it will not work at the Netgear router requires non-static IP address for each computer whereas our Windows XP network requires statis IP addresses. With static IP addresses on our computers, we get access to the network and internet for only a few moments at a time. This simply will not work for our network. I am bummed as we use this router at home and it works great.

Hi missoulalawfirm The "default" for routers is to manage the issue of IP addresses, which is why the Netgear works well at your home location. However whilst such a scenario works well in home environments, in the workplace different constraints may well be needed. To identify the precise settings instructions that you need to follow please see the Online User Manual on the Resource CD supplied with the Router. If you have misplaced this then download a copy from Netgear's web site. It is possible that part of your problem might well revolve around wireless security. Because on page 30 of the manual there is a reference to "While the router is in WPS enable mode (a maximum of 2 minutes), wireless security is not enabled Follow this link to Netgear’s manual, which you download in standard acrobat format – a PDF file.
