I've been having issues with my LAN since a few days after I installed Windows 7 onto my computer. I have 7 different devices that connect to the internet via the router and my family and I have been having issues connecting to the internet with them at random points. This happens randomly on each computer including the one running windows 7. The router is set to handle up to ten computer at once on the LAN.Anyone else having these issues?

A fewquestions : Are the devices wifi, hardwired or a mix of each ?What are the devices (all PCs, or gaming consoles, or other devices ?) Are they all set up for DHCP, or are the devices set up for static IP ? If DHCP, what is the lease timeout ?When one device experiences a problem, are the other devices on the LAN OK, or is the whole LAN randomly down ?Does it only happen when the Win7 PC is on the network ? (Alternatively, is there 'one' common device which seems to be on at the time of the random drops...)Have you checked the router mfr. website to ensure thatyour routerhas the most current firmware ?A few simple things to try : Power off every device on the LAN, including the router and modem for about 5 minutes. Then power them up one at a time, starting with the modem and router, then the other devices. For hardwired devices, wiggle cords and cables - loose connections or bad wires can certainly wreak random havoc on networks, especially between the router and modem.

I think this is a problem with Windows 7. This started to happen on my network when I added the Windows 7 system. It is locking up my router resulting in the rest of the systems connected loosing connectivity. Always have to power my router on and off. I think there is something about Windows 7 that my and many other routers don't like. I have a NetGear WGR614v6. This use to also be a problem with Vista. Older routers would lock up with it as well. (I have done a lot of Internet research). Its an improvement in the TCP/IP stack from what I understand (There is an article about this on CNet).Good luck. My next step it to find a newer Vista compatible router. Though one would suspect that something in the OS should not effect infrastructure.Regards

I have been having similar issues with my network. I have a Linksys WRT54G version 6 router that messes up wireless when my Windows 7 64bit machine is connected to the network. If I restart the router everything works again until the next morning when I don't get a wireless connection even though the network is visible.I tried resetting my router to all the default settings but still get the issue. I have not tried to hardwire any other computers yet but I would imagine that they will experience the same issues that others are having.The short term fix was to turn off the Windows 7 machine and keep it off the network. I would like to continue to work with Windows 7 but I don't want to have to restart my router every morning.All of my computers use DHCP. The Windows 7 machine is currenlty the only one that is connected via ethernet, the rest of my computers are wireless because they are in a different part of the house. I did change the default lease time and IP Address scheme for the network and neither change helped.

I have IPv6 running on the XP MCE wireless, and both laptops. I haven't seen any connectivity issues. I've had all the devices powered up at the same time, to test the network, and so far (2 weeks) I haven't had one problem. One item that linksys does mention, but doesn't stress it hardly enough, is to print out (or hand-copy) all the various pages of settings, before doing a firmware upgrade. After performing the firmware upgrade, it really does help to do a factory reset on the router (the button on the bottom) and re-enter every single setting, as opposed to carrying the setting over, or saving the settings to a file and reloading the file after the firmware upgrade, and/or reset. After I did a firmware update, I did have some flakey performance, which was resolved by doing a reset, and hand-entering all the setup info again (wireless security, channel changes, MAC filtering, etc...)Hope that helps !

JimVec, thanks for the suggestion. I tried resetting my router and verified that it went back to the factory configuration. Unfortunately the problem still persists. I am writing this from my Windows 7 machine now because the rest of the computers have no network connection. As soon as I turn off this computer and restart the router they will pick up an IP and start working fine. I wouldn't have a problem with it if it only happened once a month or even once a week, but it happens every day no matter what settings I use for my router and only when this Windows 7 machine is on the network.I am checking my network settings on the Windows 7 machine and I don't really see anything out of place. I'm on a "Home" network so access is not restricted much at all.I did just turn off QoS and IPV6 and I guess I will see if that makes a difference, but I think that has been suggested in other posts and probably won't help.

Surprisingly, turning of IPV6 and QoS seems to have fixed this. I would like to wait another day just to be sure and then I'll try to narrow it down to one or the other, but for now I didn't have to restart my router this morning.UPDATE: I know it's probably not important anymore since it doesn't seem to be your issue but I turned QoS back on and everything's running fine so my issue was IPv6. Good luck and I hope this gets resolved for you.

I have turned off IPV6 and QOS as well and it made no difference. My router still locks up randomly if the Windows 7 is connected to my network. My system has gone for as long as 4 hours up time and as short as 20 mins time before I have to power off/power on the router.

Pretty much the same problem here with a Linksys WRT54g version 5 router. My gateway laptop running win7 can see the wireless network but will not connect. Most of the time, a vaio running xp sitting right next to it has no problems. If I turn the router off and back on, both computers will connect to the home network.I just returned from a business trip using various wireless networks in hotels and airports, and never had a problem there.Glenn

For those of you experiencing this problem did the router work with Vista? If it's not compatible with Vista it won't work with Windows 7 either. Here is a test to see if the router is compatible with Vista. http://www.microsoft.com/windows/using/tools/igd/default.mspx Here is a link that describes how to turn off some of the advanced networking features in Vista (and Windows 7) http://silverstr.ufies.org/blog/archives/001035.html You may have to disableTCP chimney offload in the NIC driver. This link is about Server 2008 but it also applies to Vista and Windows 7. http://support.microsoft.com/default.aspx/kb/951037 Kerry Brown MS-MVP - Windows Desktop Experience

I was also having the same problems with my WRT54G router. I even went out and bought a newer router to see if it made a difference - it didn't. But this made me realize that it wasn't the router, and I may have solved my particular problem. I plugged my old router back in.I have an Acer Aspire One netbook. I kept getting disconnected and reconnected every couple of minutes - it was getting really frustrating. Then I installed Network Magic, a program I already owned, thinking if it took over the wireless radio, it might work better than MS7's. It did for a while, then my connection went completely off and wouldn't come back on. I hardwired my netbook to the router and it immediately worked again. There is a radio switch on my net book which I can manually push to the right and release to turn the radio on or off. Originally, there would have been a light to indicate when it was on. I thought that the radio switch no longer worked because there was no light and MS had taken the wireless radio over. (Hope I'm making sense here - I just play around with computers. I never took a course). Aaanywayyy, I right clicked on my router in network adapter settings to bring up the menu, then left clicked Connect while I manually switched the radio back on. It worked! And I haven't had a problem since. I even daringly switched the radio back off - lost connection, then turned it back on again to see if it would work again, and it did! I must have accidently turned it partially off so that I was getting my connection only sporadically. It has a spring action, where you have to push it to the left, then to the right to reconnect.So maybe if you are using a laptop, this could be your problem. I also have W7 installed on my desktop PC which is hardwired to the router and I haven't had any connection problems.

It's Sunday morning and I just turned on my laptop. No problem connecting whatsoever! I put it on standby and when I opened it, I was still connected. So I guess I found my problem. I hope you find yours.

ugh im still having issues ive had to switch back to vista to keep the rest of my household happy

hiI've been having problem with the networking in windows 7. I used to have Windows Vista (32-bit) on my notebook. ( HP Pavillion dv6220la), and everything seemed to work fien. However since i installed the new beta windows, my computer has been having trouble connecting to my router. The lan card seems to be not be identified regularly by windows, because the light on my computer shows it's deactivated even though it is activated.Has anybody having also this problem? Since then i've been having to connect by cable since i can't connect wireless. So I'm thinking to return to Vista, unless anyone knows how to solves this. Does someone how to know fix this problem?Thanks
