Hello All,Every time I reboot Windows 7 RC, I lose my internet connection. I'm on a home network plugged into a wired Linksys router bridged to a DSL modem. I can see the other computers on the local network no problem but just no internet connectivity. To fix it, I go into Device Manager, disable my NIC then re-enable it and then I get internet connectivity. I've tried deleting and re-installing the driver, looking for updates etc.The same computer works fine under Windows XP Service Pack 2The computer is - ASUS P4P800SE Motherboard - Onboard NIC, Marvell Yukon 88E8001/8003/8010 PCI Gigabit Ethernet Controller- Intel P4 Prescott 2.4 Ghz, 2 Gigs ramC:\>ipconfig /all Windows IP Configuration Host Name . . . . . . . . . . . . :XXXXXXXX - masked out for safety Primary Dns Suffix . . . . . . . : Node Type . . . . . . . . . . . . : Hybrid IP Routing Enabled. . . . . . . . : No WINS Proxy Enabled. . . . . . . . : No Ethernet adapter Local Area Connection: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Marvell Yukon 88E8001/8003/8010 PCI Gigabit Ethernet Controller Physical Address. . . . . . . . . : 00-11-2F-D5-85-BD DHCP Enabled. . . . . . . . . . . : Yes Autoconfiguration Enabled . . . . : Yes Link-local IPv6 Address . . . . . : fe80::1515:e79b:9b2b:2758%11(Preferred) IPv4 Address. . . . . . . . . . . : 192.168.1.100(Preferred) Subnet Mask . . . . . . . . . . . : 255.255.255.0 Lease Obtained. . . . . . . . . . : Saturday, August 01, 2009 6:29:04 PM Lease Expires . . . . . . . . . . : Monday, August 03, 2009 6:29:08 AM Default Gateway . . . . . . . . . : 192.168.1.1 DHCP Server . . . . . . . . . . . : 192.168.1.1 DHCPv6 IAID . . . . . . . . . . . : 234885423 DHCPv6 Client DUID. . . . . . . . : 00-01-00-01-11-B7-04-49-00-11-2F-D5-85-BD DNS Servers . . . . . . . . . . . : XXXXXXXX - masked out for safety XXXXXXXX - masked out for safety NetBIOS over Tcpip. . . . . . . . : Enabled Tunnel adapter isatap.{B61281F0-94F5-4156-8C8C-4D9C806188F2}: Media State . . . . . . . . . . . : Media disconnected Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Microsoft ISATAP Adapter Physical Address. . . . . . . . . : 00-00-00-00-00-00-00-E0 DHCP Enabled. . . . . . . . . . . : No Autoconfiguration Enabled . . . . : Yes Tunnel adapter Local Area Connection* 9: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Teredo Tunneling Pseudo-Interface Physical Address. . . . . . . . . : 00-00-00-00-00-00-00-E0 DHCP Enabled. . . . . . . . . . . : No Autoconfiguration Enabled . . . . : Yes IPv6 Address. . . . . . . . . . . : 2001:0:4137:9e50:4f7:3794:ba3b:7aa5(Preferred) Link-local IPv6 Address . . . . . : fe80::4f7:3794:ba3b:7aa5%13(Preferred) Default Gateway . . . . . . . . . : :: NetBIOS over Tcpip. . . . . . . . : Disabled C:\>

Hi, Thank you for posting. Based on my experience, I suspect the issue is related to the NIC. At this time, please try the following to check the issue: 1. Assign a static IP Address to the problematic computer: 1) Click "Start", input "NCPA.CPL" (without quotation marks) and press Enter. 2) Right click on the connection that you use for the local connection, and then click "Properties". 3) Click to select "Internet Protocol Version 4 (TCP/IPv4)", and then click "Properties". 4) Please manually assign the IP address, subnet mask, default gateway and the DNS settings referring to the settings of the router or the good computer. 2. Update the routers firmware. 3. Please bypass the router and connect the problematic to the network directly to see how it works. If the issue persists, please also let us know the brand and model of the NIC for our further researches. Thanks.Nicholas Li - MSFT

Same issue here. It works fine with a static IP address but I don't want to leave it that way.I never have this problem on my XP partition.If I disable the network connection and then enable it, it works fine but fails after each reboot.If you search this issue on this site you can see there are a bunch of people with this issue but I'm not finding any resolutions. Search for "windows 7 no internet connection" in these forums.

Hello Davex86,If problem persists, try updating your BIOS.bye

I have this same problem, except I'm not using the RC, i'm using the final RTM version. Win7 Ultimate, 64-bit. Updated with all updates sent over automatic update as of the day of writing this. I see this problem after I reboot or power on the computer. The workaround is simple: after startup, disable, then re-enable the ethernet adapter in the "Network Connections" panel. And no, it's not the NIC because I never had this problem in vista 32 nor vista 64, nor xp 32 nor xp 64 (yes, I've tried all of these os'es on this computer). And I've already installed the latest drivers for the NIC. I'm using an nForce chipset.... the mobo is EVGA 680i SLI. It's a possibility that the problem lies with the drivers. But seeing as how win7 isn't supposed to be a huge deviation from vista, driver-wise, I don't see why the drivers would need to change much. If they don't need to change much, that lessens the chance that the problem is the drivers. I think this is a problem with win7.

This is a recurrent problem with microsoft, that ISATAP thing keep removing networks cards and you can't access to the internet... Why Microsoft support CAN'T find a good solution to their shitty drivers??? OMG we PAIED for WINDOWS, so we are waiting for a decent support! To have your connection back (its not a final solution, but can help), start CMD.EXE as ADMINISTRATOR (in Windows\System32 folder) and type: netsh winsock reset good luck mates.. By the way, the better solution for this problem is to switch on LINUX :) try Ubuntu, its a good one for beginners with linux :)

I hardcoded an IP address for myself and the problem went away. Not a good solution but it was time to move on. It's clear this is a bug.

I performed an in-place update from Vista Home Prem 32bit to Windows 7 Home Prem 32bit.... I also have experienced this same issue, after the upgrade when Windows 7 Boots up I have NO INTERNET CONNECTION. My network in fine, my other 2 PC's on the Network have internet connection. I contacted Microsoft's support unit, they were not able to assist me. My Network card is Built into my Motherboard, Intel(R) 82566DC-2Gigabit Network Connection. I contacted Intel, they directed me to a Newer driver compatible with Windows 7, I installedit but still was not able to get an Internet connection. I was able with the help of Netgear.....to go into my Network's Card Properties and change the setting from AUTOMATICALLY OBTAIN to USE ONLY THE FOLLOWING ADDRESSES....Netgear provided all the addresses and after a re-Boot I have an Internet Connection. I would like to be able to reset the networks' card back to OBTAIN AUTOMATICALLY but cannot until the cause of this issue is identified.Others have experienced this same issue; is there a known cause? Is there a Fix (other thean setting the network Properties to a Static addresses).

Hi Jimerb, same problem here; Dell XPS W 7 x64, have to disable/enable NIC after every reboot. Easy to do but very annoying. Question is: Did you find any cure. I think it's an O/S issue but no W update fixed this. Seems to be thousands of people with this problem. Thanks, mazzono in Sweden

Mazzono, no I never found a solution. I have no idea why this isn't a massive issue for microsoft. I'm using a normal router with nothing special about it. It would be great if anyone is aware of a solution or patch if they post it here.

I want to thank JIBZ31 for the solution above. The command NETSH WINSOCK RESET did work for my computer. I have been dealing with the NO INTERNET ACCESS issue for the past 2 days and finally came upon this solution. After doing the command under the CMD.EXE in Windows\system32 I deselected the IPV6 check mark under the Change Adapter selection within the network connection. THANK YOU, THANK YOU, THANK YOU. I can finally move on to more inportant stuff :-))

Mazzono, no I never found a solution. I have no idea why this isn't a massive issue for microsoft. I'm using a normal router with nothing special about it. It would be great if anyone is aware of a solution or patch if they post it here. I notice I have this same issue with windows 7 64 fully patched. But my VISTA and XP computers on the same network do not suffer this issue, its most assuredly WIN 7 and not some NIC or Router problem like they keep trying to foist off on us here. I ran vista fine on the same network card with never an issue.Other solutions here make me have to restart my computer for them to affect anything, then it rebooted and lost the internet again anyway. A Power cycle (Unplug, wait 20 seconds, replug your router's power) seems to fix the issue though, as windows "refinds" the Internet after that. Pretty obnoxious to have to cycle my router every time I boot up though.
