LAN connection - Unidentified Network - No Internet

[lowsider]

HELP!!!!!

I have installed Win 7 - Build 7100

It worked for 2 hrs and since then all I get is the network icon in the bottom right with the yellow triangle. It states unidentified network - no internet access.

How can I cure this.....

It is a NVIDIA Network controller on a ASUS Striker II Extreme board.

I have the same problem here on a Dell Dimension E520 with an Intel 82562V Gigabit card, but try this: right-click on the network connection icon in the system tray and choose Open Network and Sharing Center. Near the top of the left hand pane, click Change Adapter Settings. Right-click your network adapter and click Disable. After it's finished disabling, right-click it again and click Enable. That seems to clear up the problem here, although I have to go through the same process whenever I reboot.

Nope

No just returns to the same error!!!!

It used to work until I did the latest security update. I may try removing that and seeing...

I had the same problem when I first upgraded to Win 7 build 7100. I found that the network card advanced settings 'WOL & Shutdown Link Speed' had defaulted to 10Mps First. I changed it to 100Mps First and not had a problem since.

 

[The Patient]

Boogieman: is that a Realtek or an Intel card? I just checked my PC with the Realtek, and it has that setting available. It's set to 10Mbs first, though, and everything is working fine.

The PC with the Intel card, on the other hand, doesn't display that option, and that's the one that's having the problem.

May be a silly question how do I check this and change it

My computer has a Realtek card. The change from 10 to 100 got me a network connection that I didn't have. Maybe a driver update for your Intel card or try a Realtek card instead!

Lowsider: Right-click the network icon in the tray. Select Open Network and Sharing Center. In the left hand pane, click Change Adapter Settings. Right-click your adapter and select Properties, then Configure, then the Advanced tab. Scroll down and you'll see the option (probably last in the list).

Boogieman: I've been sniffing around on the Intel site and there are some drivers which appear to be newer, but installation fails -- "not compatible with this operating system".

Hopefully the white coat guys are working on a Windows 7-compatible update.

There is no such option. Mine is a nVidia Network controller on the motherboard... This is really starting to hack me off....

 

[The Patient]

Ah, yes. I should have reiterated that this is just for the Realtek card (thought you had one of those). Sorry.

On the bright side, hopefully the fact that this does not appear to be an isolated annoyance means that it'll be visible on the Microsoft and network vendor radar systems and dealt with before Windows 7 goes gold.

Do an "ipconfig" at a command prompt and look at the "Default Gateway" of your adapter. Is there an entry of "0.0.0.0" first in a list of two gateways?

This is a problem with W7 over any other version of windows because of an extra dhcp feature Microsoft turned on by default. "DHCP broadcast Packet" or something like that. Unfortunately if you are using a Linux based firewall (as I am) or a router with embedded Linux that is a little old (LOTS of home based routers are this way) or possibly some other older OSesthat don't support this feature (or W7 support of it is marginal) Windows, while getting a good DHCP the first time will then NOT get one on second boot and leave the useless temp placeholder of 0.0.0.0 in the table preventing anything from leaving your network from your machine

This is one of a few problems they REALLY need to fix because it is the kind of thing that they can't afford on the back of Vista's "bad image".

I only know of one cheap way to fix it, don't use DHCP. Go to your ipv4 settings for that adapter and turn off DHCP and enter a fixed local net address (you might be able to just use the one listed in ipconfig) and then enter the default gateway also listed by ipconfig. (not the 0.0.0.0 of course)

have you updated your drivers? Nvidia has W7 drivers for 32 and 64 bit systems.

this fixed my problem. good luck

Oh cool, I DL them but the nividia web site driver prober or whatever it was called said I as u to date already, I'll try installing the driver set anyway and see what happens

@lowsider and others,

This looks to be a NIC driver or a motherboard chipset driver issue. Get that sorted out with the vendor. The alternative is to get your hands on build 7127 and upgrade. The new build may fix the driver problem. I hope this helps.

 

[fseal]

Well in my case it's not the driver. Just tried the latest nvidia network drivers and I still get the 0.0.0.0 in the gateway list.

Turns out that the "broadcast flag" setting in the registry is OFF though so back to static IP for now. Hopefully the problem really is fixed in later builds.

I am having a similiar issue, worked for a couple weeks, now i get an "unidentified network" listed and I have to disable and re-enable the adapter to get Internet back. Have to do this on every boot up now. More people are having this issue see this thread:

I too had the same problem in build 7100 but wguimb said It is fixed now in 7127... Im happy beacuse now in 7127 even my HDD Mass storage SATA Driver works and previously it was not so...

guys, this just isnt a realtek problem... i believe if anything it first has to deal with the particular driver for your ethernet chipset... then if not that, then its the nvidia controller. I am in the same boat, only different chipset, not a realtek.

The fix i have found for this has been the following. After you install driver, reboot. In most cases after you then log back in, it will display your ethernet correctly. After another reboot while ethernet still enabled, log back in and you will then see the problem repeat itself. The "trick" for me and this situation was to disable ethernet before reboot, then enable after reboot. This, for me, is the ONLY way to have the controller report accurately. PITA, but the only way for now. Trust me, i've tried every driver on the planet so far relevant to my controller/chipset.

yep, you are correct sir... I had just gotten around to my ethernet, had been fooling with the wireless, and had seen the issue when atleast when wireless drops, and tries to pick it back up i had the asterix/redX. This was a few days ago, with possibly different drivers as i have tried many in the past 3 days, wired and wireless. But i am happy atleast to report that the problem of it not accurately reporting after a reboot has now been fixed. No need for my recently posted "trick fix" for the 7100. This all but flares anger with me as the 27 was compiled TWO DAYS after going public with the RC!!!! You mean they couldnt have tested this RC within the 10+ days between being compiled and the thrown to pub?!?!?!

Is that what we should expect with the supposed "final" release??? have they not learned lessons by now to doublecheck homework?? My 3rd grade teach instilled that in me. Sheeeeesh!:shock::shock:

Not too mention, there was no 2 updates for the IE, or the x86 root security fix. I mean FFS MS!!! then you expect ppl to shell out the bucks for this. And ppl wonder why the piracy goes on? For JUST this reason alone.

:roflmao: MS is like that whether we like it or not!!! :roflmao:
