Windows 7: Unidentified Network issue in Windows 7 x64 - AGAIN

It was way after the 2nd of March. I've also checked what updates were unstalled on the 2nd of March - nothing hardware-related at all, just Windows Defender stuff.

The first time it lost the network after 2 weeks was on the 7th of March.

Just to get this out of the way - I've just updated the router firmware. It didn't change anything. Every other computer in the office, be it old or new, still works. My laptop shows unidentified network.

Can this be a hardware issue? How does it determine that the cable is plugged and why am I able to manage device settings and reset it then? It's so weird. The power cable socket is right next to the LAN port on the laptop - can this mean anything?

It's so weird. I've had this problem from day one, but I don't understand how the Speed & Duplex setting change could've fixed it once and then couldn't do it for the second time around. It's the same system, the same device, the same driver, the same network. Nothing at all changed, yet everything seems to be different now except for the problem itself.

You should run this tunnel adaptor remover first. Too many of these indicates a driver problem and it will also ruin your connection if there are too many of those tunnel adaptors. This problem happens all the time. Click and save the zip file, then run the zip file and reboot.

Here is what I did:

1. I'm now working on my old laptop. So I took my new one and turned it on. It recognised the network.
2. I'm surprised, of course, so I decide to check for how long it will stay this way. I log in to my second Skype account (I have one just for work) and make a video call to my work account. I go back to my desk and work while checking the small video screen to see when it will be gone. It seems to be stable.
3. I go back to the new laptop and then I have a thought. I pull the power plug out and the connection drops immediately. When I try to diagnose it, it goes back to the unidentified network shit.
4. So now that I'm back to my problem, I run the tunnel adaptor remover. The x64 version doesn't work for me for some reason, saying I have an unsupported system (though I have x64 Win7 Enterprise). i386 works fine though.
5. Nothing happens afterwards.

But here is what I've discovered while I've been doing all this. The following procedure helps to get the connection up and running.

1. Laptop is plugged and is not using bettery.
2. The network drops and goes to unidentified network.
3. I disable the PCIe adaptor.
4. I unplug the power cable.
5. I enable the adaptor and it find the network immediately.

Unfortunately, as soon as I plug the power cable back again, the connection drops again almost immediately and I'm back to unidentified network again. Is this crazy or what?

I'm growing more convinced that this might be a hardware issue. The power socked is right next to the LAN port on the laptop. Can this have some sort of negative influence over the LAN connection?

Please tell me if anyone has any ideas about what might this be. The part that confuses me is that I've had the unidentified network issue from the start and still managed to get it working for 2 weeks with the speed & duplex trick. Maybe that's just a weird coincidence and there was a driver/network problem, but also a hardware problem. Lucky me.

I've done this about a dozen times now and I guess it's official, the problem is - the laptop can't get the network identified when it is plugged. I've done quite a number of scenarios in the last 30 minutes.

1. Laptop working off the battery, power cord plugged in = network lost in 1-2 minutes tops, inidentified network after diagnosing connection.
2. The laptop has no problem finding the network as long as the power cord isn't plugged. If you plug it right after the network is recognised - the network will be gone.

It is possible that the opposite will be true - if the network is dropped while it works off the battery, it will easily recognise the network when plugged in. But so far I didn't have a chance to test this - it didn't drop the network while working off the battery yet.

Battery problems aside, it's not going to work correctly with all those extra tunnel adaptors.
The fact that you have all those tunnel adaptors indicates that you have a driver problem with your network adaptor. Have you tried to update the driver yet?

If you want to get rid of those rogue tunnel adaptor entries then go to device manager, go to view at the top of the page and then select "show hidden devices". Then go to "Network adaptors" and just delete all the extra tunnel adaptors you see there, windows will create a new one automatically. After that check your ipconfig /all to see if they all have been deleted.

If they all don't show up you can change a registry setting to make them all show up "backup the registry first". You should have a nice clean ipconfig after that.

Registry Settings, navigate too the following key.
System Key: [HKEY_LOCAL_MACHINE\SYSTE\CurrentControlSet\Control \Session Manager\Environment]
Value Name: DEVMGR_SHOW_NONPRESENT_DEVICES
Data Type: REG_SZ (String Value)
Value Data: (1 = show all hidden devices)

I just did that, thanks. There was only one tunnel thingy there btw.

The power issue is still here. I wonder what that may be - a BIOS issue, a driver issue or just a plain hardware-related problem.

According to your ipconfig there was way more than one extra tunnel adaptor.

You still aren't picking up the default gateway from your router but unless all those extra adaptors are all gone you won't have much luck with this connection.
