Dreaded "Unidentified Network" after BSOD; No fix seems to work
Hey Guys.
Sorry to just come in here and post a new thread about what I'm sure is a common problem, but I've searched the internet to no avail and am at my wit's end.
Quick info: Windows 7, 64-bit. I forget if I have Pro or Home Premium. I have an Asus Striker Extreme (not Striker Extreme 2. This is an older rig) which has 2 onboard LAN ports (nVidia networking).
I had gotten 2 BSODs recently. I searched what was going on and it looked like it was due to a memory leak in the neworking stack. Unfortunately, before I could do anything about it, I got a third BSOD, and this time when I rebooted I got the dreaded "Unidentified Network". I couldn't get any communication to my router.
I tried everything I could find - route delete 0.0.0.0; netsh int ip reset; netsh wins reset; etc etc. Downloaded updated drivers, nothing. I connected my wife's Macbook to the ethernet cable, and instant connection ... Eventually I just bought a new NIC - a TP-Link TG-3468 PCIE Gigabit Ethernet controller. I plugged that in, installed the drivers ... still no connection.
I tried booting into Ubuntu using a CD, and it didn't have drivers for the new NIC, and I still didn't have connection with the onboard lan. Then I remembered that when I installed Win7 from XP that I had installed to a new HD, so I booted to XP (Win XP 64 Pro) on my secondary drive. I installed the drivers for the new NIC, and BOOM - internet. The onboard LAN ports were still dead. At least I knew the NIC worked.
I disabled the onboard LAN in the BIOS just in case it caused a problem and booted back to Win7. Still no connection to the router. I know the hardware is good - I get internet everytime I boot into WinXP. No internet ever booting into Win7.
My network setup:
Comcast -> Belkin router -> TP-Link TLSG1016D 16port switch -> PC's NIC
All cabling is Cat5e (Full copper, no CCA).
(All other devices on the network work fine, and this machine works fine in XP on this NIC.)
This computer usually gets a static IP of 192.168.2.50. (My DHCP range for this network is 192.168.2.100 - 192.168.2.254.)
If I set the IP address to DHCP, I get the 169.x.x.x "GFY" address. If I set the address to a static address (.2.50, gateway .2.1), I get "communication" in that I see incoming packets, but not many of them and they come in slowly. "ping 192.168.2.1" sometimes reports "no response" and sometimes reports "no route to host found".
Firewall is disabled. Antivirus is AVG; all internet/network "protection" is disabled. I have no Bonjour anywhere on my machine that I can see (checked services, etc).
Things I've tried (multiple times and in combinations):
- "Diagnose problems with this connection" (LOL)
- Buy a new NIC (see above)
- Router reboot (Multiple times)
- Different ports on the switch.
- Direct connection to the router.
- Direct connection to the cable modem.
- netsh int ip reset
- netsh wins ip reset
- ipconfig /flushdns
- disabling IPv6
- disabling "network sharing discovery"
- all permissions on public networks
- set this network to my "home network"
- force set Speed/Duplex (tried 10/full, 100/full, 100/half, and 1Gb/full)
- tried multiple static IPs (.2.53, .2.80)
- deleted all networks from registry
- add reg key *NVis... something - kept it from showing in Network Center, but didn't help
- clean boot (msconfig - disable all non-MS services)
The last two items on my list:
1. Uninstall AVG (required for my work ... if this works I'll need to deep dive it )
2. Clean Windows install (/sadpanda)
Before I do that, I was wondering if anyone else had any suggestions. It really looks to me like my onboard LAN died so hard it took Windows networking with it ...
Thanks in advance.

Used to have network; now I don't. Network works fine in XP. No fix seems to work. WHAT DO?
note: I'm at work now, but will update this once I get home with more information.
Also, I don't know what the forum's policy on images is, but I uploaded a picture to imagur at bzneLdw, which shows the status with a static IP and no commuincation, despite packets going out and coming in.
Thanks!
