Windows 7 64 bit Unidentified Network - No internet access

[humdinger]

I am tearing my hair out trying to resolve this but to no avail :(

Google shows a lot of results but I have had no joy after trying various ideas.

OK, I have Asus Maximus Formula motherboard (latest bios) router Speedtouch 585 v6 with latest UK firmware. I also tried a Netgear DG834GT which also had similar problem, except that didn't even get an IP (169...)


I tried in no specific order: (Clean install, no upgrade!)

Turning off one of the LAN ports in bios (motherboard comes with two)
"Add default gateway 192.168.1.1 automatic metric"
Disable/Enable Network Card
Uninstall/Rescan Network Card
Microsoft default driver
Newest ASUS network driver
Newest Marvell Yukon Driver
Manually setting TCP details
Disable IPv6
Disable everything except IPv4
The registry edit to change DHCP broadcast flag to 0
The other registry edit to add DHCP broadcast toggle
Reformat and install (with only one LAN port enabled in bios to be sure)

The strange thing is in the Details page there appear to be correct details. Using automatic/dhcp it picks up the gateway correctly as 192.168.1.1 and is assigned an IP from the range specified in the router. Subnet mask is correct to at 255.255.255.0

But always "unidentified network" and no internet connection :cry:

The port is working correctly by the way.

Help please!

Can you ping 127.0.0.1?

If not your NIC is dead.

Try a different network cable, and disconnect / reconnect at both ends just in case its a bad connection.

Also could be a DNS problem.

Hard code primary DNS as: 8.8.8.8 and secondary 8.8.4.4 - Google DNS servers.

Go to RUN prompt and type NSlookup

type in google.com and see if it comes back with a reply...

Two things come to my mind, either a DNS issue or an issue between your router and the internet rather than between your computer and your router.

To see if you are simply missing dns, try browsing to one of these ip's directly: google.com: 66.102.9.106, 66.102.9.99, 66.102.9.105, 66.102.9.147, 66.102.9.103, 66.102.9.104

Do you have other computers connected through the same router that are able to get to the internet? Have you tried using the Win7 Automatic troubleshooter?

Other computers using router: yes, one XP one working perfectly fine (the one I'm using to post this) and also a PDA wireless also working fine. I disabled wireless on the router for testing purposes though.

I have tried a spare router - same make and model. Also a Netgear DG834GT.

Cable should be fine since it's the same one I used before when XP was on that machine.

I could not ping the router 192.168.1.1

I will report back later about the localhost ping.

Tried this and got no reply so I tried the other NIC port and that worked! So that was the issue. Problem solved :bday: Thanks very much :)
