Another unidentified network deboggle

[rock1t]

Ok I know there is three thousand of these posts but Ive tried all the fixes that I could find, or at least i think.


Here is the situation:
I get unidentified network, on any router I plug into.
If I try to enable sharing I get an error.
When I run ipconfig/all:
No connection-specific DNS Suffix
No Default Gateway
Media State : Media disonnected
DHCP Enabled : No
Autoconfiguration Enabled : Yes


Here is some details:
Im trying to use an 8 port switch Dynex dx-esw8
but have also attempted on a Linksys genaric wireless router.
AND on 5 different computers (all windows7)
The Main PC is
Asus G72gx windows7 Premium 64bit (PC registerd on the site)
and the adapter is Realtek PCIe GBE Family Controller

Here is what Ive tried:
Registry editing, that flag something something to 0
Disabling Ipv6 and trying
Disabling Ipv4 and trying
Updating, downgradeing, uninstalling/reinstalling the adapter.
Setting the network adress to random numbers
Setting the WOL & Shutdown Link Speed to 100 mbps first
Turing on/off any shutdown for power saving
Windows firewall is disabled, no other firewall is present
Diagnosing the connection
ipconfig/release
/renew
/dnsflush


Other Info:
When I run ipconfig/release I get An error has occured while reeleasing interface Local Area Connection : An adress has not yet been associated with teh network endpoint.

When I run /renew I get An error occured while renewing interface Local Area Connection : unable to contact your DHCP server. Request has timed out.


Thankyou !

Welcome to Seven Forums!

The big clue is this: Media State : Media disconnected

That right there says you have no physical connection. Most of the time it's a simple thing like a bad ethernet cable. Sometimes is a case of the wrong type of cable like using a cross cable instead of a straight through when connecting to a switch.

Thats interesting because when I do ipconfig it always says Media Disconnected even though my connection is working perfectly. At any rate the Media Disconnected isn't a problem because it always says that on mine.

You may want to enable DHCP on what ever machines you are using and in the router configuration page. That is probably causing your default gateway not to show up which will definately cause problems. After that a router reset will get your DHCP assignments working again.

Hey chev65, where've you been?

Mine doesn't show media disconnected . I checked all four of my systems and none show a media disconnected on the primary ethernet adapters.

The Teredo, tunnel and virtual adapters will show disconnected but the main ethernet adapters shouldn't.

Although I do see that he has DHCP disabled.

Hey Red whats up, my truck broke down a couple weeks ago and I have been busy fixing all the broken stuff on it ever since, new rear brakes, axel seals, alternator,belt, anti lock brake problem, A/C recharge, suspension needed some work also.

Ok back on topic,... My ipconfig always says media disconnected LOL. Some day I'm gunna get to the bottom of this media disconnected thing! I have a feeling it's only referring to a secondary internet connection not being connected, doesn't seem to matter either way because everything works.

Does yours actually say "Media Connected" or does it just say nothing, I still want to see one that actually says Media Connected! :sarc:

At any rate that isn't the one that matters, I concure about the lack of having a default gateway being the real problem here but that's easy to fix.

 

[RedBirdDad]

Glad to see you back. I feel your pain. My daughter's car needs $1,500 worth of work.:sa: Just did the first $500 of it.

There is no "Media Connected" that I've ever seen. Apparently Windows only throws up a "Media Disconnected".

A "Media Disconnected" on a real ethernet port (not a tunnel or virtual) has always meant no physical connection. No cable, bad cable or wrong type (cross vs straight) or a bad port on one side.

 

[chev65]

Yes it's getting expensive for me also, over 2 grand doing all the work myself and not quite done yet, it will be nice to have everything working again though.

I'm pretty sure the media disconnected is refering to an unused internet connection like my secondary network connection being unplugged, I'd be willing to bet that your machine doesn't have a secondary connection like mine does. Remember that guy who was so determined to have his IPv6 say media connected LOL.

Mine says Media State -----Enabled on Windows 7 Ultimate

Actually I do have secondary connections, I just didn't include them in the list. Tunnel adapters and VM connections. the VM shows connected bu the tunnel adapters show media disconnected. Unless you're referring to a second physical ethernet port. That I don't have.

ok I got DHCP to display as enabled and as well as I got the default gateway to come up 192.168.1.1 but Still reads as undentified, I cant go into the 192.168.1.1, no internet and cant see any other computers connected as well.

 

[Bootz]

Make sure IPV4 is enabled and IPV6 is disabled. also is try turning off autoconfig maybe? on mine it just says IPaddress in the ipconfig window.

Well, that's a little progress. You have a physical connection now. What did you do?

Anyway, the reason you still can't see any networks is the PC didn't get DHCP response from your router. If Windows sends out a request for an IP address and doesn't get a response, it assigns itself an address in the 169.154.x.x range.

How you got a 192.168.1.1 gateway is a mystery though. Did you set any addresses manually? When you configure the ethernet adapter in the PC make sure you don't set any manual addresses. The router will hand you an IP address, DNS and gateway addresses in the same range. Take a look at my post earlier. Your addresses will be different but you see what it should look like.

It's possible the registry entries for the adapter have become corrupted. As a last resort you can try uninstalling the adapter then do a reboot which will cause Windows to re-detect it and create fresh registry entries. At that point it's back to the defaults which is normal.

Make sure IPV4 is enabled and IPV6 is disabled. also is try turning off autoconfig maybe? on mine it just says IPaddress in the ipconfig window.

Normally you don't want to do that. The whole idea is to have the router hand you an IP address along with DNS and Gateway info. There are some scenarios where you'd do a static address but under normal conditions DHCP is preferred.

This really isn't an IPV6 issue even though IPV6 has caused problems in some areas. This is a basic connectivity problem so we need to at least get to the point where his ethernet adapter is getting an address. Normally IPV6 is pretty harmless and coexists with IPV4. My own network runs that way. I have both a Homegroup (IPV6) and a Workgroup (IPV4) on the same network with 5 PC's and they all play nice together.

To see more of the details do an "ipconfig /all" at a command prompt which displays a lot more info.

 

[rock1t]

I tryed uninstalling the adapter and restarting and got no effect. To get this far I actually did nothing I went and made sure that DHCP was enabled like you guys had suggested and both the registry and the adapter said it was then I pluged it in and now I have what I have No I have Every possible option on automatic.


I did also try disabling IP6 and that made no difference.

 

[RedBirdDad]

What ISP do you have, DSL or Cable? Also what make amnd model modem/router?

When you uninstalled, did the system give you a "new hardware found" when you booted?

 

[rock1t]

yeah new hardware found and all that good stuff,

The switch Ive been trying is included in original post and the seccond router is the linksys WRT54G

Our provider is Bright House, the 40mb wideband with the phone.

Did this PC *ever* work on your network?

The WRT54G has some unique problems associated with it when it comes to working properly with Windows 7.

I'm not sure what you meant when you said there are two routers but you should only use one router per network or it will cause conflicts with the default IP.

Try using the MAC address clone option which should get that router working for you.

This post by AEM descibes how to do this. He is using the same router and had to use the MAC address clone option to get his WRT54G working with Windows 7.

There are 12 different versions of that same router, some work better than others for Windows 7. A firmware update might also help but you need to get the exact version number for that.

Oh what I ment was I have tryied to connect via eathernet cable to both the dynex switch and that linksys router and I get the same "unidentified network" on both. Sence we have moved all of our computers to windows 7 the only way to connect to the internet is wirelessly.

Did this PC run XP prior to this and connect by ethernet successfully? I'm trying to get a handle on if this ethernet port ever worked correctly.
