Windows 7: Unidentified Network - No Network Access, since downloading Windows 7

Unidentified Network - No Network Access, since downloading Windows 7

I had Windows Vista and everything was fine, today I decided to use my free Windows 7 upgrade and I can't connect through my router. It started when I downloaded Windows 7 and I went to connect and it showed my network it said "Unable to connect to "network"". Then after a little why, it didn't even show my network their at all. It just said "Unidentified Network, No network access". I've tried nearly everything, I'm connected now through the modem, but obviously I want to fix this situation with my router so I can connect through my router.

Also, every since I got Windows 7, I can't go to my routers IP address at http://192.168.1.1 - it just won't open the page. I was going to reset all router settings to default but it wouldn't let me access it.

I did read a lot of the other threads on this subject, I've tried Disabling then Enabling Local Network Connection, didn't work. Please help me guys.

This problem usually has to do with a secondary default gateway in the Windows 7 network adaptors Ipv4 settings. The link below shows you how to fix that problem.

Windows 7 Unidentified Network, Limited Access, No Internet Connection Problem Resolved
Sorry that didn't work. I put in 192.168.1.1 as the default gateway and to no avail. One thing I'd like to note, when I put IPconfig into command prompt, the autoconfiguration IPv4 Address was 169.254.XX.XXX ill leave last 5 numbers blank. Was I supposed to put that as the default gateway? or the 192.168.1.1 (which I did put as the default gateway).

Usually the IPv4 address will use the first part of the default gateway so the IPv4 address should be 191.168.1.XXX, the XXX being assigned by your router. You can also enter this info manually in your IPv4 network connection properties window. The correct default gateway also depends on which brand of router you are using.

I believe the ipconfig showed you the address assigned by your modem.

In most cases simply resetting the router by using the routers reset button will fix this type of problem. Although certain routers require that you update the firmware in order to work properly with Windows 7. Just set the IPv4 properties to use DHCP first then reset the router using the hidden little reset button and reboot your machine.

By resetting my router, at least my network was shown on the list now, yet when I try to connect is says "Windows can't connect to linksys".

I see my connection on the list now, it just won't connect. And the most frustrating part, I can't go to my linksys routers setup page because it won't show up, prior to downloading Windows 7 it asked me username and pass and then it let me configure, now it just doesn't do anything.

Let me explain the IP addresses between modem and router (I can connect to modem, but can't to router).

Router (can't connect)
Auto-Configuration IPv4 Address: 169.254.XX.XXX (I'm putting X's in the last spot on purpose just because I don't want to give full address)
Subnet Mask: 255.255.0.0
Default Gateway: Blank (nothing shown here)

Modem (this works fine I can connect and it has totally different IP addresses)
IPv4 Address (note it doesn't say Auto-Configuration like the Router does): 98.220.92.XXX (again I purposely put X's at the end because I don't want information given out)
Subnet Mask: 255.255.248.0
Default Gateway (this has one, unlike the router): 98.220.XX.X (I put X's to avoid giving away the whole thing)

So there's a lot of information for you guys, please help thank you.

My router is a Linksys WRT150N Wireless-N Home Router. It's not very old and worked perfectly with Windows Vista. Also I checked to see if there was any firmware updates, but no there isn't any new ones.

Also, if you need any information to help me please let me know what info you need.

That router should be working for you without any problems. I'm not so sure this is a router problem as you described earlier.

Are you sure you have the chipset drivers installed properly? You might want to look in Device Manager to find that out.

It might also help to uninstall your wireless network driver and let Windows install the default one for you.

It should be able to access your routers set up page by typing in 191.168.1.1 in the URL of your browser. Set it to use DHCP if you want the IP's assigned automatically.

Maybe the Linksys support page will help, with wireless routers you need to start the set up from inside Windows 7. It's a farily simple process. http://homesupport.cisco.com/en-us/w...sysbycisco.com

Upgrades can also be problematic so if you are still having problems setting up your router it might work best to perform a clean install of Windows 7.

Another problem I've seen with Vista to Windows 7 upgrades is that winsock gets messed up and needs to be reset in order for your browser to work properly.

1. Click start, type cmd in the Start Search box, right-click cmd.exe, click Run as administrator, and then press Continue.


2. Type netsh winsock reset at the command prompt, and then press ENTER.

Note If the command is typed incorrectly, you will receive an error message. Type the command again. When the command is completed successfully, a confirmation appears, followed by a new command prompt. Then, go to step 3.


3. Type exit, and then press ENTER. You should be prompted to reboot, if not you should reboot and test.

your modem IP address is a WAN address not an internal one, the default gateway there is actually your ISP's gateway (which is hidden from you when you use a router as the router just broadcasts itself as the gateway) and so the IP address being different on the router is not the issue as far as that is concerned

I dont suppose its possible the router has failed? that seriously sounds like a DCHP issue to me.

The router hasn't failed. The lights on it are perfect and my connection shows up on the list, it just won't connect to it. Let me show u a pic (check it in the attachment). My connection is the one that says "Linksys" it won't let me connect to it. Even stranger, when I enter the linksys IP in my browser, I can't access the setup page, it doesn't even ask for a username and password like it used to.
