I bought windows 7 Ultimate, and installed it onto my windows Vista laptop, and everything is running smoothly. Until I tried to connect to my wireless router, but it keeps saying that I connect with limited connectivity, and troubleshoot says that it " does not have a valid IP configuration".

here is my ipconfig/all stuff...

can anyone help?
 
Solution
The 169.xxx.xxx.xxx usually means Windows is not able to connect to the router or your next device.

If you are showing a strong signal and have any wireless security set in the adapter, I would try to set in a good address to get you started. Sometimes this will reset the system and you can change it later. There may be other things to try like resetting the TCPIP using the netsh commands.

But for now, just try inputting a reasonable address for your system (maybe 192.168.1.5 depending on your setup), with a 255.255.255.0 mask, which should fill in, and the router address as the Default Gateway. If you don't know, you can do this in the adapter properties, IPv4 properties. Type ncpa.cpl in the Start menu search box.

169.254.x.x is automaticly assigned when the computer cannot communicate with the DHCP. I say to telnet your router and check the DHCP settings.

You have tried the Diagnostic on the Network and Sharing Center? Maybe click on the red X.

You are using the correct SSID?

Are you using encryption or any type of MAC filtering?

I will give you this link, it is for XP but seems fairly comprehensive. You may be able to find others.

The command netsh int ip reset resetlog.txt from the link has been reported to have helped at least one poster.

Let us know. If you have a good signal and encryption in not involved, you should be able to use the manual IP addresses, even if DHCP is not working.

Which Cisco Router? model name, model number, revision number..... link to specs? Firmware version you have installed currently?
Dri ver date and version number for Realtek RTL8187SE Wireless LAN? Realtek
