My windows vista laptop cannot connect to the internet via a wifi router connected to a DSL modem.
I tried using a direct cable connection to the DSL modem, it can connect to the internet.
The problem is with the wifi connection, upon inspection using the ipconfig command I notice a different IP address being leased to my vista laptop by the wifi router for the wireless adapter. It's different from the IP block defined in the wifi router. More like an IPv6 address.
Shall I modify my registry settings? If this is the case, can you help me out on this? This just happened suddenly. Before this the vista laptop works fine with the router. Is there any I can get a windows vista registry file default setting for the network or wireless or IP section?
This is a case of ip address conflict of another network. What you can do, is to release and renew the IP address. Here is the way for that: (1) Open the command prompt (2) type "ipconfig /release" without the quotes and hit the enter key, (3) Type "ipconfig /renew" without the quotes and then hit the enter key. (4) Also flush the DNS as "ipconfig /flushdns" without the quotes and then reboot the computer.
Also make sure that you have the dynamic IP address assigned to your network and computer. You may check here as type ncpa.cpl in the run command and then right click on your 'Wireless network connection' and then click on properties of your IPv4 or V6 you are using and make sure that its the dynamic ip address there.
