Wireless Problem: Connected but cannot find internet?!

I ve been having this probem fro about an hour now. I have a pc in the house that is connected wireless its using a linksys pci adapter card, it connects to my router/modem's signal and the signal strength is excellent but it says it cannot find the internet. I figured it was the privacy setting but all the setting are correct there connected to the same SSID. I thought it would be that the cpu was not connected to the default ip but i changed it to match the same ip and the router/modem. Is there any way around this ? can some one help plz ?

 

To connect to a router, your PC must be on the same subnet. Typically this means that the first three parts (octets) of the IP address are different to that of the router, and that last part is different. For example:

router 192.168.0.1
PC 192.168.0.100

At this point you should be able to ping the router's IP address from the PC.

Then the PC needs to have the router set as the default gateway. If the router is connecting to the internet at this point you should be able to ping an internet IP address. For example, 64.233.183.99. Even more useful, is to use tracert which is in effect a glorified ping and shows you the path the pings take. So:

tracert 64.233.183.99

The last stage is to get name resolution working. On most modern SOHO routers, they act as DNS forwarders. So you set DNS (the internet name resolution system) to connect to the router to resolve names. That is enter the router's IP address in the PC's DNS settings. You should then be able to ping an internet resource by name:

ping www.windowsbbs.com

 

Whoops - typing fingers working fast than brain. Thank you for the correction Arie.
