when you renewed the ip address, windows assigns an ip address of 169.xxx.x.x, this your router will not be able to see.
if you have enabled dhcp in the router, check that the wireless card is set to obtain an ip address automatically.
If you have no luck that way, go to another pc and in the network card properties, look at the assigned ip address number that the router has given the pc, eg 192.168.2.2, if you have more than two pc you can bet that the other number assign wil be 192.168.2.3, so go to the problem pc's network card problem and and set the ip address manually to eg 192.168.2.4 and set the dns address to 255.255.255.0, save settings and try connecting again.
the only other thing stopping a conection would be if the security, eg wep or wpa is enabled and the number has not been entered correctly into the network card properties.

- try using the wireless without the wep enabled, but what lazyboy means is, when you right click on the network icon in the taskbar you can select the option to view all connections and in the next window there should be a list of all the available connections in your immediate area, see if yours is there if so click on it then then choose connect automatically, but automatic or manual your router should still allocate the address, you should see a list of all the address allocated in the routers settings under 'DHCP clients' or a similair wording
