Lost on Ip conflict issue?

[493]

Okay here's the deal. I have a PC and laptop and I recently purchased the PC and a wireless adapter for the PC which works like ass. Gets terrible speeds and goes to limited or no connectivity. I go to try and bridge the laptop with the PC through the laptops wireless and I get smacked with the IP conflict. I tried ipconfig /release and ipconfig /renew to no avail. do i need to set a static IP for each computer or what other things do i need to try? I've also tried enabling internet connection sharing and not fooling with the bridge but then it says cannot enable sharing because the computer already has an IP address used for automatic IP address or something along those lines. I'm stumped.
I'm not exactly sure how to change ip's and stuff like that. I know how to access the router but not how to set static ip's to devices or how to change dynamics to stay in a certain pool
