Mac Forums

so i set up a home wifi network on my mac using a Apple Airport extreme and am having issues trying to get a PC to get anything from the network. The network is working properly as i am on it right now on my mac and i have used it on my iphone PS3 and Xbox. On my PC it recognizes the network and after when i enter the password for the network the PC is saying that it is connected to the network but when i go to the browser and try going to any site i get a page that says "internet explorer cannot display the webpage" it then has a "diagnose Connection Problems" and when i do this it says "your modem or router is not available" and tells me to rest my my modem or router and then it also gives me the option to "Automatically get new IP settings for the network adapter 'Local Area Connection'" and when i did this option it says asks me to either look for another WIFI network or plug in to the network with a ethernet which i did the ethernet. it then says "windows tried to repair but a problem still exists. There might be a problem with one or more network adapters on this computer." im not super computer savy and i hate PC but i need to get this one on my network. I do know that i have had the PC working on a different wifi netork through an Apple airport and it did work and i do know the PC is running vista. if somebody could help me trouble shoot this and possibly give me a step by step since i have no clue what im doing i would greatly appreciate it.
