Hello Darren! Thank you for your question. I am a licensed network professional with over ten years of experience, and I will be assisting you today.I'm sorry about the issue. What's the model of your windows xp computer? What's the model of your internet/wireless modem/router device?When did it stop working? Is the wireless switch/button/light turned on on the computer?Does another computer or wireless device have the same issue?
If you connect the computer to the modem/router device with an (Ethernet/network) cable, does Internet work via wired/cable connection?Edit: It looks like you are away; please reply back when you are available to continue. Thank you.
