Hi i have a problem with my router. The router is wired to my desktop computer and I have a laptop that uses the wireless signal. The problem is, when I turn off the wireless signal from my laptop my router seems to be working fine on my desktop and I can go online and stuff. But the moment I turn the wireless signal back on, my router just disconnects and I can't access to any website. I'm running on windows XP Thank you very much!
