I have a Linksys WRT54G wireless router that's worked flawlessly for several years now. But for some reason tonight I've having some wifi issues. I have a mac hardwired from the router as well as a couple other things and they all work fine. But the wifi is not working. Both my iphone and ipad show my network and both show the little wifi symbol in the top of the screen. But it's not actually working. I can't get any web pages to load and none of my apps that require a network are working. I've tried unplugging the power cord for 30 seconds which usually fixes this issue. But not tonight. Any ideas?
