I've set up a wired/wireless network in my apt and after several days of operating without difficulty, the laptop (which is connected wirelessly) now can no longer access webpages. My desktop is wired into the router and has not had any difficulties. I'm using an AirLink 101 802.11g router and a Motorola SB5100 Surfboard modem. The laptop is logged in to the network and I've tried power cycling both the modem and the router and disabled the security on the network. Are there any other basic troubleshooting things I can or should I just get some professional help?
