Hi all, first time poster. This has been driving me crazy over last 2 hours. We had 1 laptop and 1 desktop. We used to have router hooked up to the desktop. However, due to personal reasons, I'm having router connected directly to my laptop and have desktop use wireless using wireless adaptor. My laptop will be used as desktop for now till I get a new desktop. Internet works fine when laptop is connected directly from Cable modem. However, when I connect router (using EasyLink Connect), network would look for network address, properly find IP address, then go to "Invalid IP address, limited or no connectivity" stage 5 seconds after. I've tried resetting winsock settings, manually setting IP address (and gateway etc), and using different type of cables, including CAT5 cables. I've also downloded SP2 link (hotfix) that was found by searching this forum. What can I do? Router shows red light on "Diag" section, but I don't know what it means. Router is BEFW11S4 v.3. Please help!
