ok so here goes. all was working perfectly fine yesterday. i brought my netbook to work as usual to connect to our unsecured wifi network....never an issue. i started getting "limited access" and "unidentified network" messages. apparently, after a brief search of the internet, its a common and troublesome thing. i tried EVERYTHING i could find on google and other forums about it. Hardware: Acer Aspire One D260 netbook, Atheros WLAN with up-to-date driver. What i have tried with NO success: 1.) disable / re-enable the wireless card 2.) update, rollback the driver for it 3.) confirm the properties for the IPv4 and IPv6 were set to auto detect 4.) ran winipconfig, reset winsock, release and renew IP.....etc. all of the command line functions i could find 5.) system restore to 5 days ago when i get all of my ip info for the computer, it is showing the ip for the wireless adapter is 169.254.xx.xx which from my reading is an erroneous address. when connected to the same network via iphone, it shows a proper 192.169.2xx.xx ip address. ive tried everything and cant get it to work. i CANT reset the router since i dont have access to it. but then again, since my iphone connects to it properly, so should the computer. i will try to connect to my home network shortly when i get home. any other ideas short of reinstalling windows and WHY does this happen???
