I am having this problem too: at home, I can only connect using my anonymous neighbour open connection. When I configure my router with no encryption, I always get a local link. I'm of course 1 foot away from my own router and signal is excellent for every other device. Well. when I assigned the IP, gateway and DNS munually , the connect to my router is ok and I can visit the configure page for the router by 770. But incredible thing happened, I still can not browse the web.....rightly, the router works normally and my other wireless device can get the web smoothly. Drive me crazy.....My neighbor would close his wireless AP every 10pm...
