i was connected to a hotel network which functioned perfectly well until yesterday afternoon. I could only get "local only" access using both the ethernet connection and the wireless connection and the network was unidentified. after much googling, i tried reseting the tcp/ip, flushdns, reset winsock, removed all saved networks and wireless networks. using the ethernet cable, i am unable to connect to the router at all, getting the 169.x.x.x ip. i tested the connection using a live linux cd and the connection was stuck at "obtaining ip address". when i try to ping the router i get the message "ping transmit failed, error code 1231" using wireless lan, i managed to connect to the router but the connection is hgihly unstable, dropping back to "local access only" intermittently. when i ping the router, i get extremely high packet loss of upwards of 74%, with the message "destination host unreachable" most of the time. i'm running windows vista home basic, and the linux system i tested with was backtrack 3. is this a problem with the hotel's router or my computer's connectivity? this problem is only present on my computer, which is a dell inspiron 1420. all other computers and even my cellphone can connect to the hotel's network without any problems.
