I went to Peshawar last week for business purposes. I wanted t connect to the internet so the hotel staff in Peshawar reconfigured my IP so that i can use the broadband.
Now i am back but having problem with my DSL and EVDO connection. I connect to the EVDO device but after 10 mins it disconnects itself and when i try to reconnect it gives error "Port already open. Cannot reconnect." Similarly when I plug in the DSL cable in my LAN card slot it does not connect to the internet but when i change my IP it does. Afterward if i remove the DSL cable from the Laptop and reconnect the same problem occurs and i have to change the IP again.
Please let me know what the main reason of the problem and whether I would have to reinstall the Windows.
