wireless

I am using a compaq 8510p with internal wifi. The campground supplies an open wifi hotspot, to which I can connect at close range (30 ft) but not at longer range (300 ft).

Connecting a usb dongle just confuses things. The dongle tries to lock on to all the wifi networks in my vicinity. They are password protected, but my laptop still tries to connect.

I connected a cantenna via usb port and got a signal which said I was connected, but all web pages returned error 'unable to connect to server', despite having three bars showing on the wifi icon.

I believe it because the installed wifi card interacts with the usb dongle. If so what can I do about it? I am using Ubuntu 12.04.
