so this is what happened. i ran the cable out of hte trailor up to the roof an onto a wooden steak where i mounted the antennae. i correctly went through the setup of the AirLive WL-5480USB WLAN USB Adapter and then connected it to my computer as stated. it picked up about 8 or 9 different access points. when i would connect to one the signal would be great and then drop off to nothing and repeated this fluctuation to the point where i have stopped using it. the isp said that it might be because the antennae is so far away from teh wlan usb adapter but why sell the cable then? any help would be great as id love to be able to sit inside the trailer and have internet. like i said when i disconnect the AirLive WL-5480USB WLAN USB Adapter and use just my interal wireless card it works w/o the fluctuation, jsut bad signal. thanks guys!
