I am away from home at the moment and the place that I am staying at has no internet access. Before I left I bought a high gain wireless usb antena and installed it and it works great. I can connect to my uncles house who is a few houses down. Recently I found that my friend who lives next door has a much faster connection so I have started sharing with him, but ever since i've started I have been having these strange problems. When I start my computer I can almost never get internet access through my friend's connection. I keep getting the "dns server is not responding" message. I have tried everything that is mentioned on so many forums to try and fix this and it never works. So after disconnecting, reconnecting, rebooting my network card and a whole bunch of other stuff I give up and connect to my uncles slower connection. This happens almost everyday. Then after getting quite annoyed by the slow connection I try my friends again and it works. Then I try my uncles connection and its unable to connect yet my friends works no problem and once im connected to my friends connection it never disconnects, I have no problems with it once i'm connected. I go through this process almost everyday. At first I thought that it just needed some time so I left it at "no internet access" "dns server not responding message" for a while and that did nothing. Its extremely frustrating because I can never get it to work straight away, but it always ends up working after me tinkering around with it for half an hour and then giving up and I never know what it is that I did to get it to work because it is always something different. If anybody has the slightest clue as to what is going on, could you please help me? Thank you.

Upgrade the firmware of the USB antena.

I'll check the cd that came with it, but I'm pretty sure that there isn't an option to do that.

Hi, You may try to update the driver of the USB wireless adapter to see how it works. You can use Device Manager to install and update the drivers for your wireless adapter. Also, check if the NIC is set to obtain the IP Address and DNS automatically. Meanwhile, please try to boot into Safe Mode with networking to see what the result is.
