Disconnecting

I have a UM175 and a Netgear MBR624GU, all of which are brand new. I used to have a Broadcomm MBR1000. When I first got my card I had no problems with connection and I was even able to play on xbox live without much effort. I have only had my aircard for about six months and now everytime I try to connect to a game or put any kind of strain on my connection like downloading or streaming or connecting to something that takes more bandwidth it disconnects and shuts me out. Just surfing the internet doesnt make it do that at all. What am I doing wrong? I have switched out aircards and routers multiple times and even switched to a different router as stated above. Does anyone have any idea.
I have a custom built pc with dual core 2.4 4gb ram and running vista ultimate 32-bit and i have four bars of signal all the time.
