Hello, I bought a new Alfa 1000mw adapter for the good range, and I've picked up several new signals...but the problem is the speed of my connection..It can be fine one moment at 4.5mbps and then drop down to .16 mbps in a matter of minutes. Usually once it drops it doesnt go back up until I reinstall the drivers..I have Win7 ultimate 64bit..if anyone can help I'd appreciate it alot! thanks!
