I use Reliance Netconnect+ in my Toshiba Satellite laptop. My OS is Windows 7 Ultimate. I've seen speeds up to 1500 kbps when travelling and have an average speed of 400 kbps at my room premises.
I'm sorry, I've never felt that much speed while browsing or downloading. Sometimes I think some other programs are also sharing the same network.
It is just showing 200 or 500 kbps but I feel 25 or 50 kbps. Is there any way to prevent them? I use Google Chrome downloaded from Google site. Please suggest me some solutions.
