This is the connection handshake synch'ed with your wireless router that your looking at I believe. If you run
www.speedtest.net from each one you will get better results to know what the actual bandwidth is, which if you only have 1 laptop going on wifi should be close to the maximum bandwidth your ISP gives you with your plan. If any other devices are using bandwidth your results on the computer testing bandwidth will be affected as for any devices on wifi that are going outbound or downloading at the same time of this test will all be competing for bandwidth and will report a slower connection. So this test should be done when either the other computers are off or idle and not running out to the web.
My connection is like 20mbps download and 12mbps upload with comcast cable.
My wireless on my laptop states 54mbps connection, and this is the rate at which it is synch'ed with my G - Router at 54mbps and my ISP connection at 20 down/12 up mbps is the bottleneck. Running this speedtest during a low internet traffic portion of the day, when most are offline late night etc will give the best results to show maximum values. If you run this at a busy part of the day when the ISP is busy with everyones traffic and many people streaming netflix etc your bandwidth with your ISP will show lower results due to congestion.
