Windows 7 and Wi-Fi router report different speeds: whom to believe?

With older wi-fi driver

Win7 reports 90 Mbps

Router reports 72.2 Mbps

With newer driver

Win7 reports 72.2 Mbps

Router reports 150 Mbps

Whom to believe?

It is about the speed between the computer and router.

How this test can show the speed between ROUTER and the COMPUTER?

Open Network & Sharing click on the WiFi connection

And this sheet shows speed different from what router shows. About which fact I started this topic.

Simple. Download some file from the net, note what size the files has and time how long it takes.
1 Mbps = 125 Kilobytes per second.
Should be easy enough to calculate.

Some browsers/download managers do that automatically for you. For example the old Opera (presto) indicates the rate after a file stopped downloading. But the modern, dumbed down browsers might not do that, so lauch windows calculator and do it yourself if you have to :P

But I would trust Windows more than the router.

And this Data Rate WILL be the speed between router/wifi adapter. Your global speed is limited by the slowest, which I'm pretty sure is the wifi connection.

I am not so sure. My internet connection speed is just 15 Mbps. How can I measure difference between 72 Mbps, 90 Mbps and 150 Mbps?
