Please keep in mind that your results may vary due to such factors as:
• Are you using a USB 2.0+ slot?
• Distance from router
• Signal Obstructions (physical or radio)
• Signal Strength
It is worthwhile to note my Cisco wireless adapter was fine in the days of "802.11g", but 802.11n reigns supreme now. Plus, my new wireless USB adapter has more power to it also (e.g. can go through my obstructions of walls to reach the router!!). Both models come with a USB base making positioning the antenna a viable means of signal control.
Since I worked for Comcast, I've been using Speedtest.net to test my connection speeds. It's free and very consistent. You can test your speeds before & after too. Please feel free to share your results!
