Here's another thought since am actually in the middle of trying to figure this out. Moving out to 75 feet with a wall in the way, the averages dropped off quite a bit, with TP-Link at 24.4 Mb/s, ZyXEL at 21.6 Mb/s, D-Link at 17.6 Mb/s and Netgear at 10.9 Mb/s.
The quickest average again came from ZyXEL at 67.9 Mb/s, followed by Netgear at 60.2 Mb/s, D-Link at 43.7 Mb/s and TP-Link at 38.1 Mb/s. At the same 25-foot distance, the averages reveal bigger differences. This phenomenon was reproduced by every adapter except Netgear's, and the lesson is that if you're five feet away, plug in via Ethernet rather than use a Wi-Fi adapter.Īt 25 feet from the router, ZyXEL's AC240 registered a maximum of 99.2 Mb/s, followed by D-Link at 96 Mb/s, Netgear at 94 Mb/s and TP-Link at 91 Mb/s. While it is intuitive that performance suffers from greater distances, it's less obvious that being too close to your router can cause issues as well. The transfer rates at 2.4GHz were at their fastest from 25 to 50 feet away from the router, and they dropped off from five feet away (too close) or 75 feet away through an interfering obstacle. In the line chart showing average performance, of the four adapters tested on the 2.4GHz band, ZyXEL delivered the fastest speed across the 25- and 50-foot distances, with Netgear quicker at five feet and TP-Link faster at 75 feet.
In some cases, such as D-Link's adapter at 75 feet, there was a large difference between the minimum and maximum reported throughput. The minimum (red), maximum (black) and average (blue) throughput on the 2.4GHz band is measured by IxChariot at five feet, 25 feet, 50 feet and 75 feet and expressed in Mb/s.
