We extensively tested the TP-Link Deco M5 in a real environment. Our WiFi-test environment is being redeveloped, because the Hardware.Info test lab moved to Amsterdam earlier this year. Because of this, we were unable to perform tests the same way as you are used to seeing from ust.
The tests have been done in a house from 1994, consisting of a ground - and first floor. It is important to add that this is a house that does not receive full coverage when using a traditional router. In order to measure the installation we used iPerf3. A tool that is also particularly suitable to perform tests yourself. You need two stations, one of them being a server that is running the iperf3-software in server mode (iperf3 –s).
In this case we chose a laptop with a gigabit-connector, that we directly connected to the router of the Deco-system. We also used a tablet (HP Elite X2) with an Intel 8260 802.11ac-adapter with a maximum throughput of 867 Mbit/s. We ran iperf3 on this machine in client-mode iperf3 –c 192.168.1.1 –w 1M –i 1 –P4 –t 60 –R. Based on that we were able to measure the throughput.
Downstairs we measured a throughput of 525 Mbps or 65.63 MB/s on the router. This is pretty good and better than we saw on the Netgear Orbi router. Of course we were very curious about the performance on the top floor of the house. Here, the bandwidth was still 170 Mbps or 21.25 MB/s. Considering you need 25 Mbps for 4K Netflix, this is more than sufficient. The speed of Deco is considerably higher than that of the Velop-system, which only managed to reach 94.8 Mbps under the same circumstances. Despite the less luxurious antenna configuration the Deco performs significantly better.
With these measurements we verified that our client was connected to the satellite. You can do this with the commando [netsh wlan show interface]. By placing the third node you can easily increase the coverage in your house, covering a larger surface area. The speed of the third node was about the same as the second one during our test.
