WiFi roaming experience

WiFi roaming experience


The two WiFi Mesh systems make use of the 802.11k / v standards for WiFi roaming, in addition, the TP-Link has Fast Roaming with the 802.11r standard. The tests we have carried out is to make a video call via WhatsApp, which goes through the Internet, and later we have also carried out tests with a laptop and the Intel AX200 WiFi card.

With the ASUS ZenWiFi AC Mini CD6, the WiFi Mesh performance has been perfect, as we explained in our complete review. We have started the video call in the attic, and later we have gone to the main room and the ground floor, at all times we have verified that the video call has not been cut, and in fact, we did not notice any cut in the wireless connection, the operation is really excellent, roaming without WiFi cut-off. Once we are in the living room, we have gone to the attic again and the operation has been the same, without interruptions in the video call. Something that has impressed us about this WiFi Mesh, is that when we did this same test with the laptop and the Intel AX200, it did not even lose a package when making the transition,

With the TP-Link Deco M4, the WiFi Mesh performance has been really bad. We have started the video call in the attic, and later we have gone to the main room and the ground floor, in each access point jump we have a very important communication cut-off, in fact, WhatsApp tells us that it has lost the connection and that the video will be paused. Another important detail that we have realized is that if you place yourself in the middle between two nodes, we will have continuous network changes and continuous communication cuts, we will have about 3 seconds communication and another 2 seconds without communication, making the video call is impossible. This in the ASUS CD6 does not happen, in addition, if we have a PC or console via WiFi in a "fixed" way at home, and roaming occurs between two nodes,

We have tried to perform a total of 9 roamings, and at all times the behavior is exactly the same, the connection is cut with each AP change.

In the case of using the Lenovo X1 Carbon laptop with the Intel AX200 card, the behavior is clearly worse than the ASUS, we have loss of a packet or a latency of up to 700ms, in the following captures you can perfectly see when it is doing the WiFI roaming, you can see that latency increases and you even lose a packet.

In summary, the experience with the ASUS ZenWiFi AC Mini CD6 has been excellent, however, the TP-Link Deco M4 has been clearly disastrous, both with the Huawei P30 smartphone and with the Lenovo X1 Carbon laptop and with the Intel WiFi 6 card. AX200.
