One Desctop PC,One Notebok, One Smart TV Sony KD-55XE9005,One Smart TV Box Strong Leap S1 and 2 Smart Phones Redmi and Huawei P40 Pro +. Web Page Loading and read News and Info for hardware and softwares of the all world, In smart TV i TB Box Load SmartYoutube Next No Adwares when Watch Video Clips and very rarely do I possibly watch a movie.

I have tried different settings of 2.4GHz and 5GHz with Automatic Channel Selection and channel width disgusting coverage and speed in adjoining rooms and that's why I set myself 2.4 Channel Width: 40MHz on 13 Channel and on 5GHz Channel Width: 160 on Channel: 60 (DFS) Over 60 Channel from 64 to 128 The network becomes Invisible and unusable !!! OFDMA: Enable TWT: Off Smart Connect: Off Mode to AX Mixed Transmit Power: High MU-MIMO: Enable WMM: Enable AP Isolation: Enable Airtime Fairness: Enable I remember that TP-Link AX 20 used a channel width of 80MHz and the speed in each room was the same. It is logical that a 4-core Broadcom processor with 1.5GHz is Better than Garbage Dual-core Qualcom at 1GHz. So I am right to recommend Everyone to Avoid Buying Models 2021 because of the Continuing Engineering Nonsense in the company TP-Link Not knowing Which Processors are the Best. So my Next Router Will Be From Netgear or Asus have Much Better Models More Powerful with Better Range and Speed ​​I've seen Thousands of Tests. The unfortunate thing in this case is how the incompetence in the management and design of your company is at such a low level as your prices. You claim World No. 1 and years of Tradition in Product Design, But Your Allegations Have Nothing to Do with the Reality of the Market in the World of Such Product Types. For so many years of incompetent management, it is normal for things to get worse in TP-Link. Why do you think Apple uses Broadcom processors in its phones? In conclusion, I do not intend to waste any more time and get angry with TP-Link Products! I will give this to a friend and if there is a nice Christmas Bonus I will buy a Real and Perfectly Working Router Although a little More Expensive than your models. Have a nice day everyone and happy holidays. I have no hope of fixing the problems of the AX 72, because I know how bad your engineers are who write software slowly and do not know how to fix it - they deceive customers. This is not a world-class company. mine know how to solve them. Good night!

Used memory 52% permanently when connected 2 Lan and three wireless clients.

Isn't that normal? My AX20 is constantly at 49-50% memory usage, no matter how many clients are connected.
