Running these analyses costs money. Buy through my links to help keep lights on! I may get a small commission.
I’m running BE92u and 2 BT10 as aimesh, not bad though
I also have the BT10x2 system with wired back haul. Rock solid with 50+ devices on my network.
I have two of the BT10 mesh units and it has been rock solid using wired backhaul. Highly recommend. Have about 50 devices on the local network.
Asus zenwifi is a great and user friendly. Get the BT10 or BQ16.
I currently have the Asus BT10's ive not had any issues at all with them. Its been running perfectly for me.
I recently bought the Asus ZenWifi BT 10 two pack and am very happy with it. It is stable, fast, and has great coverage. Plays well with others.
Seconding the BT 10. I also cannot run Cat cable through my home due to having 2 stories and nothing lines up for a drop. I have the base in our loft and the node down in the kitchen. The whole house is covered and speeds are fantastic! I also like Asus for their free software to block malicious attacks that other companies don’t offer.
I just did what you did but in reverse. I replaced an RTAX88u as my master and an RTAX55u as the mesh node. I installed two Zenwifi BT10 and using the rtax88u in the garage where I still have a dead zone. I have never had internet this fast.
I recently bought the Asus ZenWifi BT 10 for a 2 story, 2600 sq ft house. The coverage is perfect and the speed is blazing fast no matter where we are in the house or yard.
My best one so far is this current one... ASUS zenWIFI Bt10 and a mesh node. A third of an acre, and I've got full coverage. At the weakest on wifi, I'm getting 200mb per second. The router is in my computer room. but I the Mesh is in the attic area, and it's using the WIFI 7 backbone, because my wife refused to let me string a cable. :)
