From what I have read here about the AX89X I should avoid it at all cost. However, I found your site too late. I just bought a RT-AX89X and Zenwifi CTX8 for my AiMesh setup. Now before everyone tells me about my poor choice; please hear me out. I have everything setup and running for 3 days now with no issues. I have done nothing to push the system only went with default setup. I have Verizon Fios 1G and my test speeds are 780/960. Nodes check out and communicate on AX 5G which leaves 2.4 & 5G AC for clients. There isn't any WiFi 6 if you use the mesh. The fan is running in auto at 1760RPMs with a temp of 80F; cannot seem to adjust the speed. Now let me tell you why I think there has been a reset with the AX89X: Amazon was out and everyone else for a while (thought everyone wanted one) then last week the model was back. All the media praised the unit so I went with it. The S/N I got was xxxxxx-0000008 is this the 8th unit after the reset? The unit came with the latest firmware, H/W ver. A1. Not sure what to do; should I return it or is this a reset worth keeping?
