The main issue in airfiber max is that the ubr device basically the C6 device which is linked up with the A6 APs, they are all WiFi-5 with 8x8 MIMO capabilities. WiFi 5 supports MU-MIMO ONLY in downstream and not in upstream. Also OFDMA isn't there and a lot of other things too. WiFi 6 has it all. So basically, if more than 10-12 connections are connected with one A6 AP and they all use it simultaneously, some of them won't even get their basic plan speed of 30mbps. For upload part, its gonna be worse. Tested this exact theory with my tplink archer C6 (wifi 5) and asus rtax86u (wifi 6). Placed both of them side by side for simulating extreme interference condition. Assigned totally diff channels to both of them (36 for TPLink and 149 for Asus) and even decreased their bandwidth to 40mhz (i know not ideal for 5ghz but took every isolation steps possible). Even then, when i simultaneously used both the connections, both of them slowed down to a crawl even though both isps are diff (Alliance and Jio). Next, i tried the same thing with the jio airfiber router and the asus router. Manually changed the 5ghz channel on the asus router as jio doesnt give any control and in this case, the ping and speed fluctuations were negligible and most of the times, both connections were unaffected. I have noticed this exact issue in my C6 connection too. Near my home, there's at least 6 other airfiber C6 connections (excluding mine) and during peak hours, many times the upload speed gets severely affected. Tested Jio 5G speed from my phone during that time too but it was comfortably giving around 400-500mbps. Hence congestion issue on A6. Wrote an in-depth article about it too. If anyone;s interested, i can send
But since my location already has Jio Fiber (OFC) feasibility, chances are low that I would ever opt for AirFiber Plus.
