Thanks. I updated the firmware to the latest => 3.0.0.4.386_41793-gdb31cdc
Now, I can see the enable/disable radio option.
However, I am still bothered by the slow WIFI speed of the MAIN router.
[SETUP]
UNIFI 800Mbps
Main node = 1st floor living area (center)
MESH node = ground floor living area (center)
AP Mode only (Modem -> Mikrotik router -> XT8 Main node -> XT8 MESH node
Whenever, my WIFI6 devices are connected to the MAIN node, it can only get about 300Mbps when I am very near to it (about 1-2m away).
However, if I get further from the MAIN node, I can get about 500Mbps (eg. In one of the bedrooms on the 1st floor).
If I am connected to the MESH node, I can consistently get 500-700Mbps.
I know the 5GHz-1 is maxed out at 1200Mbps (2x2).
The 5GHz-2 (backhaul) is maxed out at 4804Mbps (4x4).
I do not think that's the root cause, but I have exhausted all my knowledge (noob) on how to improve the WIFI speed of the MAIN node.
While the WIFI speed of the main node is disappointing, but the coverage/penetration of the 2 nodes is excellent!
Any help please? Thanks.
[UPDATE]: I just got 760Mbps (webe server) download from the main node just now by literally standing next to it. I also found that different Speedtest.net servers gives different speed result. Now, I am starting to wonder whether the slow WIFI speed is caused by the XT8 or Speedtest.net. I can consistently get 800Mbps through LAN of my Mikrotik router though.
You must update to latest Beta 41994.
That official one might be have problem.
I also have used it and I observed that one of XT8's fronthaul sometimes only will broadcast 20MHz bandwith and not 80MHz and need to be rebooted each time that happen.
Now I'm no longer faced it after upgrade to 41994 latest beta.
Sometimes, the nodes also suddenly disconnect and reconnect back to my main router (AX86U) and now over 100hrs connected, it does not happen anymore.
