In 386.7 or 386.49447 of AX86U, "160MHz+ch36" will make your router lose 160MHz when an 80MHz device is pluged in.
"20/40/80/160MHz + Enable 160MHz + ch auto + DFS” will make your router boost to 160MHz automatically when a 160MHz device is pluged in. When your last 160MHz device disconnects, your router will drop to 80MHz. And a 160MHz device is pluged in, your router boost to 160MHz automatically again.
Although both versions of the firmware can achieve 160MHz 5G WiFi, the following two things make me irritable:
1. 5G bandwidth of the AiMesh node is always the same as the AiMesh router. This means your AiMesh node is always at 80MHz if your AiMesh router drop to 80MHz.
2. A 160mhz device connects to the AiMesh router when the the AiMesh router is at 80MHz. Then the AiMesh router boost to 160MHz after 1-2 min. But the 5G WiFi disconnects for a split second so that this 160MHz device is connected to the AiMesh node. AiMesh router that lose 160MHz devices drops to 80MHz. Then this 160MHz device connects back to the AiMesh router by AiMesh or 802.11K/V. And the AiMesh router boost to 160MHz after 1-2 min.....................This 160MHz device "jumps" between the AiMesh router and the AiMesh node. Sometimes, it ends up connecting to the AiMesh router with 160MHz. Sometimes, it ends up disconnecting.
I hope ASUS can provide a new Source Code soon to fix this 5G bandwidth issue.
