@BanglaShoppers  use 160mhz channel 

  @Joseph-TP 

Thank you my friend for the reply, this solution didn't help for me. So still need investigation from the support engineers.

Hello @Pankajuuuuu 

If you use 160MHz channel width, will throughput be improved? Or will wireless speed and coverage be improved?

May I know your complete topology?  For example, ISP modem—AX53—AX12(AP mode) — client devices

(Note: — stands for wired connection,)))((( stands for wireless connection )

The tech team has been made aware of your case; they will likely reach out to you via email to continue troubleshooting. Please check your email inbox and confirm.

The overall throughput capability hasn’t changed, but the effective range has decreased across all channel widths.

For example, on 160 MHz, I used to get around 1200 Mbps (Tx/Rx) at a distance of one room from the router. Now, at the same location, the speed drops to around 840 Mbps.

A similar pattern is observed on 80 MHz as well, where the speeds at the same distance are lower than before.

Even on the 2.4 GHz band, the range has significantly reduced, and the signal performance is noticeably weaker compared to earlier.

 And the topology is isp onu 2.5 gbps port ( bridge  mode ) ---- ax 53   Main ------- ax 12 in ap 

Additionally, QoS behavior appears inconsistent: while upload latency is now stable and well-controlled, download latency still shows spikes and higher jitter under load, suggesting that download-side QoS or queue management is not functioning properly

My friend, when I use 160 MHz, the 5 GHz SSID does not appear on my iPhone 14 Pro Max, Samsung Galaxy Note 20 Ultra, or any of the other devices at home. I’m not sure why it doesn’t support devices that operate at lower bandwidths (those that don’t support 160 MHz).

I’ve tested several units, and the results are the same in every case. However, with my UniFi U7 Pro Max access point, when I set them to 160 MHz, my phones that don’t support 160 MHz can still connect automatically at 80 MHz, even though the channel is set to 160 MHz.
