[R3 v4.0.1510] Wi-Fi performance regression on PS5 Pro

[TamasN]

 

Hi Netduma Team,

 

I would like to report a Wi-Fi performance/stability regression introduced in firmware version v4.0.1510 on the Netduma R3.

 

Setup details:

- Router: Netduma R3

- ISP Modem/Gateway: FRITZ!Box 7530

- Primary Client: PlayStation 5 Pro (connected via 5 GHz Wi-Fi)

- Placement: R3 is on the ground floor, PS5 Pro is on the first floor almost directly above it.

 

Issue experienced on v4.0.1510:

- After updating to v4.0.1510, the Wi-Fi signal quality degraded noticeably in DumaOS, and frequent in-game "unstable connection" icons and ping spikes occurred on the PS5 Pro.

- Troubleshooting steps taken on v4.0.1510: Performed a full Factory Reset, deleted and re-added the Wi-Fi network on PS5 Pro, adjusted antenna angles, tested fixed channels (36–48) and forced 20 MHz / 40 MHz channel widths. None of these resolved the ping spikes or signal instability.

 

Workaround / Resolution:

- I downgraded the R3 back to firmware v4.0.1147.

- Immediately after the downgrade, Wi-Fi signal quality and connection stability fully restored. The PS5 Pro shows 100% signal strength, and all in-game ping spikes and instability warnings completely disappeared.

 

This suggests there may be a Wi-Fi driver or RF power management regression in v4.0.1510 affecting 5 GHz penetration through floors/walls.

 

Hope this data helps with the next firmware build!
