Hi Fraser,
Thanks for the advice! I always keep my Wi-Fi bands separated and stick to 5GHz for the PS5 Pro since the ping is way more stable for gaming.
I reinstalled v4.0.1510 today and did a factory reset, then put both bands to the test while playing Battlefield 6 with two devices streaming video and a third downloading a torrent:
- 2.4GHz: DumaOS showed 'Excellent' signal and the PS5 hit 94-96%, but the ping spiked all the way up to 160ms and I couldn't get it to stabilize. I even dialed Congestion Control down to 10%, but it didn't help under that load.
- 5GHz: Signal status in DumaOS fluctuates between 'Very Good' and 'Excellent' (PS5 shows 100%), but with Congestion Control at 60%, gameplay was rock-solid—zero ping spikes and zero packet loss under the exact same load.
I originally suspected a Wi-Fi issue because on v4.0.1147 the signal reading was consistently 'Excellent' across all devices. On v4.0.1510, the signal reading started fluctuating, and I had ping spikes alongside those drops previously. Right now, despite the visual signal fluctuation in the UI, gameplay feels completely smooth on 5GHz. I'll keep monitoring performance over the next few days and let you know if anything changes. Cheers!
