Not seeing any change between 17.0.3 and 17.1 when it comes to WiFI.
That does raise an ongoing question.
My WiFi supports 6 and 6e at 1GB down, 50MB up.
The speed on my 15PM is pretty much always < 500MB down and < 40MB up.
The speed on my S23U is pretty much always > 500MB down and close to 50MB up.
Why is the 15PM so much slower?
No issues here on my 15 PM, my internet speed is 1.1Gbps down, 110Mbps up and the 15 PM on Wi-Fi 6 (not E as my router doesn't support it) on my Netgear RAX200 router is pulling 1168Mbps down, 101Mbps up. This was on 17.0.3 and 17.1 RC.
Looking at link speed between the 15 PM and my router its connecting at 2.4Gbps, so plenty of extra speed I could squeeze out of this if my internet was even quicker.
