The Wi-Fi performance is quite unusual.
I experienced some network problems before fixing them, but after resolving them, I tested my connection again. I used Ookla and Google speed tests on both my phone and my desktop. The phone got 380MB/s out of 400MB/s, while the desktop achieved 120MB/s. Both devices were in the same room and position, yet the phone's speed felt much lower than expected. It seems the desktop likely has better hardware or network settings, even though it’s more powerful.
My adapter is a TP-Link AX3000. It seems to support Wi-Fi 6, though I’m not entirely sure about the advantages or drawbacks. I don’t know what modem or router I’m using—it’s an Xfinity/Comcast XFY1 model, and I haven’t upgraded to a better third-party device. Regarding the other questions, it looks like the main differences come from the Wi-Fi chips or processing rather than major changes. All tests were conducted in the same room, with similar conditions. Even when positioning my phone on top of my desktop and adding obstacles, the phone still achieves nearly full speeds while my desktop drops to about a quarter of that. About five minutes ago, my connection was unstable, dropping from 150 Mbps to 20 Mbps or worse within an hour. I might need to consider a different router... It didn’t seem worth the effort to change it.
Identify the device you're using or check the label directly. Only the xFi Advanced Gateway (3rd gen) supports WiFi 6. Mobile phones typically have stronger antennas than desktops. Which device was tested for the wireless survey? What settings are active on the gateway? Also, is the xFinity WiFi Hotspot enabled?
Things settled down unexpectedly. I experienced some instability for a few days without clear cause. Then both my PC and phone reached near maximum wireless speeds during testing—probably due to a firmware update sent to the router. Those updates likely introduced a few bugs, and after some troubleshooting by Xfinity, the issue was resolved. It might have been related to GPU issues or something else entirely.
