AXE75 6GHz Low Power
The output power on the 6GHz band seems very low compared to 5GHz. I'm streaming to a Quest VR headset with the router about 10 feet away, nothing in between. Despite this, the Quest shows the network at only 2/3 bars, and the connection speed bounces between about 1400-1900 Mbps instead of the full 2400 Mbps. On the 5GHz network it always shows full bars and 2400 Mbps.
Using my phone at the same location I checked the power with a wifi analyzer app. It shows -45 dBm for the 5GHz network, and -67 dBm for the 6GHz. That's a huge difference! I've tried different channels within the 6GHz band but don't see any improvement.
One interesting thing I noticed is that changing the power for the 6GHz network from "high" to "low" in the router settings doesn't appear to make a difference. It's like it's stuck on "low" no matter the setting.
I'm in Canada, in case there's some regulatory issue that would be relevant.
Interesting. You linked the US model but mine is the Canadian, which had no available update when I made the post. But now I see 1.3.2 has come out for the CA version. I think it came out the same day I made the post, or 1 day later! Coincidence? Probably.

However the notes for this version don't mention wireless performance. I tested it and there's no difference.
Here's a screenshot from the Wifi Analyzer app on my phone showing the issue (network names edited out). This was taken with the phone right next to the router.
