That does seem pretty quick
@BrandonS MR45 is still happily on sale, perhaps there is a warehouse of stock to shift...
To be fair I have an MR55 and it works fine unless you have Intel WiFi5 chipsets with power saving enabled.
What about MR45? I thought I read somewhere MR45 and MR55 both shared a "troubled" chip set or internal firmware of some sort?
I'm going to get the direction wrong, so fact check me, but the MR45/55 were pre standard and didn't support either up- or down-stream MU-MIMO which is a hardware limitation.

That affects all of the WiFi6 APs that issue.
@PhilipDAth I haven't seen it yet on an MR56 but the laptop that was most affected now has an AX200 card in it so that's fine. I'll double check with a remaining one to that was quite bad with the MR55. Perhaps it was the update from 27.4 to 27.5 that helped?
the 45/55 used the “Hawkeye V1” chip from Qualcomm, also known as IPQ8078/8074.
These were followed by the second version of these chips, which were rebranded as Qualcomm Networking Pro. The official advertised difference is mainly that the second version does UL-OFDMA and UL-MU-MIMO.
With that said, other vendors have struggled with enabling many WiFi 5 features: 160MHz, DL-MU-MIMO, AP to client transmit beamforming (the receive direction works), and more. That leads me to suspect there might be more that is immature or problematic about these chips and it’s not just a matter of only supporting DL-OFDMA.
