Yup. It is really bad.

Where I live, the channels 36-48 - which is really just one channel once you go 80 Mhz - is chock-full of networks and completely unusable. The DFS channels are also complete unusable, because they jump around like crazy due to some noise source (I checked, and there's no radars around). Trying to use them means you see disconnects ten+ times a day.

My router can use channels 149+, which are not DFS and most consumer routers don't use them so that part of the spectrum is clear, but those channels have smaller allowed broadcast power so I get slower speeds. Or I could use 2.4 which works reliably, but is even slower than the low power 5 Ghz channels.

Interesting consequence is that while my ISP started offering gigabit connection, I see no reason to upgrade, since my Wi-Fi is now the limiting aspect, unless I start using wires or replace my devices with ones that can do Wi-Fi 6e or something. Even the 300 Mbps I pay for I only get in the living room.
