I’m a bit confused about what the problem is you are facing. The subject of your post mentions that circle-r reset is not working but the other post you quote is about pcie reset.
Hmmm maybe more to this… while arguing with CUPS, I rebooted the machine (shutdown -r now) and wifi/WLAN would not come up. Everything present, just wouldn’t talk…
I did shutdown -h, then Circle-0 then -1. Rebooted, and WLAN worked right off.
