Thanks dark_pyrro, I spun up a RP to reflash the Mk7 with 1.1.1 A couple of notes after I did:
- I set up without the 5Ghz adapter connected this time.
- I set up with radios disabled over the USB-C connection to the RP, and uploaded the bin as opposed to OTA.
- 1.1.1 seemed more stable but the UI still felt laggy to me. Maybe I'm expecting too much but it felt slow and clunky.
- Client mode worked correctly but there is a bug if you enter the wrong network password, it says connected and spins endlessly. When you do enter the right password, it connects but doesn't refresh, you need to refresh the entire UI to see if you got an IP address.
- Internet connection was a little buggy once connected, I could list modules but then a moment later I couldn't, even though client mode wasn't changed.
I then updated to the 2.X beta and it seems more stable, but overall I'm not impressed with the device, it just seems 'off' and I don't trust it to be reliable as it's given so much trouble to even get it going. If there is any way to test or verify the hardware, I'd be interested in learning more as I'm now convinced I have a duff board.
