that would indicate an old version of NextZXOS? Are you on the latest?
I have the same issue. N-GO board, all latest NextOS and firmware. On all bauds. Even tried the .espbaud -dfR 115200 command. And multiple retrys by cold booting consistently having this issue. I had not got a chance even once to load the program fully yet. Always freezes at the "checking wifi" after a bit of loading.
