ESP 32 beta loss of WiFi connection

Hi I have two of the esp 32 with same software one is a Chinese version of the 32 and the other one that glyn sent me to try . These seemed to work fine for two weeks when I was self isolating . But since I have returned to work I am finding that I am having to power off both of them every few days . As they will not let me connect to there web page. And also they both now display in the demand shaper as not contactable . Before software upgrade they did seem to keep communication with the demand shaper . It is interesting that both units are giving problem as one is not being used a lot as the wife’s car is locked down with her and the kids . I did fit some surpressors to the contractor coil connections
But these do not seemed to make any Diferance
I will try what you have done next time I have problem and see if I can get them back by taking them of network . I was wondering if I could port the code to a aurdino device with hardwire network port
As I don’t need them to be WiFi .
