EZ-B V4 No Longer Connecting, Shows Firmware 0000000

Please see below the logs when trying to connect from connection diagnostics

How do I fix this? It was working perfectly until today

Does the ezb make the startup sound when power is applied? Why does the IP address in your log keep changing from 192.168.1.1 to 10.10.10.10?

Did you read the diagnostic connection info about firewalls and virus scanners?

#2   — Edited

I connected first straight to the EZB access point, then connected in wi-fi mode and test again. Firewall and anti-virus both disabled. Was working perfectly until powered today and had this issue. I disconnected the EZB speaker (needed the space) so not sure about booting sounds from the board

DJ thank you for your prompt response. After resetting EZB multiple times, I was able to connect to it and updated firmware. Seems to be working fine again

Thank you

Thank you. It is resolved but once in a wile I get this disconnections and does not allow to reconnect until multiple tries. I will let you know if it keeps doing it. Thanks for your support
