#84607 I'm wondering if one of my ESP8266's has been bricked. After loading a program, the device shows no network activity on either Wireshark or Microsoft Network Monitor. I first noticed the problem when I discovered that calls to "WiFi.hostByName" kept returning "(IP unset)". To check the program, I loaded it into two other ESP8266's. In the other devices the program worked without error. Has anyone had this happen before? Is there a fix or is the device just trashed?

Thanks.

#84689 I later found that I also could not ping one of the specific host addresses I was using.
Clearing the DNS cache and restarting the router seems to have fixed the problem (at least for now).
