Hi @erik1, There is also a sd card inside the Pixhawk. Is your issue that the internet is not detected? Have you tried another wi-fi to test, like a phone hotspot? ---

That is very odd. Is this after flashing the 0.0.18 image to the sd card? IS you Raspberry Pi the 3 B version? We don’t currently support the 3B+ ---

Ok, I need help to understand what is going on. A few questions: 1. When did the problem start? 2. What were the circumstances? 3. When was your companion software updated/installed? Did you try re-flashing it? 4. What is your browser? The CSS seems to be behaving weirdly. Try chrome/firefox to make sure it is not something specific to your browser. 5. Have you tried anything else? It seems that something could be wrong with your companion installation. The straight-forward solution would be taking the sd-card in it out and flashing a fresh copy of the [latest](https://www.ardusub.com/resources/downloads.html) companion image. ---
