At the age of 77, I installed OMV on my Raspberry Pi 4B equipped with the original and fully updated Raspberry Pi OS. I did this by the command: "wget -O - https://github.com/OpenMediaVa…Script/raw/master/install | sudo bash" which was done without any error.
This installation has destroyed my wifi access and shows the error "Connection to dhcpcd lost" with the network icon in the top right corner of the screen and it is no longer possible to repair the connection from there.
I understood from the forum that OMV had installed its own network settings and that the solution had to go through OMV and probably through the System/Network/ page and its Wlan0 line but I don't know how to configure this line correctly.
Thanks for any help available to a beginner.
