Mac Os Lion reinstallation

I had recently updated my MacBook pro 2011 from Mac os Lion to Mac os Sonoma and immediately after the installation some features were cut out like Wifi etc. I wanted to downgrade back to Mac os lion but ended up erasing data on both my utility disks with the hope of deleting the sonoma software then reinstalling the Mac os lion from scratch but it keeps on popping an error message on the verification page when trying to reinstall the operating system. Please help thank you in advance.
