iATKOS | United Kingdom

I'm trying a first time clean install of the latest OS. I downloaded oclp, made a bootable usb drive with enough GB and tried to install it onto a ssd that I connected with usbc (old hard drive is way to slow, I ran the older, supported versions on there for speed and performance reasons, worked good) I erased the ssd for clean install, selected the efi boot logo and tried to install the OS. First everything seems fine, Apple logo, loading bar, even the sequoia 29 minute below the bar appear, but suddenly it goes black after a while and goes back into boot menu.. I've tried it with a slightly older version of sequoia as well, same thing.

Imac can't connect to the WiFi (see picture), it says connected, but no internet which is weird, when I click on the WiFi logo I can't see the name of the internet and there is a logo over the wifi icon

I don't know what's going on
