No internet connection avalible

I have a Sony Vaio imported from japan. It was originally ment for windows 7, but when I bought it, it was running windows 11.

I decided to downgrade to windows 7 ultimate just because lol. I used a reinstall action disc because I thought that's what you should use for a laptop that already was meant for windows 7.

my "disk partion 1 system" didn't have enough for me to install it, so I used disk portion 2 (primary I think?) which had enough to install my files

it's all working well and good, but it says "no connections are avalible" on my laptop.
I've tried everything. I tried using a USB to transfer files that were supposed to work onto this laptop and STILL nothing has changed.
my laptop isn't set to wireless, i tried that already too.
admittedly, i kind of regret this, especially since i have no idea what i'm doing.

(sorry I'm new to this website I'm not sure if I'm replying correctly)

there are yellow triangles on "other devices", I'm not sure how to check disk manager because I can't find it?
the wifi used to work completely normal with no issues on windows 11, I don't know what's going on.. should I buy a new disk? if so, what do you suggest?

i didn't take any previous pictures since i didn't think i'd have this issue..
can i still use this UK version if i live in the US? just want to make sure.

oh, also how can i look up my laptop on the link you sent me? i have a sony vaio and tried looking it up and see numbers next to some laptops. where can i find the number for mine?
