1.13.2
wireless modems attach but computers cannot detect that its even there.
no peripherals attached or everything but wireless modems attached. tried opening wrapping and nothin.

1.12.2
so my resolution was i went back to older version because i wanted to use this feature.
i achieved my goal for the most part but also seen in YouTube videos and experienced for myself.
when changing output for redstone to on or even changing colours and text on monitors it need a block update to apply like breaking a sand block for the rest to fall.
to allow it to turn on my redstone i had to break it and place again and same when turning off. major inconvenience when the idea was to some degree automate it.

1.14
attempted to use in 1.14 but game crashes with the later fabric installed.

Can you include your logs and mod versions? I'm fairly sure several of these bugs have been fixed at the latest version.

Well i just got the latest version of 1.13.2 which has a fix for the the wireless modem and the 1.12.2 block updates. But i havent tested 1.14 again since earlier today. I tried the latest 1.14 version of cctweaked, the fabric mod loader worked fine but the moment i put the mod in it crashed. I will test again on the weekend and send u through the logs if you like? I havent used fabric before ive just been using forge and honestly i just was writing few codes and dont mind not being on the latest mc version. Its a great mod. So great work man

I just saw that the CurseForge page has a new version that the one listed under "releases" in this repo.
https://minecraft.curseforge.com/projects/cc-tweaked.
with this version minecraft at least does not crash and ModMenu shows the CC-Tweaked as loaded.

EDIT:
Verified that I can now craft computers
