Like Nuhi stated, you have a ton of reg files and bat files in your image. If these tweaks are all active at the moment then that's probably the issue with your downloading. Some of those files are likely disabling functionality required to connect. I would do a clean install of Windows without all these tweaks and then download the latest NTLite and make your newly updated image that way. Your router is another source of firewalls too, so check that if you haven't already.
On a related note, I see several red flags while browsing the tweaks you integrated. Based on the naming scheme it looks like you grabbed a bunch of stuff from the internet and blindly applied them. Some of those bat files can also be deleted and turned into registry keys that can be integrated instead, which is better than doing it post-install. Also, be aware that quite a few tweaks may no longer work when you update from 1507 as many registry keys changed over time in W10, and this concept applies in the opposite direction too--using tweaks meant for 21H2 or 22H2 won't necessarily work on 1507, so you have to test each individual tweak before integrating them.
