They have their own system. I have to ask you to ask them how to solve this. It can't be an unique request.
Hi All,
I live in a housing complex that provides a WiFi connection and/or a single ethernet line. I want to create home network for gaming, file sharing, my home security cameras, etc, but am unable to do so. Also, I'm not a complete networking beginner.
However, I can't simply connect a router to either the WiFi or the ethernet. The ISP requires certificate authentication for each device on WiFi (and no devices see each other). In order to connect the single ethernet line, you have to provide the MAC ID of the single device. Routers are not able to be connected. I can't find a way to login with them.
Another option I considered was a virtual WiFi router from Windows 10. So, I connected my PC to the ethernet, created a virtual router and thought I'd be in business. However, something is set up to recognize when you use a virtual router or share your internet connection. When this happens, the internet connection is killed.
This is driving me nuts. I know there may be additional details needed, but I'm hoping maybe ya'll can help me through this.
Thank you so much in advance.
