Just sign out and remove all the youtube cookies and the adblockers still work just fine. Sign in when you want to comment or use another browser that is signed in and never watch the video on that browser. Simple solution. Another option is watch the video by right clicking and opening in a “new private window” instead of watching while signed in. That works really well until you want to comment.
I’m using TP-Link Omada series access points and they are amazing. You can run them off of a power brick or POE (power over ethernet) and put then anywhere that you can run ethernet. They can also work in mesh mode if desired and are not super expensive. Combine them with the OC200 controller or run the controller software on an always on PC and they work flawlessly.
You can pick your preferred wifi version and upgrade to a newer version later on by just changing out the access points and adopting them into the system.
