Yes, I don't go to those so-called cafes anymore because I know the owner will never throw away expired items. Even places like M..hatan Fish Mar*t is shitty now. Just check the kitchen
Yea go for wifi 6. I'm not that techi to explain but coverage is good and stable. What I do is Fiber > Then use this as the router .
Custom will hold but then you have to get the frequency licence from TRCL. You can do it through email. DHL will help.
