Thank you for your response, I do appreciate your input.
However, if you weren't trying to be rude, you kinda failed. I didn't actually ask anyone for advice on how to sort out my setup (though advice supplied is always gratefully received), what I actually asked for was if anyone knew of any useful guides on how to learn how to set things up.
I was asking how to learn, not to be told how to write a better support ticket.
To address your reply further; how much information could I have provided that would have been enough for you? You even ask for information on my router (I use a TP-Link mesh network, if that helps. It streams my partner's PC beautifully), on what planet would I have known to tell people that when asking how to learn?
But as I said, I do appreciate your input, and you have imparted some useful information. Thank you.
