I don't think I've set up my home network correctly because i'm having loads of issues that come and go.
I have a BT homehub.
I have an ethernet cable running from it down to my garden with a TPlink Archer C50 router providing wifi.
All was going well until:
I added a second TPlink router in my house to extend my bad signal there.
I first ran another ethernet cable through my house and set up the new router as a range extender.
Then all my alexa devices started dropping off the wifi to the main BT hub.
So i removed the ethernet cable and used it as a wifi range extender.
this was better but i often get errors: can't connect to (new) router, or new router has no internet.
i assume there's some conflicts in there somewhere?
hope someone can help me as i'm likely just being dumb to network stuff.
