No problem, also look at [email protected]’ comment in reply to mine. They have some info I wasn’t aware of regarding tri-band WiFi routers. I’m living in WiFi 5 land, so I wasn’t aware of this cool trick:
His router is tri-band though meaning it has 2 5ghz transceivers. With an extender usually you use one of them as a backplane for ap->ap communication so it doesn’t interfere with your performance.
So an access point is still a good solution, but it sounds like you can use it as an “extender” without an ethernet cable as long as you can use one of your spare 5ghz bands to communicate with it. Which is super cool and I was totally unaware of.
