I just picked up an RT-AC86U for my main router to replace my RT-AC87U (driving factor was better VPN performance). Like a dunce, I planned to make my 87U the repeater but didn't realize it doesn't have repeater mode so here I am. I am doing video streaming for all of our TVs (Netflix/Plex server mainly) and the furthest TV struggles sometimes with buffering in Plex so I think a repeater would help. I have no ethernet ran though my house and would like to avoid it. I'd also like to have a single SSID that our devices can hop around easily as we move though the house/outside. If there is any way to use my 87U that'd be best (seems like it would be ethernet backhaul and seperate SSIDs in AP mode, both which I'd like to avoid) or what would be the most cost effective repeater? I considered picking up a second 86U, but wasn't sure if a cheaper RT-AC68U would serve me just as well since that wouldn't need the higher powered CPU for VPN encryption. I've also looked at the Lyra pucks (but can't find where to buy them?) and Blue Cave which seem interesting, but maybe gimmicky.
