I wanted to post this incase some people didn't know, but:
They have these "Mesh" WiFi routers called Eero and they are like $500 and you get 3 units, that bridge in their own special way, meshing.
Honestly tho, on a budget, and lowendmac style, you can get an Airport Extreme 4th Gen or 2nd Gen, for basically $25 a piece shipped!
But here is why a 68Kmla cat, might want to do this. WPA, WPA2, WEP, etc
I forget right now, but on OS9 with a Wifi card it isn't FRIENDLY let say with WEP for sure on a 4th Gen, so if you have just a 4th Gen you can't lower the security unless you just have NO security if you want OS9 to connect (This is in Airport Utility macOS Sierra), but if you have say 3 x 4th Gen, in your OWN Bridging design and then ethernet to a 2nd Gen, making it's own 802.11b/g you can still setup WPA for OS9 (2nd Gen), I mean it's low security but...I make mine private/hidden, so it's not visible.
But you can get 3 x 4th Gen and 1x 2nd Gen for $100 STRAIGHT. If you can live with 802.11n, and b/g for old stuff eBay is A SICK ASS way to go vs Eero...
Plus compatibility with ALL your Devices...
Good Luck Out there...
