I have 4 apartments adjacent to my house (200' LOS), and only 30mb/s internet to share. (I live in the boonies.) I want to keep any of my guests (each with multiple devices) from sucking up all the bandwidth, by limiting them when there is demand from other guests, or limiting all when I want data. I also want to separate the users from sharing data. Perhaps, the router might have 4 guest ssids and passwords? Is there a router that can handle this? I really don't want tobury 4 ethernet cables to 4 APs. Suggestions??
