The two APs are on independent platforms. We don't have Unleashed for 7982, so it will be the same as having two Solo/Standalone APs.
No problem though, if you connect to the same home LAN that has an ISP router providing DHCP, but your clients will have a brief re-connect
blip if/when they roam between APs in different parts of the house. You can decide if you want to run Unleashed on the R600 (maybe nice to
get familiar with the WebUI if you plan to expand, as Unleashed supports Mesh too...), or in Solo/Standalone mode which will look just like the
7982 AP interface.
