My ISP modem/router is connected via powerline to a second router. On second router (AP) I have disabled DHCP, I have connected it with powerline using the LAN port (so not the port marked as internet going to WAN). I set the AP LAN IP to be 192.168.1.99 ( the main router is 192.168.1.1).
I have not made any setting changes to the main router.
Currently I have given my AP the IP of .1.99, which in practice means it should never be a problem, as we wont have that many devices connected. Although I was wondering if its possible to make sure that the 192.168.1.99 will always be reserved for it and not given out. In theory the routers will always be connected so this should not happen I guess, but still want to be safe
Also, is there a way to test which AP I am currently connected to?
