I presently have two Airport Extremes (I know not what generations, but one of them has 5 GHz) and 30 Mbps internet service. What I find is that my internet speeds degrade over time until I reboot the AEBS that is attached to the cable modem.
I require one of the routers to extend the other's wireless network.
If I bought the RT-N66U to connect to the cable modem, will it allow an AEBS to extend its wireless network?
