Networking nerds, give me home LAN upgrade advice!
Current situation (needs are in post #2) is as follows:
I have 1000/25 internet now, and my R7000 FreshTomato router + WiFi AP only supports that WAN speed if I overclock it to 1.2GHz.
A Cat 5e run connects that to an Asus RT-N66U at the opposite end of the house, which acts as a secondary AP+switch.
These are both downstairs, but we have a second floor. The kids complain about unstable WiFi upstairs.
