I have a current set up of two Asus RT-N66U routers. One performs the function of router/gateway/dhcp with radios off, the other handles the WAP duties.
Tl;Dr - - my n66u 2.4g channel disappears after activating the ac66u with matching ssid, security and psk. I set them to operate on n-only and n/ac respectively with b/g blocking on both.
#1 RT-N66U: Router mode w/dhcp on, radios off
#2 RT-N66U: AP mode with 2.4 and 5 radios on; guest network active on both radios for the primary connection. Connected #2 lan port to #1 lan port.
It all works great as is. My only issue with this configuration is that the peak number of users has outgrown the AP's ability to sustain all simultaneous connections, thus at peak times randomly kicks users off and on. To solve this, an Asus RT-AC66U was obtained to help balance the load.
Enter #3 RT-AC66U: AP mode with 2.4 and 5 radios on; guest networks are active on both radios for primary connection like #2. Connected #3 Lan port to #2 Lan port.
For privacy, xxx and yyy are used as variables to mask. SSIDs and PSKs of both match for seamless connection without users needing to connect twice. Guest networks are required for our general users to protect user privacy.
In general, we are on a /24 subnet with each router assigned static ip x.x.x.1, x.x.x.2 and x.x.x.3 respectively. Dhcp doesn't start until x.x.x.10 to allow for certain devices.
Set radio configuration on #2:
2.4g: ch.11, 20/40 width, n-only, block b/g on, ssid "xxx", psk "yyy", Auth WPA2 personal
5g: ch. 142, 20/40 width, n-only, ssid "xxx 5", psk "yyy"
Set radio configuration on #3:
2.4g: ch.3, 20/40 width, n/ac, block b/g on, ssid "xxx", psk "yyy", Auth WPA2 personal
5g: ch. 36, 40/80 width, n/ac, ssid "xxx 5", psk "yyy"
After changing all settings such that they should play nicely together, I restarted them both. Once they come back up, the #3 AP works exactly as expected, survey shows both bands running.
This is the problem - - The #2 AP ch. 11 2.4g band is gone as viewed on wifi survey app. #2's 5g band is broadcasting fine. In the router's wireless config panel the only radio I can choose is the 2.4, but all my other settings are for the 5g range like ssid and channel.
I can ping the internet when connected to only the #3 router and vice versa, not really a required test but did it anyway FYI. I've started from scratch several times and every time it does this. I'm not sure that it's even an issue with the majority of devices being dual band capable now. It mostly just bothers me because with two dual band routers I should get two dual band signals on opposing channels.
Anyone know anything I may be missing with the quirks of these two devices operating together?
