RT-AC5300: Devices on 2.4Ghz AP can't communicate with devices on 5 GHz APs

[smhollingsworth]

I've tried Asus tech support about this, but they were no help. I kept losing connectivity with some devices on my network. Seemed really sporadic and couldn't find any pattern between what worked and what didn't. Eventually, I realized that anything connected to the 2.4Ghz AP could not communicate with devices on the 5Ghz AP. Everything on the 2.4Ghz AP can communicate with anything else on the same AP and devices on either 5Ghz AP can talk to anything else on either 5Ghz AP. AP isolation is not enabled, so it isn't that. I've dug all through the interface and can't find any setting that seems to be causing this.

Firmware is 3.0.0.4.380_7743-g2cf84e9

Any ideas?

Try the following commands over SSH:

nvram set wl0_ap_isolate=0
nvram set wl1_ap_isolate=0
nvram set wl2_ap_isolate=0
nvram commit
service restart_wireless

Just in case the AP isolation setting shown on the webui might not be accurate.

That seems to have fixed it. Thanks!!
