Hey, I recently purchased a Tri-band asus RT-AC5300. I updated the firmware to Merlin today, and I am now noticing that i cant see the 2nd 5ghz band at all on any device. When looking into the WIFI settings, the control channel can either be set to AUTO, or 0. neither of these fix my issue. Also when going into the WDS tab, there isn't a MAC address entered for the 2nd 5ghz band. When i first got this router i want to say that the stock channel for this band was high, somewhere around 80 or 90 i think. Is this a known issue with this router/firmware combo? I cant find any info on this at all. Thanks
