Archer AX6000 devices randomly stop receiving pings from other devices on my network
So I've had this unit since about Black Friday as amazon had an amazng flash sale and I needed a new router. The setup went well and the throughput has been fantastic.
I am having one issue that I can not for the life of me fix. I have the router set to reboot daily becasue of this issue and short of hard resetting the router I can't get the issue to stop for more than 24 hours.
The issue is that certain devices can not communicate with other devices on the network for certain tasks mainly casting to my VIZIO television and in some cases printing to my wireless canon printer (firewalls have been checked and are not blocking connections as this works for about 14-16 hours and then stops). Devices randomly stop replying to pings after seemingly random periods of time on my wireless network and I don't have the AP isolation feature enabled nor ANY of the "HomeCare" features on. I do have ONE ssid shared between the 2.5/5GHz bands with smart connect enabled. I thought maybe the devices were having issues comminication over different radio bands, but that isn't the case. Just tonight I was casting commedy from YouTube to my TV and when it ended I wanted to queue up another show. I couldn't because the TV no longer showed up as a device available for casting from Chrome.
I power cycled the TV (but it was clearly online and able to get to the internet). I also rebooted my laptop with no luck so I tried to ping the TV from my laptop (both the laptop and TV were on the 5GHz band so this should work) no reply from the TV and the requests just timed out.
I figured OK, I guess I need to reboot my router, and that fixed this instantly. Does anyone have any idea why this may be happening? It is driving me bananas because other than this and some issues with DNS resolution failures with IPV6 enabled the router has been pretty solid.
Edit: It may be that devices aren't communicating properly over diffreent bands. When I checked again the laptop was on 2.4GHz and the TV was on 5Ghz. Still SmartConnect is on so shouldn't the router be treating them like one SSID?
