Random stubborn Deco XE75 being weird with devices
I have 3 Decos. XE75 is primary with a X20 and X55 as remotes. I have a reboot schedule weekly. As of right now, I have 80 clients connected. A majority are IoT (Wyze cameras, Light Bulbs, Switches, Plugs, etc). Most of the time things are fine, but randomly, I will have issues with some IoT devices not being able to connect. Sometimes my TV (Samsung S90C) won't have internet, but the Deco app shows it as a connected device. Tonight, however, my PC suddenly doesn't have connection. Deco app shows it as offline. These things are always resolved by a reboot of the Deco, not the individual decives.
My question is, why does this happen? I set up the reboot schedule because before, it could be 2-3 weeks before my network goes wonky and my IoT devices end up offline. But, even with a reboot schedule, things get weird after a day or 2, but not always. I haven't had issues in months. Is there anything I can do to mitigate this issue other than setting up daily reboot schedules??
Things I have tried include using Connection Preference on the IoT devices to keep them on 1 device and leaving the mobile devices to be able to roam. I use the High Priority setting for important devices like phones and computers. The only settings I haven't used are the IoT Network and Device Isolation. I set the Bandwidth information to what I get from my ISP. QoS is on. Not using VPN, Static Routes, IPTV, DDNS, Fast Roaming, or NAT Forwarding.
Thanks for any help.
