AX6000 keeps dropping 2.4ghz channel
I have had the AX6000 router for almost 3 years with absolutely no issues. About 6 months ago I decided to change all the switches in my house to smart switches. So now I have around 30 iot devices connected to it, 95% of which are Kasa switches. But ever since I added all these device the router regularly drops the 2.4ghz channel requiring a manual restart. And a few times the router has completed dropped all connections, 2.4ghz and 5ghz.
I need help with this issue. Can this $300+ router not be powerful enough to handle 40 devices, (iot and PCs)? Is there a setting I need to change? I already tried isolating specific channels and frequencies, but that didn't help.
