Problem: My smart switches/plugs (TP-Link Kasa) won’t consistently connect (they only reconnect about half the time) to my Tenda 1200 AC10U router after a scheduled nightly maintenance reboot. I have found that if I unplug the router for 10 minutes (2 or 3 minutes doesn’t work) and restart the devices, all connect normally and function normally until the next reboot. When failure to connect occurs, all the smart devices fail to connect. Currently, I have just disabled the nightly reboot.
I am using 32 smart devices – all light switches and plugs and all on the 2.4GHZ band. I have no video or other high bandwidth devices connected to the 2.4GHZ band. There is no less than 2 bars of signal strength on my iPhone at the switch locations furthest from the router – even the switches in the same room as the router won’t reconnect. All other internet connections in my home are either wired or on the 5GHZ band and they do reconnect normally after the reboot - except for an Echo Dot (5GHZ). I have to manually reset the Echo Dot although the Echo Studio (5GHZ) always reconnects.
I have the 2.4GHZ band on channel 11 and the 5GHZ band on channel 153. Most router settings are default. My Tenda firmware version is V15.03.06.49_multi. All switches and plugs have been updated to the latest firmware. I do not know if the problem is with the smart switches/plugs or the router and both TP-Link and Tenda support was emailed. I will update if and when I hear back. Can anyone offer any advice?
Thank you in advance for your assistance!
