KP200 -- Unstable WiFi Connectivity
Problem Details
- First floor remodel started November 2020, finished May 2021.
- All TP-Link hardware originally configured May 2021.
- Wired and powered up weeks before that.
- Scheduled Christmas lights for sunset to 12:30 AM:
- Scheduled using Alexa routines.
- Scheduled in groups of three (3) with three (3) receptacles in each group, 2 minutes apart.
- Each group scheduled a second time 8 minutes after first scheduled time for improved reliability.
- Everything is working great from Thanksgiving on!!! Happy Wife! Happy Life!
- Electrical work on Dec 16th requires breakers to be turned off.
- Electrical work completed same day, breakers turned back on.
- Since then, all KP200's connect to the WiFi but do NOT maintain connection:
- Solid white WiFi status light for a minute or so
- Begins green blinking WiFi status light until connection is reestablished.
- Rinse and repeat.
- Just the KP200's are not communicating reliably -- all nine (9) of them.
- Everything else works as designed as it has for the previous seven (7) months.
- Results: highly unreliable control of Christmas lights -- sleepin' on the couch... :(
- This is NOT a local/remote control issue:
- If the receptacle can't communicate on the local network, no expectation of remote control.
TP-Link Smart Devices
- Nine(9) KP200 Smart Plugs -- the problem
- Hardware: v1.0
- Firmware: v1.0.9
- Six (6) HS200 Smart Switches
- Two (2) HS220 Smart Dimmers
- Two (2) KL110 Smart Lamps
Miscellaneous Networked Devices
- Xfinity XB7 Cable Gateway (aka Technicolor CGM4331COM)
- Three (3) Ring Model 4 Doorbells
- Four (4) Laptops
- One (1) Sony Smart TV
- One (1) Roku 4K Streaming Stick
- One (1) landscape lighting controller
- One (1) Crestron Pyng hub for shade control -- hardwired
Failed Attempts to Correct
- Assigned DHCP reserved IP addresses in the XB7 Gateway to all TP-Link devices as well as Ring, Crestron and Roku devices for good measure.
- Reset XB7 Gateway.
- Reset all KP200's to setup mode and reconnected to WiFi through Kasa app.
- Factory reset the two (2) KP200's closest to the XB7 Gateway, reconfigured, and reconnected to WiFi through Kasa app.
Network Diagnostics and Additional Details
- XB7 Gateway confirms devices have IP addresses matching assigned MAC addresses.
- ping assigned IP addresses -- all devices EXCEPT KP200's have rock solid responses.
- arp table shows no duplicate IP addresses.
- Closest KP200's are 15 ft from XB7 Gateway across an empty room.
Help! I want to sleep in my bedroom again by Christmas Eve so Santa can deliver those sweet, sweet gifts...
Reasonably technically savvy. If you have additional science that can be applied, I should be able to provide additional diagnostic information.
