Model: TL-WPA4220 KIT  
Hardware Version: V5
Firmware Version: 1.0.1 Build 200811 Rel.68784n (6985)

I am using 4 TL-WPA4220 extenders to create WiFi in the house (3 floors and garden) and a TL-PA4010 to feed the signal to the grid, located very close to the router. Since approximately 6 weeks I experience random loss of WiFi (once or twice a day). (Could be coincidence, but this was at the same moment that my solar panels were switched off because the system was expanded).

Since the router kept functioning OK I concluded that this must be due to my powerline system, so I bought a new box with 1 extender TLWPA4220 and 1 TL-PA4010. To my big surprise this did not lead to an improvement. I called my telecom provider to check the router, they checked but couldn't find a failure. I changed the cable connecting the router to the TL-PA4010, no change.  

Usually I reset the router to get WiFi back, but yesterday when the WiFi was down and I unplugged the ethernet cable from the TL-PA4010 to the router and reconnected it, and the WiFi was back, so I got the feeling that it must be due to the powerline system despite the fact that it is new.

Worth mentioning: the system worked flawlessly for almost 2 years. The house dates from July 2020 and has a 3 phase grid.

Hardware versions of the extenders are 4.0 and 5.0; the TL-PA4010 is 3.0

Hope you can help out!

  Hello @WimS 

There are some newer firmware for your Wifi powerline device, so it is recommended to update the firmware for them first. 

1. Ensure your WPA4220 V4/ V5 firmware is up-to-date: (select Hardware first  according to device hardware version, then download corresponding firmware )
Firmware for WPA4220 : https://www.tp-link.com/support/download/tl-wpa4220/ 

Firmware for PA4010 : https://www.tp-link.com/support/download/tl-pa4010-kit/#Firmware

 

2. Please use the TL-PA4010 in the new kit as the main powerline unit that connected to router in case something wrong with the old PA4010. 

 

At the same time, can you confirm

1. May I know House Led/LED Status on both devices when AV600 drops connection? 

When internet drops out, do all 4 powerline extenders lose connection or certain powerline extender lose internet? 

2. If House Led is On when issue happens, please check the IPv4 address and gateway and send us a photo: https://www.tp-link.com/support/faq/838/
When issue occurs, do not reboot or unplug powerline device,  try to ping the default gateway and send us the ping results:https://www.tp-link.com/support/faq/425/
3. May I know your network topology?e.g Archer C7 <Ethernet>PA4010 downstaits  ___<house powerline>WPA4220 upstairs.

Thank you.
