this is the solution unless you have a warranty.

  @David-TP Nice to know that the capacitor has been removed. What does this do for people who bought one with the bad capacitor and the extender fails post-warranty? Are we SOL?

  @David-TP  I have 2 RE220s.  One is constantly rebooting with all LEDs flashing and not connecting.  The second one is still connected with all the lights lit, althought the wifi led is red. 

For the one that is constantly rebooting, I've tried moving to a different socket, all the reseting, firmware updating to no avail. Unfortunately, the warranty has just expired (2 years) so not sure what are my options.

  @DavCCC there is only solution if your warranty is expired: https://community.tp-link.com/en/home/forum/topic/653040?replyId=1523340

  @David-TP kann es sein das das Problem immer noch nicht gelöst wurde und die Produkte fehlerhaft produziert werden?

Darüber hinaus habe ich das Gefühl hier im forum nur umgeleitet zu werden und keiner hat plan mit dem Gerät irgendwas anzufangen
