Hi,

We have 4 deco x20s and a givenergy Wi-Fi dongle for our givenergy solar system.

Recently the givenergy dongle dropped from the network..  spoke with givenergy saying they didn't support mesh networks.  Also only support 2.4ghz networks.  Even though it has been working for 2 years.

Firstly I don't think I can disconnect the dongle and try on another device.

So did some trouble shooting.

1) connected to the Wi-Fi dongle directly as it has its own hotspot.  My network credentials correct and could see 1-2 of the x20s devices.  Turned off all but main, still didn't connect..  disabled 5ghz, no joy

Tried running the network optimizer, channels changed but no good..  tried several times..  no good

2). Had a mifi router from three.  Reconfigured givenergy dongle to use that network..  could see it and connect to it..

Any thoughts??
