Hi,

Could you please be a bit more specific about the issue?

In case you mean you have had the RE200 added as an EasyMesh node and now you want to delete it fom the EasyMesh network, then either log into the web GUI of the main EasyMesh router, go to "Advanced" -> EasyMesh" and click the wastebin icon next to the RE200 or in the Tether app log into the main router, tap on the icon resembling the RE200, tap on the three-dot menu and then select "Remove". (provided the EasyMesh router is made by TP-Link)
