Xen Xt8 wifi - solid blue light on node

[markzkennedy747]

Hi - I have had a Xen XT8 wifi network for a few years and it was worked well. One of my nodes now has a solid blue light and is not working and I cannot seem to reconnect it to the network. Any ideas welcomed.

Someone had a similar issue.  Did you hard reset the node, remove it from AiMesh on the primary router, then try to add it back?
