Hi, I'm the only administrator at my fathers Deco M5 network. This usually works great as I can help him with any home network issues from a distance. However, now he needs to expand his network with one more Deco unit. Is there somehow possible for me to help him with this from a distance (he plugs it in and I add it)? 
 

If not, this would be a nice feature.

I'd rather not give him administrator rights as he is really bad with everything technical...
