I have 3 powerline devices (AV1300). They have been working with stability for months. Recently for some reason they became dis-attached/dis-paired in terms of their network (the remote powerline adaptors were not connecting to the powerline adaptor connected to the router.

I re-paired the adaptor in the family room (used by the TV and HTPC) by following standard instructions of hitting the pairing buttons on each and they connected).

The other adaptor is in my son's room upstairs. We tried to re-pair it from there – no go. We moved that powerline adaptor to the same room as the router connected one. Still no go. When hitting pairing buttons on each, they keep blinking and never connect.

What else to do I try to get it paired again?
