I'm currently wiring CAT 6 network cable throughout my house and am also installing several Ubiquiti NanoHD wifi access points on ceilings. The original house is a 1920s build and has lath and plaster ceilings; the 1990s extension uses plasterboard.
The fixing instructions offer two installation approaches:
- wall mount (though also recommended for plasterboard ceilings) - drilling four 6mm holes and using rawl plugs, plus an 18mm hole for the network cable:
- ceiling mount for drop ceilings - drilling four 3mm holes plus the 18mm hole and using a plate:
I intend to use the first approach for the plasterboard ceilings in the modern parts of the house, and my inclination is to use the second approach for the lath and plaster ceilings in the older part of the house since I do have access to the space above those ceilings.
However, drilling (in general) into lath and plaster gives me concern, particularly because of the horror stories I've seen of people trying to install recessed lights and the entire ceiling falling down and electricians saying "never again"!
My questions are:
- Am I over-thinking this? Should I just go ahead and use the first approach throughout the home?
- If I should use the second approach in the older parts of the house, do I need any thought as to where to drill the holes - e.g. should they be in the plaster gaps between the lath wherever possible, or should they be through the lath? I've seen conflicting guidance on this - arguing you don't want to disturb the lath, but that you don't want to disturb the bond and the "tails" of the plaster between the laths.
I could use Command Strips as a last resort as the devices only weigh 300g (10.6oz), but would still require the 18mm cable hole.
