Mesh is too big

Folks,

WiFi occupies the 2.4 GHz band, same as microwaves. A Faraday cage effective for blocking RF at that frequency needs millimeter-size or smaller mesh holes. It might stop AM (kHz) and even VHF/UHF ( 1GHz), but not microwaves.

So this notion of chicken wire being an effective shield for WiFi just doesn't ring true.

That mesh behind the plaster isn't exactly chicken wire sized. It is a pretty small mesh pattern. About at least 1/8"x1/4" diamond pattern.

This still isn't small enough to block 2.4GHz, but it sure may disturb/distort it.

I think that it absolutely can contribute to blocking/distorting wifi signal! WiFi is hardly robust, being very low powered, it does not take a lot to block/diffuse transmission.

None of the stuff I saw on the job was that small. It was the stereotypical "chicken wire" size.

some of the hundred year old places I have lived in, had some mesh that small.
Plus that mesh like that can be used in some semi-modern buildings to form the plaster door frame/openings. Where it's just a pass through opening no real door.

Then I guess combine that with the lead paint as someone else mentioned.
