Faraday cages cannot block stable or slowly varying magnetic fields, such as the Earth’s magnetic field (a compass will still work inside one). To a large degree, however, they shield the interior from external electromagnetic radiation if the conductor is thick enough and any holes are significantly smaller than the wavelength of the radiation
I’m certainly no expert, but something tells me the cage in OP’s pic doesn’t fit the criteria to act as a faraday cage.
E: Nope, I’m wrong. u/deegeese has informed me on how big the wavelength is.
Probably not for a MIMO AP. The whole idea is that you solve the equations to optimize in the presence of multipath. It’s legit wizard shit but it’s the reason why your cell phone works in a parking garage, because the optimal channel is bouncing off the ventilation shaft. For any reasonably modern AP, it should work the same way. This might hurt a bit but not that much.
It will not act as a Faraday cage, the holes need to smaller for that, about 1 cm max. However, wifi signals do get disturbed by a cage like this due to the low power of these signals.

The mesh is not dense enough to be a true Faraday cage for 2.4GHz, but is dense enough to hurt signal strength.

MIMO will solve lensing issues but not internal reflection or absorbance.
So like OP says, it’s a signal strength issue.
It says WiFi is “slow” not “off.”
I have definitely personally experienced WiFi instability with metals in between the WiFi and a PC.
Looks like possibly enough to make it drop a bunch of packets to me at least.
