Metal box

I plan to repurpose my current metal box for my V2 boards. My question is, if I cutout door and install lexan/plexi, will that be enough to help with wifi signal strength in regsrds to the metal enclosure. My router is basically across the hall behind wall from where Konnected will be in closet. Any advice will be greatly appreciated as i’m trying to get all leg work done before conversion kit arrival.
