Not sure if this is the right place to ask, but does anyone know if I put a wifi extender in the shed (according to the drawing) will the signal reach the office? Thanks for any help.

Go stand with your phone where you’d expect to place the extender.

If it gets a strong signal, you are probably fine.

It’s good, not excellent, does it mean with the extender the signal in the office will be good or just weak?
You can put your phone in hotspot mode and place it where the extender should go, then see how good the signal in the office is.
That’s a good idea but unfortunately i have terrible cell reception and my mobile is useless without wifi.
So hotspot the wifi? 
I can do that? I never tried, I assumed it wouldn’t make sense to hotspot wifi.
You can at least on android and I thought ios too now but idk
