will it still connect?

It depends what your walls are made of and how much loss there is in them. However, on the basis that the construction of your wall isn't changing, its down to the link budget. 10mW is 10dB less than 100mW. 6dB less signal will halve your range. With 12dB less, the range will be 1/4 of the original range.

So my guess is that with all else being equal, the maximum range with 10mW will be a little bit more than one quarter of the range with 100mW.
