So you just really need to experiment with the positioning, because the modem send and receive signal is a little on the weak side for these kind of buildings...and I had problems connecting my notebook to the internet on the wireless upstairs in the rooms because the modem is close to the TV in the lounge, I had to move it around a few meters to find the correct position, to get the signal upstairs.
Wireless does work off direct waves, line of sight, and you can occasional pick up the signal, by bouncing it, but it will not go through concrete this is when the signal will just bounce off and around a room. Try to think of the signal like a ripple in calm water, when you drop a stone in still water, the waves extends, until they hit a solid and bounce back or it continues until it fades.
QRM method is worth trying or you can buy a signal booster for the hall way, it acts like a remote rebroadcast of the signal and is probably more powerful on the sender side than your sono.
All line of sight signals are the same and do not go through solid material unless it is conducting the the signal on that frequency range, so positioning is very important
