The wifi signal in front room is 2 out of 4 bars; the signal in the back room is 3 out of 4 bars.
What I would suggest you do is temporarily move the Humax from the front room into the back room and do a test to see if thing work better. If they do work better then your problem is indeed the WiFi signal strength. You could either boost the WiFi signal strength or use Homeplug adapters to send the signal via the mains wiring (which is what I do).
