General suggestion is to try to make the connection wired. The best wireless connection is not as good as even the worst wired connection. Lower latency, faster speeds, all around better for gaming. You would either need to move the modem/router or run a ethernet line from one room to the other.

If that's not possible, there are networking options that use your electrical socket, or cable wire (which you may already have in both rooms) to form some kind of connection. If your interested I can give details.

Other then that I would need to know more about why it looses the wireless. Next time it happens do a Xbox Live connection test and see what the results are. Also, what kind of modem and/or router do you have?

i would be interested in the wired networking options you mention.

The three main way to get a wired connection, in order of effectiveness is Ethernet (CAT6), MoCA (Coaxial/cable), and Powerline. Included are 3 links above that give a overview of a basic installation. Ethernet one is bit complex because its the professional way to do it, full outlets and everything, but sometimes its as easy as buying a long ethernet cord and duct taping it to the ceiling or drilling a hole in the floor. If you can't do ethernet, I would suggest MoCA because powerline can sometimes be laggy and problematic depending on how your house is wired for electricity. The same goes for MoCA but if you have good signal going to your modem, chances are you already have halfway decent cable wiring, but there are certain signal requirements. YMMV. Feel free to ask any questions.
