Just Off-->ON the router again (either L7-N-R2000 or DIR615 VerG2), as this two modem know as had problem, if u know how to configure the router, re-set wireless setting from default "Auto 20/40Mhz) to "20MHz" only, as this configure more stabil.

Buy a switch (5 ports one will do), an extra HyppTV box(must preset the account), place the switch on the router and link the port4(usual setup for DIR-615 or L7-N-R2000) to 5 ports switch, link either port of switch to Living-Room HyppTV box, pull another network line from switch to you room, and link to the HyppTv box on you room.
Wala! now you can watch HyypTV channels same time at living room and you room!
