[Skunkworks] UMTS / HSPA Question.

Hello guys, I live in a place where signal quality is soo bad I only get spotty reception switching between EDGE, UMTS and HSPA. I have an Airtel Modem connected to a TP-Link router that gives me net. In order to know where to mount the router, I need to establish which spots in the house have HSPA, but I cant figure how to check what the modem is receiving. Could anyone help? Is there a way to check while Modem is connected to router? Regards, & Thanks in advance. -- *“The twentieth century has been characterized by three developments of great political importance: the growth of democracy, the growth of corporate power, and the growth of corporate propaganda as a means of protecting corporate power against democracy”*
