Increase area of NetGear 1100 coverage

NetGear Night Hawk 1100-- I am using this to get signals from an ATT tower. I have four bars and working well next to the Night Hawk. I have a large home and not able to connect to my computer 40 feet and three walls away. Can I hook up an extender such as a whole system mesh extender to the Night Hawk to cover my whole home?

Thanks,

Big Wally
