My detached garage has a streaming TV and that TV is approximately 65 feet from my router. Not enough signal. I bought an extender with two antennas from Best buy for $50. I was skeptical. I plugged it in at the outlet nearest the garage yet furthest from my house router- so my extender is approximately 38 ish feet from the garage TV. My signal is now plenty strong enough for the streaming TV and me playing on my laptop.
