What kind of range extender? One in particular that I am familiar with has only ONE external antenna, to send out the repeated signal. If that is the case, you'd be repeating nothing (because you'd be receiving nothing, I presume the first signal doesn't reach to the inside of the second home), and sending that nothing in the direction of the original signal.
Also, if you take a laptop, and stand in the front yard of the second home, can you receive the signal from the first home? Can't extend what isn't there.
I am trying to setup a wireless network on the second home by sending the wireless signal from the 1st house across the street. I have an omni-directional antenna at the 1st house and a directional antenna at the second home. At the second home the directional antenna is attached to a range extender. What am I doing wrong? Thanks!
