Extending a wi-fi network across the street

I am trying to extend a wi-fi network across the street, less than 150ft. I control the networks and hardware on both sides.

The router is an AirPort Extreme (unsure of the exact model at the moment, one of the cigar box-shaped ones and not the more recent towers) broadcasting on 2.4 GHz only. When sitting in the room with the AirPort, I get around 25 Mbps down.

I’d prefer to leave the router in place due to it being hardwired to some office equipment.

I have the following equipment to accomplish this task:


  • ■ a TP-Link AC1900 802.11ac dual band "long range, high powered" wireless router
    ■ a TP-Link TL-ANT2414A 2.4 GHz 14dBi directional antenna
    ■ a TP-Link AC750 dual-band Wi-Fi range extender
    ■ a TP-Link TL-WN722N USB Wi-Fi adapter (compatible with aircrack-ng)
    ■ a few TRENDnet powerline network adaptors (wired only)

My first attempt at setting this up was to attach the 14dBi antenna to the center antenna jack of the AC1900 and aiming the flat face of the antenna’s enclosure toward the first house. The AC1900 is configured in WDS bridging mode for the parent network, and they are set to the same channel. But the speeds were < 10 Mbps and I experienced packet loss.

I moved the antenna to the USB adapter and used airodump-ng to monitor the network. From the second house I see -80 PWR and although I can get the RXQ high through aiming the antenna, speeds are not great; even standing directly outside the door of the first house (maybe 20 feet from the router) I get -50 PWR and maybe 15 Mbps. Although I can see the network from the second house, I cannot associate with it from so far away.

I’ve never set up a network covering such a distance, but I’m surprised that I’m having such a hard time. Is it unrealistic to expect close to full speed? Am I not using the correct equipment, or is there an easier solution? Would moving the antenna to the first house and broadcasting a stronger signal be better than trying to use it to pick up a weaker signal?

Personally, I would buy a pair of outdoor directional bridges, possibly in 5Ghz to avoid competition in residential area, and call it done. All this messing with antennas and junk just isn't worth it.
Router -> ethernet cable -> outdoor bridge <<<>>>> outdoor bridge -> ethernet cable -> switch or access point. Done.
Put the bridges up high enough on the houses to avoid blocking by traffic etc.
I like engenius, but Ubiquiti would be just as good.
