    I am attempting to extend the range of a WIFI network to cover two buildings, about 300 ft apart. I have installed a D-link extreem -N router and 3 7dbi antennas, however I am still a bit short in range. ( each building has a firewall which seems to be limiting reception).

    My research suggests that range expanders are unreliable and difficult to set up.

    Thanks

    Perhaps some directional antennas might be the ticket?


    Hawking Tech has a number of products that will help you increase your wireless range. The root page is Hawking Hi-Gain™ WiFi Range Extending Products.


    Another way to increase your signal strength is by the use of hi-gain antennas. You can choose from omni-directional or directional models, here are a some examples.

    Hawking [HAI7SIP] Hi-Gain 7dBi Omni-Directional Antenna

    Hawking [HAI15SC] Hi-Gain 15dBi Corner Antenna

    [HAO14SD] Outdoor Hi-Gain 14dBi Directional Antenna Kit

    For 802.11n applications, this ZyXEL ANT1106 6db omni-directional antenna can be used.

    For really long range outdoor applications, this 24dB parabolic WiFi Antenna may be a good choice.

    If you have a wireless adapter that doesn't have provisions for an external antenna, one adapter that I've had good luck with is a Rosewill RNX-G1 USB Wireless Adapter. It's feature is that is has a removable antenna and will accommodate replacement antennas.

    This is just a sample of available products, many people have hi-gain antennas with similar specifications, but I haven't seen any other suppliers of signal boosters.
