QUESTION1:
The information provided on your web site has been very valuable.  I’m looking for some expert advice on how best to reliably and costs effectively extend my homes wireless network to an unattached building on my property. The metal building sits about 75’ away from my main residence, with about 15’ of elevation change (e.g. slightly up a hill). There are no LOS obstructions and since I live in a very rural area, other wireless traffic is mostly non-existent. I currently use 2 Linksys WRE54G extenders to provide access to the detached building, but the connection does not provide the reliability that I require.
For my home network I currently use a Linksys WRT600N router which manages connectivity very well for about a dozen wireless G and N devices. I currently run WPA-Personal with AES and TKIP encryption, with the N traffic on the dedicated 5 GHz band and G traffic on 2.4 GHz. I have a Linksys WET200 wireless bridge to provide connectivity for some of my home entertainment gear.
My wife has a Mac Book Pro with built in Wireless-N network adapter and our children have notebooks with Wireless-G adapters.  My preference would be to preserve the wireless capability within the classroom. Based upon what I’ve read on your site there are a number of solutions such as WAP with directional antennas or even wireless point to point bridge.  I’m looking to make a purchase and perform the installation immediately and would appreciate any recommendations for a cost effective and reliable solution.

ANSWER1:                

What you need is a cost effective point to point bridge to connect the two locations.  This will allow you to have a separate wireless router inside the remote building, which can be used for local access to the laptops in that building.  The part number is GNS-1150, http://www.gnswireless.com/GNS1150_Wireless_Bridge.htm, which includes everything you need to connect the two locations.  At the main location, you will connect the radio to the LAN port on your N router.  On the remote building you will connect the radio to the WAN port on your remote router, (not included.).  The radios should be mounted outside, and pointed at each other.  They are housed in a weather proof enclosure, with a small form factor of 6" x 4" square.  The wireless bridge comes pre-configured, so all you have to do is mount them and power up.

QUESTION2:
I have a customer that needs to connect their network to a building about 300ft away. I was looking at the wireless kit, Part # GNS-1125.  Is this the least expensive solution you offer for share a internet signal between two locations?

ANSWER2:

The most cost effective solution to bridge two buildings at 300ft, with clear line of sight, is the GNS-1150, http://www.gnswireless.com/GNS1150_Wireless_Bridge.htm.  This will include everything you need to connect the locations.  The radios are outdoor rated, and weatherproof, similar to the GNS-1125, however, if you only require a simply wireless connection to bridge your two remote locations, and do not require high throughput, the GNS-1150 will work great in your situation.  The connection will operate over the 2.4GHz frequency.

QUESTION3:
Hello, my dad has DSL at his home, I'm 500 ft. farther off the road and can't get the DSL  yet. Want to be able to pick up wireless from my house, the line of sight is pretty well clear what would be the best & cheapest way to do this?
Thank you

ANSWER3:      

If you are 500ft. away from your fathers Internet connection, you have two options.  The first would be to use a outdoor antenna mounted to the roof of your home, and point it toward your dads home to receive the signal.  Once it is connected, you would hardwire the cat5 cable directly to your computer.  This would be the cheapest way to get the signal, but quality of the signal depends on how strong he is broadcasting it.  Here is the part number to do so: http://www.gnswireless.com/GNS1655.htm.  A diagram will illustrate how the connection occurs.

Another option, and one that may be a bit more reliable, is to create a point to point wireless link between your two locations, which means having an antenna on each end, pointing toward each other.  The antenna on his home connects to the routers LAN port, and the antenna on your home connects to your PC's LAN port.  This will give you a quality signal between the two, and a solid connection.  The radios will be mounted outdoors, and only a single cat5 cable will be required to provide data and power, which simplifies the installation.
