Edit, March 2017. Still working fine, I now have added an ethernet switch at the well pump and am also monitoring the on/off state of the well pump from my home since some days it seems the pump relay been sticking 'on' and consuming 32kWhr rather that the normal 1 kWhr. I wish I had bought the 1 to 4 expander version of this unit now, just tried to buy one but amazon says they are unavailable.
So what todo? Buy a StarTech 10/100 VDSL Etender.
This device is perfect to go up to 1.5 km (4921 feet). It converts the LAN Ethernet signal to VDSL2, which appears to be a high frequency sound. To quote wikipedia "Second-generation systems (VDSL2; ITU-T G.993.2 approved in February 2006) use frequencies of up to 30 MHz to provide data rates exceeding 100 Mbit/s simultaneously in both the upstream and downstream directions. The maximum available bit rate is achieved at a range of about 300 meters; performance degrades as the loop attenuation increases."
Unfortunately, the first pair of these things I bought did not work. The VDSL2 signal just would not synch. I was using Ethernet cable I had laid before I knew about the 100 meter limit. The manufacturing company has great tech support and I learned more about Ethernet and VDSL2 than I probably ever imagine I would need to know.
Several things are important to know. First, you can use a single pair, twisted or un twisted, however a single pair wire is really hard to find for outdoor use. Wiring up an 8 twisted pair wire with an rj45 connector works great for the VDSL2 connection. I bought mine from Amazon.
Second, test two units using an ethernet patch cable, these come with most routers. This lets you test the whole system in the privacy of your own home and obviates trips between your remote location.
Third, (once the VDSL2 is shown to work) wire the ethernet connector from one of the outlets on the back of your router with an internet connector to the Ethernet port on one of the StarTech devices. All the dip switches up (this sets this one to CO central office). At the other end, set the dip switch on 1 down, all others up (this sets it to CPE customer premises equipment (how twentieth century these terms)). Wire the Ethernet patch cable to the internet side of your remote wireless router. I did not change the default settings on either wireless routers and it works flawlessly.
I now have 6 mbits/second at both locations.
Changed internet provider to Sky Tech. Now get 9.9 mbits/sec
On 2016 May 3 we had tremendous lightning and hail. My office internet went down. Remember, I was paying ~700/mos for Exede internet at both locations. Started trouble shooting. Wire appeared intact. I had bought 2 of these dices. Swapped out each. Wallah internet back up. Bought spare ser again. Really a great solution if you need internet over a few kilometers
I put a set of these devices on each end of the Ethernet run and WALLA - I had a link that was now getting 70 Mbps downstream. A simply no brainer solution. I wouldn't think twice about ordering this again, should I have a long Ethernet run.
I would buy these again in a heartbeat.
My only comment. I wish they made units that can support 1GB service (I could not find any device by any manufacturer - that can provide 1 GB service - even at 500 feet).
I would buy these again in a heartbeat.
The connection itself is completely transparent to the network. There is no configuration required other than making sure the four DIP switches are set correctly (they came out of the box correct for me) and then just plug and play. When I plugged in the second box at the remove location, it took about 5 to 10 seconds to establish the connection but once up it was solid and fast with no noticeable latency. My particular application looks something like this:
Internet -> Modem -> Router -> StarTech Extender -> 500ft of Cat 5e in Conduit -> StarTech Extender -> POE Switch -> IP Camera
The extender is EASILY handling all four camera feeds at about 4mbps per each (16mbps total) with no problems. When I use an app to view the cameras on my phone, they pop right up in seconds. I am confident that the extenders are in no way a bottleneck in terms of speed and latency for this application.
This is the perfect device for connecting a home network to a remote location like a barn, detached garage, or IP cameras at a remote location on your property in circumstances where the distance is greater than 300ft.
No comment on how long they last as I'm only a week in but the connection has been 100% reliable in that period of time.
EDIT: It's now been a year and a half of continuous operation with 100% up time.
