Author Topic: Wireless Networking Question Bobby Henderson "Ask me about Trajan." Posts: 10973 From: Lawton, OK, USA Registered: Apr 2001 posted 03-28-2011 06:44 PM                     Although the EnGenius radios are powerful and designed for outdoor use, they're not very expensive (around $75 to $80 depending on where you buy them).  |  IP: Logged Bajsic Bojan Expert Film Handler Posts: 190 From: Ljubljana, Si, Eu Registered: Aug 2008 posted 03-29-2011 02:33 PM                     we are also in the process of getting something to connect the network of two or three buildings. We were looking at getting antenna based wireless but we have no line of sight between buildings. So, is there an omni-directional, wireless solution, with only 2 units, at least 30Mbit/s, 200yards apart, with buildings in between, possible? In sub-2k$ range. The alternative we have is running optical fibre direct from one location to another, its a monthly expense tho. I've looked at basically lots of things but i'm not that wifi-savvy to know if perhaps this Tranzeo WiMax thing would do the job, or i'm way off. any input appreciated  |  IP: Logged Bruce Hansen Jedi Master Film Handler Posts: 847 From: Stone Mountain, GA, USA Registered: Dec 1999 posted 03-29-2011 05:27 PM                     I have seen units that will send a network over power lines. I don't remember who made them, or where I saw them. But, they may not work well in a industrial area.  |  IP: Logged Frank Angel Film God Posts: 5305 From: Brooklyn NY USA Registered: Dec 1999 posted 03-29-2011 09:04 PM                        Barry, if you only have AC running to the ticket booth, you can use an Audio-Over-AC device specifically geared to either voice bandwidth audio or modem data. GE and PhoneX makes them. On Amazon They are consumer products, yes, but we have used them very successfully for modem connections to telephone lines with the only available connection was AC. Card Readers will work equally as well. Only thing, obviously the transmitter and receiver have to be on the same leg of the mains transformer. You also wouldn't want to use it in a REALLY noisey AC/high EMI environment. For under $75 though, it's not much of a risk to try one out. As I said, we have used them very successfully.  |  IP: Logged Barry Floyd Phenomenal Film Handler Posts: 1079 From: Lebanon, Tennessee, USA Registered: Mar 2000 posted 05-10-2011 04:46 PM                        We finally got everything installed and working on our new wireless connection to the boxoffice. I used Bobby's suggestion and went with the Engenius EOC2611P radios, and it works like a charm. I bought external antennas, but I really don't need them. Set the one at the concession stand in "Access Point" mode, and the one down at the boxoffice to "Client Bridge", and it essentially acts like a 400 foot long network cable. Thanks everyone for your help and suggestions.  |  IP: Logged Bobby Henderson "Ask me about Trajan."

We tend to set them in bridge mode for peer to peer use only and with MAC address filtering enabled. Basically the radios only see themselves and the "access point" side of things isn't available to anyone wardriving around in the area with a notebook computer. Basically it eliminates the chance of anyone using the transmission from those radios as a means of invading your network.  |  IP: Logged Barry Floyd Phenomenal Film Handler Posts: 1079 From: Lebanon, Tennessee, USA Registered: Mar 2000 posted 05-11-2011 10:44 AM                        I did enable the security encryption with a 20 character hex-digit key, and suppressed the SSID so it doesn't broadcast the availability of the access point.  |  IP: Logged Barry Floyd Phenomenal Film Handler Posts: 1079 From: Lebanon, Tennessee, USA Registered: Mar 2000 posted 05-12-2011 02:09 PM                        Somebody explain this..... Get everything hooked up with the new wireless bridge, and everything works splendidly. I can process credit cards via the net both from the hard-wired terminal and the terminal on the new wireless bridge. We also have a network DVR plugged into the Netgear switch that we can remotely monitor the cameras when we're not at the theatre. I can sit here at my desk at the office 15 miles away from the theatre and watch what's going on down there all day long. What I can't do is connect to the internet any longer on the theatre network with my laptop. Keeps telling me "Connected with limited access". I tried the wireless connection - nothing. I tried hard-wired with an ethernet cable to the laptop - nothing. Go home with the laptop, set it on the kitchen table and it automatically connects to our home network and I can surf the web with no problems. If I can surf the web at home - I don't really think I have a computer issue. Since the DSL modem/router is handing the credit card data and DVR signals over the web, I wouldn't think I have a DSL modem/router problem. The only thing we did different yesterday at the theatre was to install external antennas on the Engenius bridge radios, and flip the switch on the back of the radios from internal to external. Would the external antennas really cause such an issue?  |  IP: Logged Chris Slycord Film God Posts: 2986 From: 청주시, 경북도, South Korea Registered: Mar 2007 posted 05-12-2011 03:16 PM                     Try changing it back and see if all works well. Then you will know for pretty much for certain that something is wrong with that external antenna or the connection to it. Although I think you need to instead go to http://support.microsoft.com/kb/930517/ The above link tends to indicate that early versions of Vista that haven't had the newer Service Pack installed will give that error message when you connect through a networking bridge. So if you haven't updated in a while, now would be a good time.  |  IP: Logged Bruce Hansen Jedi Master Film Handler Posts: 847 From: Stone Mountain, GA, USA Registered: Dec 1999 posted 05-13-2011 07:46 PM                     Try rebooting (unplug power for a minute) the wireless router that your laptop is hooking up to. They get confused at times.  |  IP: Logged
