Excellent math work Lutz! Fortunately the poster is not dead :shock: as this link isn't in production on the channel you mentioned. We certainly do not condone or encourage operators to exceed FCC EIRP limitations. In situations where EIRP becomes a factor, MikroTik provides the ability to decrease ...
Thank you for the detailed scan! Indeed, there are a lot of radios there, and some of them pretty powerful. I'm assuming the antennas used are jirous, right? Which model? It would be interesting and useful to see how different antennas (especially mikrotik's and rocketdishes) work under same condit...
Could you post a complete frequency scan from the tower? I find it useful to find out how crowded is the radio space at your location, because some people around here find but most of them don't find an improvement upgrading to AC due to the interference. Is it a shared location with other ISP-s or...
We've recently upgraded our second N link to AC and couldn't be more happy with the results. The latest iteration of NV2 is keeping latency in check and throughput is excellent. We're now getting 100+ MB through a 20mhz channel consistently on both links. We've deployed dozens of N links and our exp...

There could be several reasons for this - but we need some more information before we start making suggestions. Can you post a screen grab of your Wireless and the Advanced tab when in advanced mode? There's most likely some interference near that customer Here are A few quick suggestions: Telnet in...
There are several ways to go about the setup you're looking for - for a brief overview.... You only need one Dual Polarity Antenna per side. The 7115HnD should work great. You'll run LMR 400 or a similar cabling from the antenna to the radio. Most of the antennas designed for this purpose come with ...
I could be mistaken but as long as the other clients and access point are using wireless cards with Atheros Chip AR5212 or newer you can run NV2 on your AP. All Mikrotik CPE's (SXTs, Sextant, Groove) support the NV2 Protocol. Without getting too complicated - protocols like NV2 and NStreme operate &...
What Radio Card and Antenna are you using on the access point? There are several Dual Polarity Sectors on the market that might meet your needs. Assuming that the clients currently connected to the AP have adequate signals you should be able to replace your Single polarity antenna with a dual polari...
Here are a few things I might suggest and a few questions as well - Suggestions First - I'd recommend upgrading your firmware to 5.14 - put the notes below into action - and then upgrade to 5.16 when you've got everything where you want it. If you're using a 433's the CPU power on them is such that ...
Interesting.....could it be disgruntled customers taking a bat to it? In addition to Brink Networks - we operate a WISP located in Edmond, Oklahoma. We have deployed 500+ Jirous enclosures over a 3 year period in an area known as Tornado Alley. Here's a recent local weather article mentioning expect...
We'd like to get some feedback on a new antenna/enclosure we recently started carrying. We're providing the enclosure free of charge to US customers...just pay shipping (for the curious...we're not marking up shipping...we're just looking for feedback). The dollar amount is credited to the total ord...
I had a chance to point a sweet Canon 135L 2.8 Macro lens at a couple of MikroTik products that we rely on everyday. The final images were prepped for desktop backgrounds... The complete collection of 16 images can be downloaded here: http://www.wispforum.net/entry.php?20-MikroTik-in-Macro!-R52Hn-an...
Welcome to the Forums EightBit! 8) Judging by Mikrotik's Request for input on this thread....your dreams may be close to becoming reality. :D http://forum.mikrotik.com/viewtopic.php?f=3&t=60008&hilit=SFP The RB2012 was at one point going to look something like this: http://www.ipmedia.cz/img...
It's possible that you might find something if you were to use IPerf and test all the different possible combinations - That being said...we have several APs configured this way in both the 2.4 and 5ghz and haven't noticed a drop in performance for the N clients. I think as along as you've got good ...
As far as a I know there isn't. Aside from Google Earth - The two tools we use most frequently are LigoWave's LinkCalc http://www.ligowave.com/linkcalc/ and TOPO USA buy it off ebay cheap...anything greater than 7.0 works AFAIK In TOPO USA - you create a direct route between 2 points, then in the Sh...
If the tower is registered with the FCC....This KMZ file, provided by Cavell, Mertz & Associates, Inc., will tell you the height of a particular tower.
A couple of thoughts - The higher you go...the more interference you're going to get. Use the Frequency Usage and Scan tools at both heights and notice what you see - I'd imagine many more SSID's show up at 500 M than 50 Meters. :lol: The Freq Usage and Scan tools can also help you find a "clea...
We had been noticing something was up too.... At some point I may write a post with screen shots and examples but until then I'll share this... Shortly after we started deploying 5.x we started noticing formally robust links were not quite as stable. We revisited our configurations and started makin...
We've deployed Jirous dishes throughout our network and although the specs say they only go from 5.4 to 5.9 - they operate quite well from 5.1 up to 6 Ghz. Regarding the wind resistance - our WISP operates in Tornado Alley - Aside from tornadoes - Straight line winds from storms in our area can exce...
HT Extension Channel was actually moved into the "Channel Width" Drop down menu. As long as you're using "20/40Mhz HT Above or Below" you're using an extension channel.
We had the same issue several years ago when we started making the switch. As long as your running 1.4.16 or greater (preferably 1.4.22) you will have a new option on the wireless configuration window called "802.11g-only" and "pure-g" under the "Operating Mode" section...
signal jumps between -20 and -40 which is much too strong. don't use tx-power 0, use for example 3 get them further apart, your signal is much too strong, this affects speed directly. like the article says, get the signal to be -60! the bridge setup is not a good idea in general, but that won't aff...
1.) I believe the RB800 is better suited for use as an AP with SXTs. Why: The CPU is a major factor when dealing with the higher throughput that N offers...even though it's clock is only 120Mhz faster than the 433AH, it's different architecture (PowerPC) and more RAM actually make it almost twice as...
Rishi: Hello and welcome to the Mikrotik forums! Here are a few things to try.... >You definitely need to upgrade to the latest version of ROS 5.2 >Make sure to upgrade the hardware firmware too! >Make sure you're using either NStreme or NV2 >Once you've got that done - start experimenting with diff...
Aside from your signal levels being too high to get the best performance....have you made sure that your settings match what I recommended at the blog link I posted?
Your signal strengths on chain 0 still make me believe you don't have both chains enabled.
There are several things that could cause poor CCQ If you can - you need to improve your signal strengths. Try re-aligning the antenna's. If that doesn't help - You may need to switch to external antennas to get more gain. If you haven't already - work through all of the different channels. And you'...
Using 5mhz channels with NV2 saved my bacon on one particular tower I've always had trouble with. There are over 100 2.4 clients connected to 4 different sectors....managing interference has always been an issue...until NV2 came out. We've been using it since beta...and it's never had a problem. The...
It looks like you only have one chain enabled. I wrote a tutorial for connecting two SXT's together...you might skip to the configuration section for details on how to get the best out of your connection. http://www.wispforum.net/entry.php?5-How-to-Connect-two-Mikrotik-SXT-5D-s-In-Bridge-Mode-Part-I...
I put together a tutorial for connecting two SXT's together in bridge mode. Here are some Screens shots of the final bandwidth tests...

Two SXT's in bridge mode should do the trick! You can align the antenna's using the LED guide on the back shown here: http://routerboard.com/img/pricelist//204_l.png There aren't any "tricks"....just make sure you configure both sides to have the same settings. Get them connected in your o...
Artie: Hello and welcome to the Mikrotik Forums! Sorry for the delay in response....we're all very busy :D From the looks of your design it appears that you want the fastest most realiable link possible. With that in mind here are a few things to think about. You only need one card per RB800. The R5...
You could use both Mikrotik and Ubiquiti products - Mikrotik for the clients and AP and Ubiquiti for the AP Antenna. I'm assuming that the 3 clients are spread out and not directly in a line. If you wanted Dual Pol All the way you would need: 3 RB SXT's for the clients 1 RB 411AH & RB52hN for Ra...
This calculator provided by Times Microwave should help you when deciding what cable to use. http://www.timesmicrowave.com/cgi-bin/calculate.pl As Mramos pointed out, the amount of signal loss (attenuation) depends on the frequency being used. Using the calculator with a frequency of 5745mhz you wou...
didit7039: Welcome to the Mikrotik Forums! It would be very difficult to provide advice without more information... The short story is...it would be wise to use more than one of any type of AP (Mikrotik or otherwise) with a well planed antenna layout and Bandwidth management system to ensure that ev...

WirelessRudy: I should have been more thorough in my testing. I tried to go back and recreate what I was experiencing with ANI disabled and enabled when using the NV2 package and I couldn't recreate it. I tried to recreate the OP's scenario as well (upgrade from 4.16 to 4.17) on a tower that has a 2...
I experienced a similar situation after upgrading to 5.0 RC11 and the fix was to disable Adaptive Noise Immunity. When enabled none of the clients would connect when using NV2. After turning off Adapative Noise Immunity they immediately connected. ****Update**** After Upgrading a radio from 4.16 to ...
Here are a few things to try. Reset the configuration of the cards on both sides. Then reconfigure them. If this is a remote link and you don't want to visit it to accomplish this....then you'll need to write a script that resets the card the applies the settings you want then re-enables the card. I...
I've been helping deploy the Mikrotik / Ubiquiti Combo in both 5 Ghz and 2.4 Ghz. I'll show the one of the 5 Ghz setups first. The sector is being used to feed both clients (currently 6) and to backhaul service to PicoPops (currently 2). On the Tower: RB800 Running RC10 with Firmware 2.30 Ubiquiti 5...
Hello Airin! These are the first things that come to mind on a link like this. When diagnosing connection problems...it's usually helpful to start close in then work your way out. So use the BTest tool on a PC to do a test through the client radio just to the AP. Once you have that setup...you can s...
I've seen most ethernet problems be resolved by doing a few things. Use a cable that is sheilded and has a "Drain Wire". Wind blowing across the cabling on the tower will cause static electricity buildup and without drain wire it can damage the ethernet port. Note that the drain wire shoul...
