Problem with NS5

[silviolmj]

I bought two NS5 to do a p2p link, but i'm having a problem, one ns5, turn on, pass 5 minutes turn on, it's reboot.
Can someone help me with this problem?

[guidonet]

Try it with factory default setting.
Try another power supply or cable set.
Use different power AC plug. Discard all electrical stuff first. It´s the easy way... and more common for your problem

[silviolmj]

I've tried other network cabe and default configuration, and none of this things chance, the nanostation continuos rebooting.

[guidonet]

Sounds like a temperature problem ( overheat ) ... or something going wrong in that unit.

[silviolmj]

I thing insn't temperature, because it happened on night too, and night, the temperature is 23º +/-.

[fibrewire]

check for watchdog settings, its something like "on no ping for 5 minutes - reboot"

[dan]

how long is the catv run? check the power output with a multimeter at the dc plug. then again at the end of the catv if possible.

I said:

This discard
Check for watchdog settings, its something like "on no ping for 5 minutes - reboot" because in default factory you got no watchdog

Try another power supply or cable set. Use different power AC plug. Discard all electrical stuff first.
This discard
How long is the catv run? check the power output with a multimeter at the dc plug. then again at the end of the catv if possible. because if you change cable set and power supply(even removing from the actual location and testing on the table with short cables ) you eliminate this problem.

I thing insn't temperature, because it happened on night too, and night, the temperature is 23º +/-
overheat means internal component trouble...

Follow this tips first, specially removing all and start again on your desk.

[silviolmj]

I tried all the things, but none of them resoved my problem.
I try to put the NS5 connected on my computer and it show the problem resolved, because after, I connected the network cabe on a swith with 1 AP cisco 2,4 and 1 ovislink 2,4 too.
Its nomal when you plug the NS5 on a swith, it reboot sometime?

*Another problem, a connect(wireless, not lan) both NS5 with signal -85, will it work? Because I can't access the other NS5. (One I set Station WDS and other, I set AP WDS)

[guidonet]

Lets see if I understood well… if the NS5 is connect to the PC do not reinitiated, but you connect it to switch if it is reinitiated?
Silvio.. where are you from... tal vez me entiendas mejor si te explio en español?

[silviolmj]

No problem to talk in english.
Yes, thats it, you are right.
Other problem I said, with -85 signal, it will work well?

[guidonet]

Yes, it will work if the signal will not variate. You are at the edge of no connection ( -92 ). If you fix data rate at 6Mb it will more stable.
About reboot problem... it still?

[kijoma]

hi,

the power is coming from the switch? or from a seperate power supply?

got the thought you may be powering the unit at the wrong voltage.

[silviolmj]

Yes, the rebooting problem stoped, I don't know why, because I changed anything, if it starts again, I tell you.
The other thing, I've tried everything, the signal stay -83 to -85, I put:
Rate Algorithm: EWMA
Noise Immunity:For Channel Hopping Signals
ACK: automatic
Speed: automatic too
distance: 3.5 KM +/- 2.7 miles
I'm gatting 880 kb's in download, can I get more than it?

[kijoma]

hi,

looks like you can only try moving the radio around to get a better signal. then you will get more speed.

[silviolmj]

I've already tried that, and nothing change. :cry:
I tried to, change the "Channel Spectrum Width", putting it in 40Mhz but it didn't conect more, it only work in 20Mhz. There is some reason to it happen?
And other thing, I change the "Channel Shifting" too, put some channel, it didn't conect too.
Why?
:?

[guidonet]

Bring me more details.
Like signal in both ends.
Clear LOS.
Are you doing the change in both ends?

[silviolmj]

Yes, i'm doing in both NS5, I will show some exemples:

I set ate the NS5 AP 40Mhz(Channel Spectrum Width) and at the other NS5 too, but they didn't connect, so I returnt in both NS5 to 20Mhz and then, they connect.
Another exemple, I set enable the Channel Shifting in both NS5 and set the channel 53 for exemple and they didn't connect too, so I return to disable and set the 52 channel, then both NS5 connect
Why it happen?

[guidonet]

Both in same country set?
NS5 1 as AP
NS5 2 as Station
OK?

[silviolmj]

Yes, I set in both, USA country.
NS5 1 Access Point WDS
NS5 2 Station WDS

I'm only doing a P2P, what's betther to use, WDS or not?

[guidonet]

Try without WDS... some time they are weird using WPA and WDS too.

[silviolmj]

Do you think if I put station and Access Point only, I will get more speed?

[guidonet]

Nothing to loose. You will reduce broadcast... and keep the eye in signal too.

[silviolmj]

Why it will reduce broadcast?

[guidonet]

Hi Silvio, it will reduce broadcast because it don´t negotiate a WDS link.
Take a look of this test. It was performed with similar conditions as yours.

[silviolmj]

Yes, this screen shot it like my NS5 status, so, I will change here and tell later what happen

[silviolmj]

I've tried to put AP and Station, but is the same setting WDS, look my AP config.:

[kijoma]

hi,

you are using 5260 mhz on an ns5?

the aerial panel isnt designed to work down there, try changing to say 5500mhz if its legal there, if not 5745mhz etc..

[guidonet]

Well done Silvio..... 6Mb is a nice throughput with -85dB. Try a higher channel... and may be fix antenna to vert or horiz pol

[silviolmj]

I tried all the channel, 52 is the worse, 149-164, they didn't connect.
I will try to set Hor or Vert pol.
Today, I tried to put the NS5 on a satellite antenna(SKY or Direct TV), but it didn't work, there is some reason?

[WHT]

Go here for info on setting it up with a satellite internet connection.

http://forum.ubnt.com/forum/viewtopic.php?t=6337&highlight=wildblue

[silviolmj]

I'm not talking about satellite internet, its just use the satellite antenna, witch is used to satellite television, see the photo:
http://img510.imageshack.us/img510/5823/image231rz2.jpg

Why it didin't work?

[WHT]

Well discussed in:

[silviolmj]

Ok, I read the posts, but I don't understand, can you help me?
do you thing will it work?
how?

[MoWiNet]

If you get the nano positioned correctly it will work. You should see over a 10dbi receive gain increase. Transmitting is not optimized but will also increase nearly the same amount.

[silviolmj]

Interesting, so it will work and I will get a better signal?
I will put the antenna like zirok's antennas?
Exemple: http://www.awtec.com.br/site/images/produtos/zirok58.gif

70º is straight or nano is diferent?

[WHT]

There is one and only one point that the dish will focus a signal. The NS has four internal patch antennas, therefore one and only one will be at the focal point.

It appears that you have the NS5 such that the focal point is in the middle of the four patches. Moving it up or down about an inch will bring the 2nd or 3rd patch into the focal plane.

The gain of a single patch is about 3.5 dB and the gain of an offset dish is about 30 dB, you'll get a total gain of 33.5.

[silviolmj]

So, it will be very dificult so found the socus, and see the image and aw answer my question there.
http://img516.imageshack.us/img516/5610/parabolicmisfeedoe4.png

[WHT]

No....the NS has to be at the same angle as the short almost vertical mounting arm. But you have to slide the NS up or down for best signal.

Also it has to be mounted closer to the dish at the same distance from the face of the dish of the original satellite feed horn.

While the dish can have up to 30 dB gain, you'll loose about 10 dB because of shadowing caused by the NS. For this reason a satellite dish uses that offset feed to prevent a shadow compared to the center focal point feed of a WiFi dish or grid antenna.

From experience, you only have a about a one millimeter tolerance on the exact and correct position. If your off more than a millimeter, you could loose another 10 dB of gain.

You'd be far far better off using a flat sheet of metal with a paraboloid curve to it.

[muhti]

We can use aluminium foil apply at reflector surface with paper glue, and find focus disc antenna with point the antenna to the sun, bright area is the focus. NS antenna must be apply at that area.

-muhti.

[silviolmj]

That will be very dificult, but seeing the photo, do you think the angle with NS and antenna is kind correct?

[WHT]

I'd have to check a satellite dish to make sure.

[kijoma]

hi,

looks like an ideal job for a loco 5

[guidonet]

Hi Silvio, I´m back. A storm still me busy.
What are you trying to do? Some kind of experiment? or you really need to get that link?
I can send you the back up files to load in your Nanos. Send me a PM with your preferences and I´ll write it for you.

[silviolmj]

Hi

i'm tring to get link, because my signal is -85, and i want more than it, so, how can i get better signal with this satellite tv antena, using NS in there?

[guidonet]

Hi Silvio.... you got another problem with this link.... because for a p2p in 3.5km the signal must be near 60dB, not lower. email me your Google earth coordinates and attach both back up files from your Ns5.

[spainuser]

Hey ,silviolmj and guidonet what firmware do we use ?

Thank !

[guidonet]

v3.2.3-rc

[silviolmj]

He is using the same then I. (11.24.08 Ubiquiti Air OS v3.2.3-rc - NanoStation5 )

[silviolmj]

My coordinates is:
AP: 2057'55.75''S 4828'32.96''O
Client: 2056'22.03''S 4829'33.86''O

Today, I tried everything to use the NS5 with parabolic, so, after 4 hours, I got a signal, -76 to -80, better, but not well.
What to do?

[WHT]

I looked back to see how far your path is, but didn't find anything. How far is your distance?

[silviolmj]

My distance is 3.4 KM

[guidonet]

Hi Silvio, are you sure about clear LOS. I can see a little forest in the way.
Try a higher place or move towards a flank to start. Few meters make big differences in this case. How tall is the client location?

[WHT]

Only 3.4 k Km??? You should be able to make the link with stock NSs' internal antenna. You have some other issues causing your problem.

[silviolmj]

I agree with you "WHT", but I don't know what to do.

Yes, the coordenates witch I show you its correct.
I take a screen shot in google earth from my city, the distance and where is the AP and Client, the name of my city is Bebedouro, if you want to search, you put in google earth Bebedouro SP.

Photo:

http://img262.imageshack.us/img262/5687/googleearthda4.jpg

[silviolmj]

The client is 2004 feet from the sea.
My city is 1967 feet from the sea.

[WHT]

What are the exact heights of both antenna to within half a meter. Is the AP radio AT LEAST 11.5 meters? Not 11 meters, but at least 11.5.

[silviolmj]

Client is 13 meters and AP is 15 meters.

[WHT]

From the GPS lat & long, it looks like you may a Fresnel issue at the AP side (the soth radio).

With both at 10 meters, you have only .2 clearance.

With the AP at 10 meters, you would have to raise the client to at least 21 meters.

With the client at 10 meters, you would have to raise the AP to at least 11.5 meters.

This is not including any buildings in the way.
If you have a mere 2 meter tall dog house 240 meters to the north, it will block your signal.
If you have a 4 meter single story buildilg 300 meters to the north, it will block your signal.

[WHT]

Info corrected in a later post.

[silviolmj]

So, seeing this image you conclude that i need to do what?

And, how can i get this program? (radio Link)

[silviolmj]

Guidonet...there is something wrong here...look

My coordinates is:
AP: 20º57'55.75''S 48º28'32.96''O
Client: 20º56'22.03''S 48º29'33.86''O

[WHT]

I kinda figured:
AP: 2057'55.75''S 4828'32.96''O
Client: 2056'22.03''S 4829'33.86''O

Was really 20º 57' 55.8

But yeah...looks like you have an AP Fresnel problem.

[silviolmj]

Hm, I understant, so, how can i resolve the problem having the fresnel?
Please, tell me where can i get the program witch you used to show the image, radio link?

[UBNT-Mike.Ford]

Hello Siliv,

To resolve this you will need to raise the antenna height to clear the interference zone.

Thanks,

Mike

[silviolmj]

Ahh ok, and can you tell me where can i get this program or can you send me it? please :D

[UBNT-Mike.Ford]

Hello Silvi,

WHT should be able to point you in the right direction.

Thanks,

Mike

[silviolmj]

I found the program and installed it, but i need the image from Brasil to put there, can you tell me where can I find it?

[WHT]

Those are the elevation data files RM uses to create teh topographical maps.

There's a text file, don't recall the name, that shows you how to unlock the Mapquest, Google, Yahoo, maps..etc...some will work for SA. I think you have to delete some ** or // in front of the link name...the text file explains it all.

[silviolmj]

Ok, thanks.
Other thing i wanna know is, why my signal chance a lot, it -80 then it goes to -75, -72-, -77.
How to stop it?
Is because the fresnel?

[WHT]

Your boresight signal remains the same, but the Fresnel diffracted add and subtracts to it.

[silviolmj]

So, nothing to do to estabilise it?

[WHT]

Without a minimum of .5 clearance, there isn't much you can do.

[silviolmj]

Ahh, ok, thats may the reason witch i can't set the channel 149-164?
Only 44,48,52,54,62,64!
Can you explain how to use the progm? (Radio Mobile)

[WHT]

Can't set the channels? Do you mean you can't select those channels in the web GUI or you can indeed select those channels, but they don't get a good signal?

The RM web site has some (outdated) links for RM...one of these days (and I've been saying that for five years now), I'll build my own tutorial.

[silviolmj]

Sorry, let me explain better.
I can set it in both NS5, on brower, but if i set this channels, the NS5 doesn't connect, signal -0 or same times, -93.

[WHT]

Ok...let me think.

Ch. 40 to 48 is limited to 17 dBm and Ch. 52 - 164 is 22 dBm if you use obey regulations in Brazil. That means you're trying to connect with same power level at 52-64 and 149-164.

I need more information. With you at your end wired into your NS and your friend at sis end wired into his NS, call him on the phone and coordinate the channel changes. Set your end to 52 and see if he can see your NS in the web GUI: Link Setup tab > ESSID: > Select. Then try again with you setting your NS to 149 to 164.

[guidonet]

Hi Silvio . Back again.
So many days ago I told you about to send config saved files from both units because I can find quickly (and solve to resend you) if there are some mistakes or software limitations, like obey regulations, carrier bandwidth, country set, etc.
The idea to move units to higher places ( like a simple pipe or pole) or move to left or right... still in mind.

[silviolmj]

Hi, ok, here is my files saved:
STATION: http://rapidshare.com/files/173147967/XS5-00156DB9FE3CSTATION.cfg.html

AP: http://rapidshare.com/files/173148098/XS5-00156DB9FE78AP.cfg.html

User and password default, ubnt in both.

[silviolmj]

So?

[guidonet]

Silvio, replace with new scripts. Start from remote location first.
This config allows better signal. but you really need clear LOS. Start adding one 6 meters pipe.

Why you can´t fix higher channels?... because you set Channel Scan List but no one added on scan list.
So... update Us when test this.

[silviolmj]

I've already see that, but i tried putting all the channel and its doesn't connect too.

Look, I configured my radio mobile but the image witch you send me, its not the same witch my prog gerate, what its wrong?

http://img152.imageshack.us/img152/5616/fresnelyh6.jpg

[WHT]

You have some incorrect data somewhere.

This is what I'm seeing

[guidonet]

Silvio, did you tried the new scripts?

[silviolmj]

I downloaded the scripts, but i don't know where to put it.
How to use the script in the program?

[guidonet]

Go to System TAB
scroll at Configuration Management section
click on "find" and search the new script downloaded and open it
click on upload
click on apply
... now NS restart with the new config

Remember to do first the remote NS

[guidonet]

Silvio, any update?
