replace that omni with a sector antenna, in general omnis used to burn your radio especially in noisy environments.

razvan_fzl

A solve is to use dishes of more dBi or/and to rise-up your antennas; I don't think if you do some settings you will gain more signal. If you use 2Ghz you will get a lot of interferences; I would try 802.11n (with 2xpair of separate atennas) that works nearLOS

Take a look in mikrotik's wiki

I had the same problem and would like to ask you if the signal was increasing when it was cloudy on both sides? First I used for this link SR5 with dished of 85cm and the signal was -81, throughput 28Mbps and then replaced with XR5 and dished of 120cm and the signal increased to -77. Use only dishes...

It's not a problem from pigtail, or connectors; I had the same problem, there is problem regarding the propagatin; I couldn't find a fix, maybe replacing with bigger antennas or/and changing polarization; sun also causes to loose signal. In my case also when it was cloudy the signal was excellent or...

razvan_fzl

For that distance it is possible to get that slow bandwidth, use antenna of 1-2 dBi, also recommend to use r52,r5h or XR5. Don't get complicated with other radios

Hi I intend to buy some mikrotik RB 4xx and would like to ask you what is the throughput on TCP of RB411A+r52 point to point considering that we have good LOS, SNR, CCQ. Is there any diffrence between RB 411AH and 411A in this case? I mention that I don't use routing or management of bandwidth, only...

razvan_fzl

Alvarion bs works with alvarion cpe. Anyway it is a limitation from the standard. If you want to manage more users, use pppoe (important for viruses), give priorities, make sure all the subscribers have at least 18dB SNR, CCQ>60%, use a powerfull board, recommended x86, P3@1000mhz intel.

razvan_fzl

you can buy separately the connector and make a pigtail or try www.aerial.net

I don't want to make advertise on this forum so if you really want N, don't wait for MT.

razvan_fzl

Try it before argue;

razvan_fzl

Try Ubiquity complete solution, it has some bugs but it works. When MT would produce their own mimo minipci card then you should use it; in my opinion MT tries to release a very stable version for mimo; You can use MT for your BS and for backhaule other line of products.

Still waiting...

razvan_fzl

It is possible to reach 45Mbps in turbo (40Mhz channel), but you need good SNR, good ccq (>80%), no interference... I recomend using XR5 or UB5

razvan_fzl

Looks like nobody would give an adice other than buying routerboards. I will buy one and try

razvan_fzl

Hi, I want to buy one intel MB ( this mainboard http://www.intel.com/Products/Desktop/Motherboards/D945GCLF/D945GCLF-overview.htm). The question is that if it will work with XR5 minipci, because on certain MB didn't and also experienced problems with minipci to pci convertor, it works with pcengine ...

I intend to replace some p3@1ghz with rb433ah because of low power consumption and because I have only one PCI and want to do a n-strean dual. I mention that I use it as a transparent bridge without routing. Do you think it would be reliable? which is better?

razvan_fzl

Hi, Can u send me an example. I also use bridging between eth and wlans and I would like to use ospf. I use the following: linux router ---[Mkt(eth+wlan1+wlan2)]----cpes(rtl8186). I read from wiki but it did not work.. I would appreciate your answers, meanwhile I get an answer I will be trying to so...

Hi, I an admirator of mikrotik... I use all kind of configuration! I have one problem that I solved it and want to expose it to everybody! I use the following configuration: 1P4@2400Mhz, MB gigabyte, 256Ram DDR, 3 minipci R52, one CF SANDISK witk MT 2.9.51! They worked perfectly, but after a while t...

razvan_fzl

Hi, I wonder what is the best suitable miniPCI for AP mode, for sectors with a few meters of low loss cable! Is R52, is R52H? or SR2 or Senao? I am using R52, CM9 and senao and it seems that R52 is working well, the other one has some problems with cpe! I mention that for CPE I use Ovislink, edimax ...

razvan_fzl

I don't think there is a bad card or ethernet, because when I connect my laptop or a cpe, it works perfectly... maybe a cpe is bad. I am waiting for suggestions, except replacing all the cpe

razvan_fzl

I have other problem, I get great delay even on lan but when I unplug the antennas the ping is getting to normal <1ms. I mention that the traffic is <700Kbps and the number of packets is <100 maybe 50. Please help

razvan_fzl

Total output <2Mbps
150 Tx , 150 Rx Pachets
I use only bandwidth limitations... so I don't think it is necessary to limit number the connections yet. Is it possible that a cpe from a custumer to generate such ping?

razvan_fzl

CCQ is over 70 at every cpe. I think that I will replace r52 or cm9 with something else

razvan_fzl

I found a clinet connected using an ovislink, the signal level was low and afer disconnecting it worked well for a while... but the ping is still huge sometimes

razvan_fzl

It worked perfectly for 3 month, I checked the cables, antena... replaced computer, upgrade to 3.1 version and then downgrade to 2.9.50... I think there is a problem from my clients, they use alfa AWA 608 or airlive or edimax based on 8186. I mention that the ping is great even when the traffic is b...

razvan_fzl

I still have problems with great ping, for a while, I limited the traffic, but the need of greater speed is mandatory... Sometime I looked to graphics and it was really low but the ping was very high. I mention that I use b/g standard and I use channels 1 and 8 for the sectors

razvan_fzl

it might be a bug or maybe the antenna is not made for that frequency, I have the same problem... but I didn't find a sollutin; one explanation would be, the more frequency, the less signal. If you solve this problem please send us a response

razvan_fzl

Hi,

I am using many systems based on mikrotik, but I am not sure how to stop the broadcast storm created by windows? Any advices?

razvan_fzl

Overall Tx CCQ is slow

is varying from -45 up to 89, but the signal level is from -54 up to -80

Hi, I am using the following config: 2 sectors@17dBi, 12meters of LMR400, 2 miniPci R52, software: Mikrotik (leve 4)2.9.49 and P3@1000Mhz, 128MB Ram, Compact flash! I set-up channels 1 and 8 for each sector, there are about 20-25 users on each antenna, but the problem is that during evening there is...

razvan_fzl

you must find a "tunnel" or if u would use directional antennas on both sides, but link will be unstable, 900Mhz may help

razvan_fzl

I got 71Mbps with 2pc p3 @ 866Mhz, 2xR52, 5Ghz Turbo! Good luck

razvan_fzl

Did you try trubo+nstream? I think you can use 8 minipci in bounding mode but you may have sau distrosions! But I think that you need licensed frecuency, you may try 3,5Ghz

razvan_fzl

I solved the problem by replacing rb11 with other adapter from other vendor and works fine!

thanks all

razvan_fzl

The problem is that XR5 needs 3.3V, not 5V

razvan_fzl

Hi, I just bought two piece of XR5 and I have some problems with. The system configuration is: celeron@2667Mhz, 512ddr2 Twinmos, MB: Gigabyte, RB11 Power Supply: ThermalTake 420W pure power, Mikrotik 2.9.45 and 3.0 rc! The problems is that the system reboots spontaneously . After I have read on this...

razvan_fzl

First of all, it is important the quality of your dish (90 cm is enough for that distance), pigtail... I suggest to use only XR5 or SR5! You will get even 25-30Mbps, but is dependent of you configuration of your system (cpu, ram, etc)! Also a good LOS is needed!

razvan_fzl

I have already did all this, and there is a good LOS

razvan_fzl

I use that configuration to make a bridge (wds) between 2 points ( 4Km ) of 5Ghz. The problem is that the signal fluctuates between -76 up tp -86! I mention that the noise is -102! What may be the problem of the singal?

Best regards

razvan_fzl

I tried to replace SR5 with another miniPCI, but this time r52 and the signal was worse! I cheked all the cables, connector again and again, changed the polaization without any result! But the question remains, why did it work just fine??? I hope that somebody will help, I will even pay if somebody ...

razvan_fzl

already did without any result

razvan_fzl

There is no inteference

razvan_fzl

Nobody had problems with SR5?

Hi I used an omni antenna with a certain ap and I decided that is time to use a PC with 2 sectorial antennas! The configuration is: p3@1000Mhz, 2R52, 2 sectors @ 17dBi! I made a bridge between ether1+wlan1+wlan2! The problem is that the ping is very high o alternates 2-8ms with time-outs! I replaced...

razvan_fzl

I have another question: I made this access point for outdoor, so I needed to use suplimentary coolers, one of them is oriented toward the R52s, this may cause a magnetic field that can affect the radio, because it seems to my the signal level is pretty low? And another question is that that I use a...

razvan_fzl

I got the same problem can you tell me if you fixed it?

razvan_fzl

Hi, I use the following configuration to offer internet access: P3@1000Mhz 256MB ran 2x R52 miniPci 2x sectors 17dBi The problem is that the latency is very high, though there are only 10-12 users on each miniPCI and there is no huge traffic and also system resources are 90% free or more! I made the...

Hi, I have the same trouble like others with dc++ or torrents because of the limitation of the hardware. I intend to use a P4@2000Mhz, 256MB with R 52 and a 12 dBi omni antenna! For the moment I use ZCOM ZG 7000 and crashes when there is a considerable amount of data! How much will improve P4 the st...

razvan_fzl

Hi,

I need a link of 30 Km! I bought two piece of SR 5, 2 P4@1500Mhz! I intend to use dishes of 120 cm offset or should I use prime focus?! How large will be the bandwidth? I will appreciate also the configuration of the software as an example!

Best regards

Hi I have just bought the devices from the title and what I want to is to use 2 antennas, one R52 + Grid 24dBi for receiving the signal from a certain AP (base stion) and with the second, NMP 8602+ to use with an omni of 12dBi as a new base station! I have connected the R52+grid to a certain AP, I c...
