i can't get it work, wen I add a router and press submit it comes a blank page! what is the problem ? I use 1.30

Thanks Remus

remuss

I suggest u to set manual data rates 54 and 48 and for backup 36; use default by tx power

maybe u have luck

Best Regards Remus

remuss

for 6km I suggest you use a 5Ghz link mini pci R5H it's ok for this distance and RB411; A good question is what capacity you need ?

remuss

or u can disable ftp and other services that u don't need, and enable them only wen it's needed

Best regards Remus

remuss

ok great that it's the link is going now

Best regards Remus

remuss

give us more information routeros version channels how is the link configure, and that we can figure all what is about, is there a antenna near the ap or some info that could lead to the cause

Best regards Remus

remuss

maybe You have made bounding and set iti to be for backup link.

Best regards Remus

remuss

All are right they are different band there should be no problem but they create electromagnetic wave that can affect; I have the same problem near me at 4m is a GSM tower and it affect my throughput, but it is not significant because I have XR5, you must test and see.

Best Regards Remus

remuss

what are the cards that you use; what is the distance of the link; what is the SNR; we need more details to judge your case.

Best regards Remus

remuss

you may try to use different channels one 5800 and one 5600 or something like this; between the channels U must have more that 150 Mhz difference.

Bets Regards Remus

remuss

what channels are you using ? use channels with differentiation of 150mhz i had that problem and I used different channels and it worked for me.

best regards Remus

remuss

i don't think that this is possible but u must know what antenna is connected when you have assessable the equipment.

Best Regards Remus

remuss

ok I will try and keep U up to date

best regards remus

remuss

my goal with the actual instalation 70 Mbps Btest TCP

remuss

In you opinion what antenna should I use; have someone tried http://www.vesuviustreamline.com/product/trans-techno-dual-polarity-31dbi-cassegrain-antenna.html; Could this model of antenna increase the throughput ? I want your opinion or shoul; I go to an offset 0,9 antenna ? Thanks in advance !!; wh...

remuss

I have tried but wen I go 1 db in each end the signal go to -56 and CCQ is arround 70% and I can't get more throughput, one end is near a GSM tower and I think it's not good

Best regards Remus

remuss

I'm not interesting in udp traffic, I want more tcp traffic that is why I have asked for the signal strength because I thought that with this signal It ' will go 70 -80 Mbps because I have x86 system and I'm not hardware limited.

Best regards Remus

remuss

ok I will make this changes tonight and I keep you up to date what happen with the throughput .

Best regards Remus

remuss

Setup: 2 x86 systems dell optiplex; intel 3Ghz CPU, one Offset 1,2m , one parabola 1,5, 2 feeders interline, 1,5m LMR400 pigtail, and the best XR5 :D, the channel is 5800 turbo, nstream on, compression on; http://img222.imageshack.us/img222/4711/signalstrength.jpg http://img148.imageshack.us/img148/...

remuss

I think in either 1 or 2 variant the interfaces will not be the same you must reconfigure the hole RouterOS; better to test install 3.22 and import you will see what is happening; But I recommend to do the configuration again you will be sure that this will work well, in less time.

Best regards Remus

remuss

I have tested and I confirm that a offset antenna 1,2m is more efficient and better performance, in compare with parabolic 1,5 for my link on 25KM. Thanks anyone for effort to respond to the topic

remuss

first off all upgrade to the latest version RouterOS 3.22 and do the setting again you have missed something; the settings from the site are correct I use them to.

Best Regards Remus

remuss

use Brazil and you will be amazed

remuss

yes You must reset to the factory settings and to make the settings of the router again; I think it;s the only hope

Best regards Remus

remuss

yes i understand but for long links is XR5 better in performance ? throughput ?

remuss

I understand that I would do so but 2 friend of mine engineers sad that a offset antenna is more efficient, indeed is not that easy to align. and the interference what is better ? offset or parabolic ?

remuss

nice and can you give more details what is the signal strength, CCQ etc

remuss

the PTP link will be for 25KM
what is the best choice for antennas; an offset antenna or a parabolic antenna ? the feeder that is used is Interline 5Ghz feeder and in one end at 4m is a GSM tower (this I think is not good)! Please help. What would be the best choice ?

Best regards Remus

remuss

what is your opinion of the new R5H from mikrotik, have someone test it ? please share your results with us; I want to buy 2 card for a ptp link of 25 km and I want user opinion who have tested it, how it it in comparative with XR5, I have seen the tiktube video but I want other opinions too. Best r...

remuss

what is your location is near you a GSM tower; I have the same problem after COSMOTE have upgrade their tower what card are you using; what is the distance of the link ?

remuss

is there a way to detect what kind of interference I have in my zone ??? could a GSM tower be a source of interference ? if he is on 1200Mhz ? I have 2 identical systems but my signal strength differ why ? how can I resolve this problem ?

With respect Remus

remuss

I would investigate what is the strength of signal with scan or snooper from the client side and see maybe there is some noise

remuss

I simple don't understand this I have noise floor -101 ;-102 but Overall TX CCQ is 25% - 32%, could this be from the fact that I have put manual TX power to 20dbm; how could I improve this ??? have anyone any Idea ???

remuss

could a GSM tower that was build near me 5 meter affect my signal because this end signal was -90 I must to set manual tx power to 22 to get it to work again.

remuss

I wait the cables, but by than how did you say galaxynet should I configure the wireless P2P (now they in transparent bridge configure), what is the best for maxim speed, ap and client ? Thanks in advanced.

Best regards Remus

remuss

1 more question the maximum output power is 25db ? should I set it to manual TX Power and set it to 25 ???
10x very much for the indication I let you know what happened, this week I switch the cables and the pigtales the XR5 next week I don't have money now.

Regards

Remus

remuss

on this distance I rather use 5GHZ because, mobile phones, microwave, all home wireless is at this frequency of 2,4 Ghz. At 5Ghz at my experience if you need 2mb the link will be excellent with al most 3ms ping.

Regards

Remus

remuss

the distance is 25KM what should be signal to noise ? I will change the minipci to XR5 and make the pigtails shorter, and change the cable with LMR400 how did galaxy say

remuss

galaxy thanks for the replay what is your opinion about this minipci ??? http://www.wifimarket.ro/detalii-produs-48-Xtreme_Range_5_600mw_80211a_mPCI.html could you explain me what configuration should I use I don;t understand (router ?); I use this antennas to make a PTP link that all no routing or ...

remuss

Hi all; I need an advice; First off all my configuration is: 2 computers dell optiplex GX270 with 2,4Ghz CPU; 2 x CM9 mikrotik 3.17; 2 x parabola 1,5m with feeder in the middle; 2x ufl to RP-SMA cable 30cm and 1,5M RF240 cables; this configuration and on the mikrotik there is 5GH turbo mode enable a...

remuss

but how do I know that pe channel is ok from the CCQ ??? and what does it mean ??? should I use ver 3 ? it's beter on wireless comunication more stabile ? please explain it to me

remuss

what means Overall Tx CCQ around 45% (interferance ????)I use routeros 2.9.27 would it help if i change to v3 ?
what is the best CCQ % as low as possible ??????????
sorry for my english
