What speeds do you offer?
How is the spectrum interference in your region?

ovkiller

I say: GO FOR IT AND PLACE THE RESULT HERE

ovkiller

so i can test it on my own risk? coz on 4.17 the wireless link disconnects from time to time (only 1 end is PC, other is 435GL). I mean, the feature is there but you cvan not guarantee if it is going to work perfectly? I am willing to test it becouse it does not work the right way at the moment....s...

ovkiller

I just saw it IS NOT

ovkiller

Hello uys,
When RouterOS v5 came out, there was no support for Nv2 on x86 system.

Is it still that way?

ovkiller

Try setting the HW Retries to 15...i had similar problem and now everything is fine.

ovkiller

Well...i will not enable it because....oh god...ofcourse I WILL ENABLE IT

ovkiller

Hello there,
After 3 years of using mikrotik for wireless links only i decidet to switch my Slackware linux with RouterOS.
Can you give me a hint about what do you guys filter on your machines? Which ports and why?

Will appritiate any hints and tips.
Thanks in advance.

ovkiller

what do you mean not using WDS.
I have a link with R52n with EoIP tunnel. If i use WDS is it going to drop some throughput?

ovkiller

Use N mode..
I have a stable link with 2x RB433AH + R52n cards - 5km distance - 95mbits real speed.
If you have more than 150 clients n the other side of the link , consider using RB800 or a P4 machine.

C ya

ovkiller

It is PtMP link.
There are around 22*2= 44 ends

ovkiller

Hmmm...no improvement. It seems that the best outgoing traffic from the wireless card is 11-12 mbits. It is strange as i remember 4-5 years ago i used 2x Edimax APs on 5km link and managed to pass 16mbits ptp...i hope that the CPU of the board will handle the same traffic or better :( Anyways, thank...

ovkiller

Hmmm...thanks Normis... i will change it to G mode and will post later the result.

ovkiller

Hahahah,
Reality really doesn't care

I will install in addition some Nano M2

Just was curious if i can reach better speed.
Thanks anyways.

And btw...why is better to use g only?

ovkiller

Hi there, I have RB433AH with R52H card using b/g mode and 16dbi omni directional antenna with 20 clients connected to it. What is the best speed i can acheave and is there a way to improve it with a new wireless card? Clients are nanostation loco 2 and Edimax access points with Grid antennas. Curre...

ovkiller

I recently finished my p2p 5km link. 2xRB433AH with R52n Cards 2x 90cm dual polarized antennas real throughput is around 80-90mbits. I have 170 clients behind the link and have pings to a max 20ms when using alot of throughput. 60cm dish comes small...i just had to replace them with 90cm to pass the...

ovkiller

I doubt it is going to work ...

ovkiller

Happy to help with the little knowledge i have

ovkiller

As i told you before, you have a hardware problem.
And your signals are not the same...so you have a problem with 1 side of the link.
Check antennas, Cables and cards (change them! ).
Nothing wrong with elevation...just change the equipment.

ovkiller

It will be really interesting.
I am planning something like that but in smaller scale.
Can't help you alot but i think that all will be very curious of the result.
Please post some info when start working on it.

ovkiller

Well...here is picture of 5km backhaul link with 2 60cm solid dish antennas and R52N cards on RB433AH

I reached better speed with 90cm dish

ovkiller

Just use the freaking frequency!
I used compilance test in the 6th biggest city in bulgaria with no worries and 5ghz superchannel in a smaller town.
I doubt somebody is going to find out

ovkiller

You may have a problem with 1 of the antennas... for 900m it is possible to see each other without antenna (cable only) Try changing one of the antennas and then other. I advice you to place more directional antennas (grid or dish. That way you have more antenna gain and you can make really good res...

ovkiller

all of us

ovkiller

Should be 40mhz.

ovkiller

And what antennas do you use on 8km link?
I use 60cm dishes but seems to be too small for that distance (5km)
I ordered 90cm and i am waiting for them now.... hope it helps to improve signals and CCQ.

ovkiller

Same with me...20-30-40ms ping on a 5km link. The links works good and suddenly collapses totally to 12-24mbits rates. After some time it regains previous state. i was really disappointed with the results... Tomorrow i will place the antennas higher and test for a last time. Hope for some improvemen...

ovkiller

Here are my tests on a backbone link: 2x RB433AH + R52n cards and 60cm dish antennas wit dual polarity horns. 5km distance band 5ghz signals are not very good: Tx/Rx: 71/68 CCQ: varies between 20% and 80% yesterday in the evening i reached tx/rx rate: 162Mbps-HT (real throughput: 80Mbits HDuplex ) a...

ovkiller

Do you use both chains or only 1?

ovkiller

My main problem is that the throughput is less than it was before (on v3.25)
I reboot by system downgrade

I wonder, how much throughput u guys get passed (real traffic) by a R52H card and 1 polarity antenna on each side (Board is 433AH)

ovkiller

Hello guys,
I recently upgradet to v 4.5 from 3.25 but after reading alot of posts with Nstreme problems i decidet to downgrade.
surprisingly i Can't! The device (RB433AH) Reboots and NOTHING! Still v4.5

Any ideas?

ovkiller

Hello, Is it possible to achieve more than 54mbits with 1 antenna and 1 polarity on each side. I mean I want to enable HT-extension but at the moment outside is snowing and i can't mount another antennas on the roof. Is it going to raise my speeds.

Any reason to think its from da cards?
Any reason to become damaged?

I really want to know why anything happened before buying stuff

ovkiller

Hello there guys, We established a point to point link over 12km. At the begining everything was fine and the signal strenght was about -70. We managed to deliver 35mbits 1 way. And suudenly after a few rainy days (after 4 months of no problems and a lot rain too) the link looked like this signal-st...

ovkiller

Hm...thanks for the replys guys.

i suspected that the limit is how much money u have

ovkiller

Hello guys, I had an argue with my network teacher about the maximum speed that can be transmitted on wireless and he told me (and the entire class) that it is 54mbits one way. So my Question is not "Can it reach more than 54mbits?" but what is the MAX speed you have heard or seen. Let's s...

ovkiller

Yep...crazy!

RB133 is...simple...use RB333...there 40-50 is good (maX) number

Thats my opinion

ovkiller

My friend...i have a private network with 130+ klients...i used to work only with wireless connections but let me tell u something... START CABELING. In the begining i found it hard to cable a village 3km x 2km ...but now when i have cables all around it...i have to work on that network ONLY after B...

ovkiller

well...i need that 30mbits...
maybe if i turn the antennas 90 degree to change plarity(not shure if thats the right spelling of the word... i mean we have horizontal and vertical right...if i change...)?

ovkiller

Hey guys...somebody just tuned in to my freq. a week ago before i go 5ghz-turbo i scanned freq. usage and saw that there is usage on 5240mhz. wheen i turned on 5ghz-turbo there was no usage at that time... today the link collapsed and when i checked freq. usage again i saw usage at 5210mhz (it was m...

ovkiller

Well...but CPU load never reaches more than 50%. I think it means that it is still OK on CPU POWER :) or i am wrong? Regards, Ventsi P.S.: What if i use turbo mode? I read somwhere in the forum that it will double the speed and lower the signal levels (but now they are 55db). P.S.: Turbo mode enable...

ovkiller

had the same problem and reached only 600kb/s

CPU was 100%

u know how i solved it??? bought 2 x RB333

. its expencive but it works great and it worth the money. THANKS MIKROTIK

ovkiller

yes i did RB to RB bandwith test. it shows 20mbits+. maybe there is a local issue that i will check in a few minutes. i started frequency-usage to check if there are other 5ghz wireless networks and found only 1. i will post the result after the test i am going to make. thx u guys. maybe after that ...

ovkiller

Well...just planted the card :) signal levels -50/-49 bandwith test shows 21-24mbits on UDP. real speed i reach by downloading from 1 server to the other = 1.3mb/s REALLY NOT ENOUGH. Changed channels later...almost no effect. any ideas??? clear line of sight...just 5km. 2x RB333 2x350mlw cards band ...

ovkiller

i used rb133 before

now rb333

when i used rb133 it was really bad link

100% CPU on 500kb/s one way

ovkiller

thx mate :) i was using 2x RB133/133c with 2x50mlw cards... 500kb/s MAX :( now i really need more speed so i am going to replace the 50mlw card with 350mlw. i think that maybe the antennas are not such a problem (or i am wrong:P ) for now. from other topics that i read here it became clear that the ...

ovkiller

ok...i will buy the same card theese days. I want to know is this the reason to drop the speed down. what exactly nstream does? do i have to enable copmpression on both sides?

thanks in advance

Thanks for the tip...when i change the cards i will write here the result but...right now i cant make it becouse i am 250km away to study...maybe in about 10 days i will do it.

I really appretiate the help u r providing me Jcremin. Thanks alot.

ovkiller

I have 5km link and 68dbm/80dbm (dunno why they differ) but i have managed to reach with the Bandwith test 6mbits...and this is the actual speed i reached when connected all clients to the linux machine after the RB.

ovkiller

OK...changed channels...the best i could manage to reach is 600kb/s and good ping (i mean acceptable for now...) but i need MORE bandwith :). 1 thing i noticed is that link works only at 5180 - 5280 MHZ... if i try 5700 it will not connect...is this becouse of 1 of the cards...(one of them is not at...

ovkiller

thanks

How to change the frequency of my 5Ghz link. I cant find where to do that from the terminal.

Can u help me?

ovkiller

well...ping gets higher whe bandwith is transferred coz u fill up the actual speed your APs can reach...

Yes i DID. But i am afraid about the PANEL antenna...is it possible? And maybe thi 4 meters long cable to the SATELITE antenna and the 3 meters cable to the PANEL antenna...?!!?! I a sure they can take much ore traffic...coz the test i made at home reached 24mbits one way. If i have half of this i w...

ovkiller

And i forgot... signal levels -67dbm/-80dbm (i am really a newby here and dont know much about all this but the links sometimes connects on 18mbits/12mbits and the rates must improve :) ) other problem is that even with low traffic passing between the RBs. ping is between 10-30. I used 2.4Ghz A Ppoi...

ovkiller

Aboslutley CLEAN line of sight...but a tested the connection in my room before deplying the RBs and i accomplished 20-24mbits traffic...I wonder is the problem in the Panel antenna or in the Cables connecting the RBs to the Antennas...
