MikroTik

ivaring

Guillermo.

En realidad cuando conectas Mikrotik con otra marca, configurandolo como Bridge, tenes que incluir las interfaces wireless y ethernet en el bridge sin WDS, y una vez registrado el cliente, la interface Wireless te muestra el mensaje R=Running.

Salutis.

ivaring

I've one question/doubt.
Why someone would use NAT while bridging one net?.

Regards.

ivaring

Well, actually I think that speed is not so affordble with that devices.

If u are looking 4 something without Line of Sight, u'll have to migrate technology.

Regards.

ivaring

But that 3 first values are talking about a vendor, why did u wanted to block or permit a vendor?.

Regards.

ivaring

everyone uses wds? I thought this would be very common, anyone NOT using WDS for a bridge??

Well, I use Bridges without WDS, but only when clients are not MTKs.

Regards.

ivaring

Infact, what is your distance?.
I mean, with that power u add much noise if u are close.

Regards.

ivaring

1) WDS protocol is required if you want to establish link between two AP and allow clients to connect to these access points. 2) Make sure you have enabled SNMP on 'snmp' menu and correct SNMP community is used, other configuration and settings related to Cacti. Point 1) is true between 2 Mikrotiks...

ivaring

yes i want to connect clients form that side. so is it possible to make link with same base station or not? or is there any other solution? i hope u will give me quick response. Well, that's a common situation. You can configure your Mikrotik as an ap-bridge and then register your clients to it, I ...

I'm saying that after I upgraded to 2.9.44 my problems went away.

hello friends i connect my AP to AP using WDS static mode.my all access points are working fine but i have question i m already made point to point link with base station and i want to make one point to point link with other side with same base station so how can i make that i hope any one help me ...

ivaring

Hi there. Would u post your logs please? (I had these problems in past, solved now). Thanks. Hi Ivaring, I managed to fix it and I'm not sure what did it. Maybe 2.9.44??? I'm running RSTP, before I was having 5 to 6 disconnects a day and now maybe 2 a week :) The logs are exactly as the poster says...

ivaring

You say that u have clear LoS.
Your signal power is Okay.
Distance I've from APs to clients are not bigger than 1Kms between Mtk and Edx.

Maybe u can try upgrading your Edx firmware.

Regards.

ivaring

I also used Edimax Clients (antennas and APs), and as first experience, I also had so bad signal to clients.
Then the problem was trees in the middle and too much power on MTK.

Regards.

ivaring

Hi there.
Would u post your logs please? (I had these problems in past, solved now).

Thanks.

ivaring

I've same problem.
I see other end from my antenna and viceversa, but WDS is not going up.

Maybe STP problem (with version 2.9.38) with newer versions of RouterOS......

ivaring

How right I am. A customer with a -61dBm signal and SNR of 30 unplugs their radio and plugs it back in. EVERY radio on the AP cannot be pinged or has high latency for 20-30 seconds. How is SNR the problem? Also, every other AP connected to the switch sees the same issue. SNR has nothing to do with ...

ivaring

Beware of your RouterOS version.

ivaring

AP will let u register more than one client.
To create Transparent Bridges, u must include some interfaces on a virtual bridge interface.

Regards.

ivaring

Hello.
Mmmm, but I zink if u put your antennas in Turbo Mode, I'm not sure of being an usual application of NStreme, because one antenna is Tx and the other is Rx.

Regards.

ivaring

Hi there.

ap bridge for multiple clients.
bridge for only one client.

Regards.

ivaring

Thanks Janisk.

Actually that link is what I usually used in past, but, with newer versions of RouterOS, it seems not to be yet valid at all.
Maybe because STP or RSTP.

Regards.

ivaring

I had same problem in past, I fixed it enhancing my SNR ratio (2 much signal power).

Regards.

ivaring

Hi, thanks 4 the link, could u send me please an email with that PDF?, because I've problems downloading it.

ivaring@hotmail.com

Thanks again.

ivaring

Hi there.

I've similar problem, but it's only with newer versions of RouterOS.
I'm trying to take a deeper look, because I think it could be something related with STP or RSTP.

Regards.

ivaring

Thanks 4 your answer. Actually, the first ptp configuration I used was taking this link as a reference, and always worked very well, I've several functional Mikrotik ptp links similar 2 this. http://wiki.mikrotik.com/wiki/Transparently_Bridge_two_Networks Today I do some other configuration but, eve...

ivaring

Hi all.
Does anybody knows about differences between new versions of OS and older versions talking about ptp links?.
I mean, when old OS I was able to do a ptp link configuring an bridge and station wds, but with newer versions, wds bridge is never coming up.

Thanks.

ivaring

The problem is not SNR related. As has been mentioned, just having a client associate causes the problem. The more clients connected, the longer the timeout or high ping times. We are seeing up to 20 seconds and longer where the radios can't be pings. Another frustrating problem is that if you have...

ivaring

Don't want to be ofensive, but best hardware you could use, is a 50 m piece of sftp. Else, if you mean radios, look in the forum for some tests, you could use any indoor configuration, to achieve anything between 6 mb/6mb (duplex) to 30 mb duplex, on that distance. If you are absolutely shure you w...

Hi there GWISA. Actually, as I see, CIR is not dependant on number of clientes, it would be traffic dependant instead, but number of clients of course could be another question, absolutely.

ivaring

Well, it seems like nobody has done this question first, really strange, but, it's true.

ivaring

Thanks 4 your answer, but actually queues are not telling u about CIR. CIR is "speed" that some device can develop, independently of its features, so, queues have other functions. Thanks anyway. An example. Some Canopy product tells u that its speed is 512Kbps, its burts speed is 768Kbps a...

or use V3 beta - there you can bridge wireless-ethernet

Well, actually with 2.9 is posible too. I'm doing it.

ivaring

GPS is useless for antenna alignment - stick with the compass, and make sure you have taken the specific magnetic declination for your area into account... Well, actually not so useless. There are equipment that surpass any interference my mean of GPS, so, GPS is very very usefull, actually. Regards.

ivaring

Hello.
Thanks 4 your answer, but I don't understand your point, I mean, CIR is a basic definition of a compromise regarding rate benefits.

My question was regarding Mikrotik compromise in this sense.

Because Queues are used 4 priorities, not 4 CIR.

Thanks.

ivaring

Hi there.
Does anybody knows which could be the CIR in the Mikrotik cards?.

Thanks.

ivaring

Talking about disconnection.

I suffered mainly two problems.
a) trees disturbing registration, so, moving antennas was the solution
b) excesive power on antennas, so, N/S ratio was too poor

I solved this problem, today not disconnection messages since 3 months ago!

Thanks.

ivaring

Right!.
If you configured in past that SSID, your PC will be always seeing that SSID.

I had that problem solved.

Regards.

ivaring

Also there are some kind of spectrum analyzer.
I'm thinking of buying one of that, because I'm having a lot of environmetal noise.

Regards.

ivaring

Hi.
You can try magnetic isolation with some kind of alluminum watertight box.

Regards.

ivaring

I agree with u, that's what I'm using.

Regards.

ivaring

Thanks Andrés.

You also have take in account that any of those security profiles makes throughput lesser, I use MAC filter anyway.
I have one 6kms ptp link and another (for now) of 2kms, same.

Regards.

ivaring

Actually I'm using Mikrotik RB522 and 512 to link several locations.

Regards.

ivaring

Hi Andres.
How is your link?. Does it works well?.

I'm asking u because I'm having several of this links right now, to change oppinions.

Maybe, as I'm also Argentinian, we could share some information about our links.

Regards.

ivaring

Hi there.
I think you could have a lot of power, that is also my problem right now.
I'm trying test with smaller power.
Give a look to your SNR.

Regards.

ivaring

Well.
I suppose that there isn't any new idea around here.

Thanks anyway.

ivaring

Have u ever got "extensive data loss" messages before disconnection?.

Thanks.

I see excessive data loss as the reason of disconnection.

Do you have any experience about this message and possible solutions?.

Thanks.

We are testing a 112 and can only get around 0.5 Mbps. The AP is a 532 which gives decent throughput to other clients. Atheros chipsets in AP and in 112. We tried b and g modes. SNR is 30.
