MikroTik

YappaDappa

This is a question for my fellow professionals using Mikrotik in their infrastructure. My company has the opportunity to co locate equipment in a data center to connect a 10Gb fiber link 90 miles away to our NOC. It is our hope to put two MT units in the data center and two in our NOC in a redundant...

YappaDappa

Running out of ideas troubleshooting this. Replaced cable, replaced ends. hard set speeds, also tried auto negotiation. Any suggestions. This is connecting to a UBNT AF24 BH.

I did and it was written for 2.9, unless you know of a link that has info pertaining to time.

YappaDappa

and now, 8 years later, there is almost NO defense it seems

YappaDappa

Hello all. My question is about the time setting while queuing. There is an option to set TIME under SIMPLE QUEUE, GENERAL. If I enable a time schedule for a client, does it disable access during this time period, or give them unlimited access?

Thanks!

YappaDappa

with money as no object and mikrotik as the solution, how would you build the fastest most reliable backhaul for a 3 mile link, top of a hotel to a mountain. Your internet capability is 90Mbit.

Thanks,
Ron

several of us started a thread regarding the advantages of MT over Motorola Canopy. It has now been removed. The admins of this forum have just cast a shadow of doubt on their product by not permitting discussion of such things. Is there something you are afraid of?

YappaDappa

I thought I tried that, I will experiment today. Thanks all.

YappaDappa

Thanks for the tip.

My RB230s keep the date/time after reboot. Only the rb112's are giving me a problem.

I don't suppose you have a script handy to do this? I would do it if I knew how. Thanks.

YappaDappa

Hey fellas,

my RB112's with 2.9.38 will not retain time/date after a reboot. have you seen this before? Any workaround?

Cheers!

YappaDappa

let's start a new thread

YappaDappa

this is really a matter of us setting up a standard for our field installers. Does anyone else have a particular standard that you like to meet?

YappaDappa

YappaDappa

Noise filters? Where do you purchase, and do you only place these on the APs, or at each station suspected of having interference issues?

YappaDappa

I'm sure this could start another thread, but in short, I find the advantages of Motorola over mikrotik are: 1) far easier to install 2) more weather resistant (extremes) 3) more reliable/consistant (fewer dropped packets) under load Disadvantages 1) Terrible support - worse than MT. You will comple...

YappaDappa

Well, I really haven't dropped Cnopy. I use both. It really comes down to cost. A rb112, CM9, rootennas is about $130 less that a subscriber module, plus I have a lot more control over the clients use, including virus filters, multiple bandwidth queues throughout the day, etc. But I do find some thi...

YappaDappa

Hello fellas, How are you updating all your field subsciber units (ie, RB112's) en masse? Before we switched from Motorola Canopy when there was an update, we could schedule every subsciber to automatically update to the latest firm upon connecting to the AP . Does this MT community have something s...

YappaDappa

What is your recommended (acceptable) ranges for: Signal Strength (-65 to -75) Tx Signal Strength (-50 to -70) Signal to Noise (<20dB) Tx/Rx CCQ (>50%) We use Mikrotik to Mikrotik, and have created our own "best guess" values based on experience (our guess values are in ()), but we really ...

YappaDappa

Hi All, We just got a half populated DS3 installed (13T1). We are looking for a wise solution to backhaul this bandwidth to our tower 1.5 miles away. Dual Nsteme sounds like it really shines for long distances, but is it overkill for this situation? Based on your experience, please share your though...

YappaDappa

Hello Mikrotikians!

So, we had a RB230 get struck by lightning. We replaced it with identical setup (luckily we happened to have a spare). Problem is this:

Although all clients connect well and can ping ip addressess, and resolve web pages, we cannot access any web pages via a browser.

Any ideas?

YappaDappa

certain it was not us, because when we set things up and when they work, we leave them alone. I don't like tinkering. And things worked for four days beautifully! Well, been several days now, still going strong after the reconfiguration.

Hope it was a fluke sten.

YappaDappa

when I tested from p4 to P4, I got 6.5-7mbit both as average. So, an improvement, and pretty much all we will need for this sector. thanks for your suggestions, I will consider different antennas. I also played around with the rates, and the antenna power. I locked into 12, and manually adjusted the...

YappaDappa

Mikrotonians. We have successfully setup 5.7 WDS bridges to use for short range backhauls. Strength around -69. Been up for 4 days. for the last two days, we have spontaneously "lost" the bridge. no explaination, no cause and effect on our end, the two devices simply stopped talking to one...

YappaDappa

does this RB use the RBfirmware designed for the RB500?

YappaDappa

Hello guys. We recently bought a pair of RB 112 to use on a low volume backhaul to a nearby (2 miles) tower. we are using CM9, osL4, 2.9.18, 17dbi "backfire" antennas on 5.7. The backhaul seem to work just fine. I am happy about consistant 4-6ms ping times. However throughput is another st...

YappaDappa

tried this rule, and people instantly had problems with complete page resolution. Any ideas?

YappaDappa

what firmware are you running?

YappaDappa

will applying this rule to say, 50 queues have a negative impact on consistant speeds used for gaming and streaming?

YappaDappa

Hello Mikrotonians! I am redisigning my network. I am no longer happy with my erratic ping times, and inconsistant service. So I am thinking of reducing the number of devices traffic passes through. Currently: 3xT1-->Tasman 1004 router--> Cisco PIX 506 --> Mirotik 2.9.18 used for bandwidth shaping -...

YappaDappa

alot to consider. Of course, nothing says I won't benefit from locking to 5.5, which, according to this information, is still going to be way better than my locked down speeds of 1 or 2Mbit. Should be interesting. I'll post the results from my first sector soon. Thanks all.

YappaDappa

Great explanation. Thanks for taking the time.

I will try your recomendation on one sector, and see how things go.

YappaDappa

I am using the MT as the AP. I am using the senao for the CPE.

YappaDappa

mostly windless conditions

YappaDappa

How do you monitor signal strength and speed ? I can monitor bandwidth consumption via MRTG, but I use senao CB3+, and they, very unfortunately, do now support SNMP2 that I know of

YappaDappa

Hey folks. I've got a strange one. In the past few weeks, I've been getting support calls regarding poor or NO connections at night. most say, uncollaborated, that is starts around ten PM. Nothing has changed on my network, other than the latest firmware updates. I'm at a loss. I don't know if it's ...

YappaDappa

I have 6. all about 3 miles apart (two are on a ridge, and can see neighboring villages) I guess my point is, if you are in a low traffic area, and need great distances, AMPS work fine. I am about to determine if our newly crowded RF environment is what is causing problems in the main part of town. ...

YappaDappa

just the answer I was looking for. Thanks.

Since you are so far away, I will toast to you my next night out: "To CMIT, a genuine and valued Mikrotikian!"

YappaDappa

well, after a week of using traffic shaping for P2P, I am going to drop it. I find that while bandwidth is preserved, performance for everyone is poor. For instace, on bandwith tests, I find the results deviate by 20-30% when enabled, and only 5% when not enabled. What a bummer. Could it be I have t...

amps have been on my mind recently. I read these forums often, and I see it mentioned over and over again: Don't use amps. You see, I do use amps. 1 watt bi-di hyperlink at all my locations. When I first got into wireless, I found that it helped me get installs done fast. I live in a 5 mile wide X 1...

YappaDappa

interesting. we locked down to 1,2 for two reasons. One, it seems to work well as a built in rate limiter. Two, when we set to 11, pings sometimes go haywire, and in some cases >2miles, we start to see reregistrations. Does that make sense to you?

Frag thresh: 2346
RTS: 2432

YappaDappa

I noticed that my antenna gain settings are set to 0, but all seems to working fine. Does anyone know if this auctually has an impact on anything? If I were to enter the auctual gain of my antenna, say, 15, will it decrease output/sensativity? Any insight will get you a beer salute!

YappaDappa

I am using senao CB3+ for CPE. I always set rate to "1,2Mb"

YappaDappa

well done fellas. Thank you.

YappaDappa

perfect. And default authenticate? Simple explanation? and will it provide any relief on my overstressed prism cards to have it off?

YappaDappa

Hello Mikrotikians -

I have seen several times in the forums that some people suggest turning off default forward, but no one has explained why. Can you help explain?

YappaDappa

Hi.

140 users/3 sectors =~47 users per AP. I have 45

So, you are not overloaded?

YappaDappa

that sounds like I wouldn't want unlimited option for limt-at then, correct?

YappaDappa

Hey guys. I have what I suspect to be an overloaded sector. I am running a routerboard230 with 1 200mw prism card with latest firmware + 1watt amp. I have 3Mbit of bandwidth to share with clients. I have 45 users. Performance stinks. VERY inconsistant. I suspect this card is over stressed. How can I...

YappaDappa

I think I understand a little better after researching more. the first is the Max limit, the second, the CIR. In my case, I want their CIR to be whatever is available up to the Max limit. So, I am guessing I should just leave the CIR to unlimited?

YappaDappa

on general queues, using winbox, and 2.9.13, one has the option to select target upload and target download of say, 512k on the Advanced tab, you again have the option to select target upload and target download. This is confusing me. should I just set this one to unlimited? What is this one really ...

YappaDappa

I understand collision domains a bit. Are you suggesting using vlans per routerboard or per user? Isn't it impossible if ultimately all connections reach a single backhaul?

YappaDappa

Hey, thanks Bill, Here's a little more info: NxT1 (3Mbit) backhaul each user limited to 256k, with 30 sec 1M burst P2P limited to 64/128 from 7AM-midnight, then opens to full I am using a 5.7 20Mbit motorola backhaul I use Senao CB3+ to connect to the MT bridged So, what can be done to reduce networ...

YappaDappa

I am having this problem too. I am currently piping 3Mb to about 45 clients. All are rate limited. I rarely hit >70% bandwidth consumption. Problem is this: ping times and speeds are all over the map. In one speed test I could post a 214, the next a 600. Ping times can go from 3ms to 300, or no repl...

YappaDappa

YappaDappa

Do you suggest that lowering basic rates improves constant performance?

YappaDappa

well, implemented the recommended filters. Works like a charm. Thanks man! But it didn't resolve my wireless issues. Ping times are all over the map, and page resolution is very slow. However, throughput seems to be right where I rate limit. Tonight I am going to try downgrading a sector and evaluat...

YappaDappa

I'll test this today. This community is lucky to have people like you.

As an added filter do you recommend limiting connections for subscribers? If so, how?

Thanks alot amigo!

YappaDappa

wow. so easy when you know what your are doing! I just tested this and it works great. Ok, one more variable. say I just want to give em 64k for P2P during the day, and unl at night. Is this possible?

YappaDappa

is it possible to only block P2P from 7AM-11:59PM?
Also, I heard it was better to just let P2P barely leak through, instead of blocking it fully. What's your take?

YappaDappa

I have read the manual. Thank you. Coupled with a max, doesn't this create a range? Now, to help you better understand, we have limited bandwidth. Let's say I want to give you a minimum 1Mbit connection. But if 1Mbit is not available, do you simply wait until it does? (as the world turns) This is wh...

I am wondering what most people are setting this variable at. It seems to me that the lower, the better. Am I wrong? I have set mine to 32k. But something seems laggy on my RB230s.

YappaDappa

after performing these recomendations, I got an equal number of connections increased as I did decreased. odd Also, MT wrote me and tells me "We recommend to left 'rate-set=default' configuration." Although, it is very unclear why. Anyone else play with these settings? What has worked best...

YappaDappa

quite frustrated.... I love the MT platform. Literally saved my WISP operation with it's highly affordable and practicle features. However, I can't seem to get P2P filter working correctly. Specifically Bit Torrent. I don't want to kill it. I feel my customers can use these programs, but as long as ...

I appreciate your response. I am testing dropping the rates to 1,2,5.5 and basic of 1. right off the bat, when I did this, I saw signal strength drop to -100 on about half the clients. I suspect this is due to inactivity, and perhaps once they start using it again it will give us real numbers? Do yo...

We populate RB230 boards with Prism cards, running 2.9.7. We pipe out two T1 lines, so our users can never get more than 1.5Mbit down or up.
