Thanks for confirming that I am doing everything correctly and that this is a software bug.

You are not doing anything wrong as far as I can tell.I don't feel like i'm getting anywhere working on this on my own, so if anyone can help me out that would be great
When will it be made available?New firmware will be able to mask some of the spikes
How is this coming along?Specifications are correct, any issues you might be seeing, are depending on specific conditions and ripple noise from the PSU. We will make software upgrade that does some output adjustments to compensate for this noise.
Thanks for this info.positive end of capacitor soldered to positive end of onboard capacitor C14
negative end of capacitor soldered to negative ends of onboard capacitors C34 and C59
That's nice to hear, as, in their current state, all our RB750UP devices can't fulfill they main purpose and we had to go back to using DC splitters and individual POE injectors.we are working on new controller firmware that should remedy these problems.
Any updates?@normis: Wiki was first place where I've looked at Could You give me a link to ROS 5.15rc1 (e-mail or PM).
Edit: OK. Got 5.15rc1. I'll try to test it in the same location where problem showed up.
I can confirm that there is huge performance improvement in ROS 5.3 even compared to 4.17. So do not downgrade, it's better to wait few days and upgrade to 5.3.
Life is nice again
Don't forget another $15 or so for case and power supply + labor for putting it together.
A word of warning, don't cheap out like I did. For $30 more, you'll get these features if you buy RB450G:
I have been told that the reflectors don't work for dual polarity type devices.the focal point doesnt change by frequency its depend of the size and form of the reflector..Not to go off-topic, but how do yo calculate focal point as it's slightly different for each frequency(band)?
If you are using bridges, be sure to enable IP firewall in the bridge settings.This isn't working on wlan1 interface for example, but works on bridge1.
+1It's good S.O.P to regulate the voltage going into your gear, just because the older boards could handle voltage's outside their normal range doesnt mean it is good for them
First affordable dual polarity enclosure I have seen, but 12 dBi is far too low. Thanks for sharing.If they do, a product similar to this http://www.rfelements.com/StationBox-5G ... tenna.html would be decent starting point.
Is this just a guess or have you had problems with a specific grandstream products?And ofc - quality of voip by grandstream is not so good...
DTMF = the dial tones on the phone. "Press 1 to reboot AP1, Press 2 to Reboot AP2" and so on.Nice one, probably.
what is a DTMF Decoder, and how would you like the unit to use it ?
(i could Google, but maybe you have a specific requirement)
Yes, it is called a desulphator. I hear they work pretty good.Has anyone heard of a charger that zap-pulses the battery to reduce sulphate build-up, or somehow detects the level of the electrolyte ?
I think that, with the release of this board, the Mikrotik solution costs about the same, or less, as a Ubiquiti bullet + panel antenna.And your customers what they wanted to be sure they buy the cheapest products Ubiquity.
Nice link. I wonder why they are backordered.Well, i worked out the CCITT CRC-16 polynomial thing with a lot of Google help, but a recent post makes it all redundant now.

It's already been done, and <$100.
That seems like a really bad idea to me.We use 24V panels charging 12V batteries directly across the terminals
New nstreme fixed the unstable latency during low traffic.But maybe this is just an old idea not valid any more with new nstreme?
replace the hub with a switchI used mikrotik on pc-router, connect by hub to lan wired 7 pc, before i'm using mikrotik v 3.28 ping time is 1 ms.. its normal?
I didn't notice the 7 watts line.P=IE so I=P/E 7watts/3.3volts = 2.21ampsHow do you figure?Did anyone else notice, doing the math these things require max 2.1 A. That's way higher than any of the other Mikrotik cards.
I don't think that works properly.It seems to me that if I bridge the lan port to the wlan port and then plug them all into the same switch that it should work.

That page has nothing at all about PPS.The answer (thanks to Ian at Titan Wireless) is at <http://wiki.mikrotik.com/wiki/Firewall/ ... c_examples>.
Then you need to use BGP (distances, priorities, prepends etc.) to control traffic flow.If we have a block of public ip addresses (using public ips for users and don't use NAT) and the connection to other ISPs made by BGP , again this is possible ?
Look closer. It says 777 Mbps with 1500 byte packets.I guess the RB450G wont support that bandwidth, according to the test-april-2009 the board can just support upto 60 Mbps routing
It's very basic.Can you detail it a litle bit RK.
You can attach it to a basic managed switch and use vlans.Thank again for quick reply ,I had RB1000 in my vision but the problem is that RB1000 has only 4 lan ports and i need 5 or more..
Then I will try RB450G but can you recomend me something with more juice..?
Will the loss in speed be seen as lower RX/TX signal strength?we tested this card at +60C, it starts to lose speed when going over +50C. you might want to ventilate the box it's in, or keep it in shade.
Both RB433AH and RB450G have a built in voltage monitor.Nice job Matt. i have been running remote mountain top AP's for 5 years now. One thing that has excaped me is how to monitor the remote AP's battery supply with out a lot of costly equipment. How did you do yours?
Here is what you are looking for: http://wiki.mikrotik.com/wiki/Queue#SFQWhat's TCP congestion algorithm use ROS (over Wireless)?
Any of this or proprietary?
http://en.wikipedia.org/wiki/TCP_conges ... _algorithm
Yes, of course. Why not?i have two mikrotik boards set as APs. one is using v4 so i can connect nanostationm5 clients.
i want to bridge these two using ether 2 on both boards. is this possible.
It has been said that 3.31 IS 3.30 + support for RB750G.3.31 must add some support for the rb750/g.. right? is 3.31 the first release for the rb750/g?
Shouldn't it actually be "max-limit"?Sure. Put a queue tree rule as follows:
Code: Select all
/queue tree add name="ether2" parent=ether2 limit-at=2000000 priority=8 max-limit=0 burst-limit=0 burst-threshold=0 burst-time=0s
Yes. I checked and the expected traffic is showing up in the expected queue but limit-at is being ignored.did u add the passthrough=no on the first 2 mangle rules? Otherwise it will remark everything as "other"
That's one of the combinations I tried yesterday, but it still didn't work.CRAP! I just saw my error. I have the parents wrong (which is why it isn't working for you). Try THIS one.
I already did all the packet marks on my own. Thanks tho.I did not include the full implementation. This is closer to complete.
And you aren't bothered by the 50%, or worse, performance hit but the huge amount of interference?Yes. We do it frequently.
I don't think it's a ducting issue. I think it's a tide/reflection issue in my case, and, yes, it works.You only change the frequency from 5620 to 5660 and that makes enough difference to solve your ducting/over water wierdness issues?
Of course not, that's only 6W!FYI
12V 500mA power supply is not sufficient for RB411AR with ROS 4.3 - it does work (even with disabled miniPCI wlan interface) unless you enable on-board or miniPCI wireless interface
Powered through power jack.
Yes, they do get hot, but they appear to be designed for that.I'm normally running at very low CPU % but still the devices do get very hot.
If you want someone to do all the work for you, you should expect to pay.Hi i have a 450 and 450G
i want to use the ports (interface)1-4 as a switch With port 1 static ip (upload) and port 5 as DHCP Router, with only a 512kbs download and 128 upload traffic, shapping, Thanks in advance.
Did you try any of the XR cards?Hi folks, I have same problem here in Brazil.
A Have a tower under a high hill, with rb433ah. I´ve already tried a lot of card, engenius, ROuterboard R52h, and all the cards survive for a couple days.
So , any Ideias?
Why only mom/pop business?Still, an absolutely awesome home or mom/pop business router for a mere 40 bucks.... you get TONS of capabilities!
Use WDS + RSTP bridge.How can I perform a fast switching from one radio to the other? What mechanism would make this decision to use the secondary pathway?
You have two 5 GHz radios on the same frequency and in the same enclosure?!Running 6 5ghz radios with 2 on the same frequency hasn't posed a problem yet (in 20 vertical feet.)
The method does work - you just need to do it correctly.Unfortunately this method did NOT work. We suffered a network blackout when the new settings were applied, which required a trip up the mountain to fix.
I think it's a brand new product.This case seems nice:
http://www.streakwave.com/mmSWAVE1/Imag ... 20copy.jpg
I think there is a diode to prevent this. But you could remove the diode, at your own risk.
if you plug power into the RB433 via teh dc jack wil there be PoE (out) on the PoE ethernet port?
I strongly disagree. Why would he need directional antennas for ONLY 3 KM?on that distance, forget the omni. buy a RB433 and install 3 sectors directional antennas (pannels)
I use mojiro's cacti template from http://forum.mikrotik.com/viewtopic.php?f=2&t=21189Hello,
Please tell me where do You generate that nice signal graphs?
Really? I have a few in the field and they do seem to be in the 28 dB area.The Pac 28 dB grid I tried seemed to be more like a 20 dB in the real world.
All the small voltage regulators I can find that output 12V or 24V, take only up to 35V as input.You can use a 48-60v Power Supply with a passive PEO, and build your own DC-DC converter to regulate at 12 or 24 volt.
I don't agree with that. I find that even in weak signal situations, turbo is sometimes better than regular. You won't know until you try in each situation."Turbo N" sucks just like "Turbo A" at longer distances unless there is a clean LOS between the two points.
The RB433AH is reporting 19.7 V under light load.how many volts do you end up with at the other end when using the 24v PoE adapter? Test it while it's running ...
RTFM.Just wonder know, What's the language we can use to write the script for the Mikrotik RouterOS...
