Contemplating on this subject - wouldn't it be a nice idea for MT or someone outside to create a script, that runs over all public ip's and builds a list of vulnerable MT routers (or get that list from those cocky "investigators" that are publishing stories about Mikrotik), then a second s...

If you haven't yet found an answer, then I could chip in - for this size of devices wind loading calculation should not be calculated by european civil engineering code, as it will be negligible. Even though, we are able to make approximate assumptions. : If you look here, you can find rather precis...

We could introduce custom / multiple DNS name as some sort of premium feature maybe. Well, that could be feasible, because this dns as it is, is useless. Would you remember your router dns name if ir was 42711237ace5.sn.mynetname.net? Thought so - you wouldn't. Using strange script to manage Dyndns...

Why does no one use the UPS company MeanWell? This solution is very effective. This solution has the ability to remotely control UPS. People like to overpay for things and support crazy manufacturers like APC. Myself, I bought some 27V Meanwells with big batteries and the script does it all for som...

* Very bad latency (>7ms) You should consider fiber if 7ms is high. current software version: 2.38 This is routerboot version - software is 5.xx I would expect >100Mbp/s Definately depends on many factors, but don't hope for huge numbers. * When I begin to sustain traffic to a downstream host, late...

Just my 2 cents in here: 1. lower the transmit power until you are in mid-50 rx/tx (-55-60db) 2. in HT MCS tab on AP, leave only one mcs in both Supported and Basic MCS (try to avoid MCS 13-15 if you are in noisy environment) http://www.dbii.com/wiki/index.php?title=F52N-PRO#Example_.22N.22_setup_us...

But, why would you choose rb800 over an intel Atom platform - namely D2500CC? It has 2 real cpu cores, 2 Intel gig lans, and ofcourse you can boot OpenWRT or DD-WRT, although I would recommend Openwrt. Even more - you can get the hang of Routeros rather fast and things that you can do in routeros ar...

janisbvp

Well, sampling is definately for vendors, like Mikrotik - early bird catches the worm, you know.
Othervise we would have to wait longer.
Anyway, I am not sure, this will bring revolution with our strict European frequency plans, but we shall see in the future.

Missed this one - thank you, MartinEmrich!

janisbvp

Well, that seems to be the reason.
Honestly, Openvpn as it is in Routeros is by 90% useless.
For the owners of RB450 there is an answer - Openwrt, but for the roadwarrior scenario I hope to see Openwrt on RB750.
I have migrated to x86 with openwrt for just that reason.

janisbvp

And, more than that, I would like to see a single chips solution (Atheros wlan+Quallcom dualcore) - then we add justa bit of components, stuff it in a small round housing with antenna and stick on a dish - that is a reasonable evolution of groove.
Ups, I am dreaming in the middle of working day!!!

janisbvp

Yes, first step is still in process, Atheros has no chip yet.

Well, not entirely true, but close to that:

There are other 11ac features we like to have. E.g. 256qam. Not a bad modulation, though in a crowded 2.4/5Ghz spectrum... we struggle to work with 64qam. But, I guess it is worth waiting for, just to see. Scenario is simple - Atheros gets licence and makes a chip, gives specs to Mikrotik, and in a...

janisbvp

Well, if you do read 802.11ac specifications, you will find that it is as clean to the spectrum as a space shuttle - 80Mhz. Even now, we have polluted enviroment - do we need more pollution? I hope, noone allows the use of these devices outdoors... ever... Also, Buffalo is a company, that creates IT...

janisbvp

As I said before - you should find out the 'unreliable' link and point it out. If you would check the power consumption of the devices you can safely assume, they are not the case of problems. As I said before - try to get rid of power fluctuations under load and you will get stable system. At least...

janisbvp

At the moment I am thinking of CAT6 and higher voltage (48-60v dc) anyway. As the insulation between colours in cat6 is much better, for near-100m runs it would make a great poe carrier. And the voltage converter for 48>24v would be rather easy. Of course, nothing beats dedicated cable and full volt...

janisbvp

Yep, probably right - the diode was just for reverse-polarity protection anyway.

janisbvp

Still interested in what the basis of using an OmnitikUP rather than a 750UP might have to do with any of this? I think none, but MT staff will correct me if I am wrong. Think about this thing though - power consumption of routerboard "example1" is 0.2A at 24Volts, so at 12Volts it could ...

Little ram. 1GB would be around and very good

-------stripped-------- I just ordered some 4:1 DC power splitter cables and was planning on just putting some POE inserters and bypass the 750UP for the purposes of the power which gives up the ability to remote power cycle etc. (and basically turns it back into a non POE router, which was working...

janisbvp

RB750UP doesn't really have an outdoor enclosure - you should be using it inside a tough enclosure, together with some other devices. Also consider the OmniTIK UPA, which is an outdoor wireless device. Well, no one has put it outdoors - we do have a good and spacy outdoor enclosure with good heat d...

janisbvp

if you are powering other devices - that is the temperature.

Would this mean, that RB750UP is not meant for what it is meant - powering 2,3 or 4 routerboards in tower? What is the reason to pay the difference for 'UP'?

janisbvp

Not exactly. The heating and power supply is not the exact problems - power supply of rb750up looks solind and rather heavy, so there should be no problems. Tested it with a resistor @ 2amps and it works perfect with almost no ripple. The problem on tower is that you have long cable runs with a rath...

janisbvp

From what I have found out, most of these problems come from being economical on psu circuits of routerboards. My current setup: ====>RB711-5hn-m (uplink) / PSU 24v/3A >===92m cat5e outdoor cable===>RB750UP - =====>RB711-5ufl (sector) Just could not get it to work with 24v psu. With 36v psu, RB750UP...

janisbvp

You can probably raise the voltage on input to some 25-27 volts if you can. That should overcome voltage drop in cable. Known fact is that routerboards have a little current spike on connecting power and the they consume next to nothing. Bad thing is that 25-27 volt supplies are not a common thing i...

RB751G and RB751U now have extended MMCX connector, so no special antenna is needed. ...and I thought that an antenna with mmcx connector should be considered "special"... Most of antennas are rp-sma.. Well, I guess, rb751 internal antennas are enough if it wasn't for rather odd config po...

http://www.hark.com/clips/fjppvkfnzr-i-been-saying-it
I think it shares my thoughts on this matter.
Just a single daemon, compiled from a ready-made source and integrated in ROs would have saved us from this thread.

janisbvp

No, it doesnt.
When I test with a deliberant APC 2Mi I pull easily 70MBit on a simple http speedtest.
This is with the same notebook, in the same spectrum and at the same distance.

Well, should I carry AP glued to my laptop? Not the reason I bought it rather slim and good-looking.

janisbvp

Well, just my 2 cents - I did try 751 and the performance solely depends on the card that is in the pc and clean spectrum. My HP Probook with Broadcom N card works waaaaay better with old wrt54gl than new 751 and the signal strenght of 751 antennas is something to talk about as well. Right now I hav...

I would propose a clean workaround in one of 2 ways: 1. Create an update daemon for ROS (sources are out there - use ready made inadyn or whatever) and stop this script menace for once. 2. For security reasons, create a dns service for MT clients, so we don't use dyndns, although, I think dyndns is ...

This is the reason, why i didn't replace my tp-link 1043 with rb751.

Also, 24v ups, on 2x12ah batteries can keep your system up until you have free time to solve that situation, but 400VA 220...

janisbvp

Well, taking into account, it is only an Atom cpu, and total routing capacity will not reach 1gbit, we might connect internal nic to 5 or 8 port VLAN switch and move on.
I wonder if RB250GS would fit that use?

janisbvp

google "MikroBits Ainos 2071"

Totally different ballpark, with c2duo cpu, 60w idle consumption, but not a bad idea aswell.
Alternative to rb110 has to be power efficient - so Intel Atom makes sense.

Some friends brought to my attention this baby from SuperMicro:

A piece of idea - RB411RN - 2.4Ghz N-lite
