yeah as i said this is not that practical to save the 200$ to buy a bigger antenna..it's probably the electricity usage for a couple of days.... but man if you get down to 1k you have a 300 fold increase in sensitivity i suppose you could stack up 20 or so peltier elements and burn 50kw to do it.......

ctech4285

i did some wiking specifically: http://en.wikipedia.org/wiki/Johnson%E2%80%93Nyquist_noise the thermal noise floor for 20mhz wide channel with 50ohms is -101dbm, and that happen to be very close to what the R52nh card reports most of the time. -174dbm is there thermal part at 300kelvin if one where ...

ctech4285

first I am not getting lower than 70dB readings, although links are formed upto 100m. My main goal is to push the RSSI levels to below 70 (on laptop) and below 75 (on AP) i think you want to push them above -70dbm they are negative numbers, unless you some special RB Card that i don't know about you...

ctech4285

yeah i did that, but nothing will uninstall, i think ROS needs disk space to do it..
no error message nothing, after reboot nothing changed

ctech4285

is there a way to free up some space on an RB433 (ROS 5beta6) whit 0bytes free without physical access? i installed dude on an rb433 with 5mb left over space over time the data source filled up all the remaining space.... i tried removing the data sources from the client app but it does not look lik...

ctech4285

is there any reading material/books on this specific topic? i would like to do a link some times

ctech4285

they are on .11g cards too and i don't think mimo is not part of .11g

ctech4285

what does the radio do with two antennas, does it add the signal on two antennas? or does it have two modem chains for each antenna? can i connect two directional and point them in different directions? or does it subtract the signal from each other in order to filter out near by interference?

ctech4285

oh one more thing, will the impedance change if you connect two antennas together??

ctech4285

are you talking about the return reflection on an antenna causing a standing wave in the coax cable that propagates back out of the antennas, and if theirs resonance this signal will grow endlessly? could you not connect a second radio card via splitter (or better yet just point an antenna right at ...

ctech4285

but the recieve gain is +3dbi minus some losses. and since an antenna works as sender and reciver equal it has to give a gain sending unless my premis is wrong. the beem width has to decrease i think.

there is an error in you logig

ctech4285

reset the interface
set band to n only and click enable interface
there you go

ctech4285

would it be possible to gain 3dbi if you connect two directional antennas together for a link? is there anything to watch out for?

ctech4285

the disk was completely full on the RB i think that might have been the problem.
i am using a new board since the other one got hit by lighting a strike
its working now

ctech4285

the rb433 was running the latest version of the dude as of a few days ago. and i am using 4.0beta2 as client

ctech4285

hmm... i found something thats a little closer, but nothing that looks like bps iflnoctets 1.3.6.1.2.1.2.2.1.10.1 "The total number of octets received on the interface, including framing characters. Discontinuities in the value of this counter can occur at re-initialization of the management sy...

so i got some probe with raw value keep=very long time, and created a chart for it. but every time i open the chart it begins displaying at the time i open it. but i want to see how it was a very long time ago... this probably sounds like a newbie question well it is...lol dude server is running on ...

ctech4285

ok i figured out how to do package count on an ethernet interface. how to i convert that to b/s-1 units?

i am looking for some general advice, god i mean google is not very helpful if you have no clue what your doing...

ctech4285

i am new too this. but is there an easy way to find out what service does what?

specifically i need to monitor tx/rx bandwidth on ether1 on an rb433. i found an example on how to do it on a wlan interface, but not on a ether interface...

kind regards

ctech4285

sweet thank you

ctech4285

i get login failure, using the same usr/psw then winbox
do i need to do anything special on the rb to allow remote connection on that port?

ctech4285

ok i installed dude on the RB, but where do i find the config options????

ctech4285

i want to do the same, install dude on micro sd on rb433ah
anyone?

ctech4285

ah perfect thank you

ctech4285

i need to test if a route is up via ping without actually using it for routing traffic. ping interface=wlan2 google.com or so is not enough, i need to check the whole route.... you can do ping routing-table=blah google.com, but have no idea how to create these table. googleing did not turn up anythi...

ctech4285

very intresting... if there are no other reasons why this stuff is so expensive then we should see it coming into mikrotik range in a year or so..i read somewhere that there is a reference design for a wimax card for under 100$ i am wondering if we just gonna need drivers and OS support for wimax or...

ctech4285

ah interesting, when there are performing mini pci cards, then you will support it?
according 'press releases' its being deployed in almost every country

ctech4285

whats the timetable for wimax on routerboard?

ctech4285

i love mikrotik too, but you guys don't make everything.

ctech4285

problem solved...
the thing wanted a dhcp lease but radius would not allow, because the mac address was not listed, so i set up a different dhcp server and then the device showed up in the arp list...

ctech4285

nob no arp entry

ctech4285

i need to know the mac of a device thats connected to ether2. the setup is on top of a 15m bamboo so i really don't want to go up there to find out. is there an easy way to find out? rb433 with routeros 4.5

ctech4285

that above mailing list is referring to a document more than 10 years old. at least find a newer copy of the license, duh

oops sorry

ctech4285

Did you read the GPL part of there license?

does that mean they are complying?

according to some this is not enough to be compliant

i really don't know enough about this to have an opinion

ctech4285

Every router comes with a copy of the license.

a copy of a license and being gpl compliant are two different things.

Honestly I do not think there is another product out there that compares to MikroikOS. Its amazing what it can all do.

YES it is awesome but it can be better!

ctech4285

ok closed source thats Mikrotik right if the GPL violations allegations here http://lists.gpl-violations.org/pipermail/legal/2009-December/001759.html are not true i don't like it and the arguments by them are rubbish in my opinion there is a RB433 in my collection that does not run stable should i ...

ctech4285

1. Most of the important stuff is written by mikrotik (some routing programs, drivers, wireless part) and is not open source. ok how about bash access then? 2. If you start adding random stuff to RouterOS, we can no longer vouch for stability, compatibility etc. Just use linux then. according to yo...

ctech4285

I mean, packet routing facility - whole subsystem, not only routing protocols

there got to be a way to have the best of both worlds RouterOS and Linux

what is MK business model selling licenses or selling hardware?

ctech4285

et me guess... because routing core is proprietary, and RouterOS without routing is not RouterOS? =)

but i could install BATMAN witch is more then nothing
MK routing package could be installed with a license and everything else is there for people to play with

ctech4285

Router os is Linux, but why proprietary userspace management applications. then no patches no source code nothing? why not provide code and a wiki on how to build RouterOS and leave out all the proprietary package. why if MikroTik only sells routeros with the routerboards they would worry about lice...

ctech4285

is it possible to add a virtual wireless interface in virtual openwrt?

ctech4285

i would like to get an om1p open-mesh router to use a MK 433 as gateway

ctech4285

the chipset is atheros on both the mikrotik ap, and the dd-wrt repeater
it got a lot better without doing anything, signal/noise stayed the same less then 1% package drooped, bt ping time is still all over the place from 7ms >1000ms and avg 200ms

ctech4285

ok i got an access point, and a repeater an om1p running dd-wrt and i get crappy ping result even with 30db signal to noise and it is between the repeater and the ap (rb433). laptop to the ap does not have any problems ping avg is <6ms but dhcp-server response takes forever. i did a reset of the int...

ctech4285

i turned off encryption and management-protection, now everything is perfect even with sometimes low signal strength of -85db 0% package lose as to before 40% package lose with encryption and management-protection

ctech4285

mikrotik can you give us some more detail on how to verify why management-protection failure happens?
i am trying to figure out why my 1km link is so crappy, frequent disconnects at certain times and its perfect at other times.

ctech4285

i see a lot of wds disconnects sometimes i get management-protection failure is that a sure sing that someone is trying the disconnect hack? its not in this log but i should not have disconects this often, signal is usually around -70db or better. 17:41:08 wireless,info 00:0B:6B:DE:A3:D3@mesh: disco...

i am providing wifi in matiguas nicaragua this is a pretty poor place and quality of service is not so important, if a client has to wait 5 minutes for page to load thats fine

so i guess changing the qos buckets time out would be the way to go but h

ctech4285
