Is anyone still using X86 bare metal on ROSv6? Seen the weird trick to get x64 support with higher memory support over 2GB (v6.31). Thinking of deploying a new edge router based off bare metal. We prefer the more stable v6 over the v7 and also need BGP convergence time to be as low as possible.

I ended up giving up on this project.

kblazk

Well at least we are getting somewhere. Maybe there is a problem when 2 of MT designed cards are connected on the same backplane. Interesting that a Ubiquity mixed with an MT does not give issues. That is the first comment I have heard so far relating to mixed manufacturers on same backplane. But I...

Side by side comparision. I didn't have a RB600 laying around at the moment so i just put two RB433/333 beside each other and did the test again. Bleed over was almost completely gone. Very minimal bleed over at 25db power. If i dropped back to 20db power it was gone compleatly.

kblazk

Now this is 10mhz channels. Now we are able to put two cards on top of each other with full power and not bleed over too much. You could run 3 non overlapping channels at full power 25db or use all 5 if you are running a lower power setting such as 15db.

kblazk

Tests below are all 20mhz channels with different power settings. at full power 25db you could only run two cards if they were on on channels 5745 and 5825 and you woud "get by." Even then they are still seeing each other at -93 on the edges.

kblazk

check the following images - test done with one card transmitting into a dummy load and spectrum analyzer hooked up to the antenna port on the stacked card that is not transmitting.

kblazk

I have a spectrum analyzer. I will be hooking it up to the antenna port on a stacked card in a RB433 to see what is visible between the two cards. I will upload pictures. I tested this once before and I can confirm there was significant bleed over.

Got two RB433AH's on the bench. CM9 in each. Simple bridge with WDS setup as per the wiki. Doing a 5ghz-Turbo mode I can get about 52.1mbps UPD flat line all day long Doing a 5ghz-Turbo mode I can get about 42.6mbps TCP flat line all day long if i enable N-Stream with bestfit/3200 I loose throughput...

i've opened a Ticket #2009061066000474 on this issue

kblazk

I see this also,

The problem is not with the Dude v3.4, this problem is on the RouterOS end. Was running fine with ROS v3.15 on all the devices. As soon as we upgrade that device to ROS v3.24 we loose our bitrate's.

kblazk

is this MT/TRANZEO disconnect issue still resolved in 3.23?

I'm so scared of that and all the nightmares it caused it is keeping me from upgrading my network

kblazk

I've got 3 RB433AH's that are all doing the same thing. Wondering if i might be doing something wrong. They came with 3.23 but I'm trying trying to go back to 3.15. I formated and ran netinstall and installed the "routeros-mipsbe-3.15.npk" package. It appeared to be successful. It prompted...

kblazk

Here is my network diagram right now. As of right now the PURPLE 900mhz AP's are not there but this is so you can get the idea of what I want to do. Basically I already have a 5ghz infastructure I just want to add the 900mhz for roaming and utilize my backbone already.

kblazk

when the client roams from AP1 to AP2 the traffic should transfer over to the backhaul on AP2?

this is correct

kblazk

thanks, does this include how it get the AP'S to push the bandwidth across the backhauls rather than going through the WDS ap's for traffic? Will each AP have it's own backhaul? For example AP1 and AP2 each have their own wired internet connection and when the client roams from AP1 to AP2 the traff...

kblazk

1. You'll either need to setup static or dynamic WDS links between the APs. 2. No the clients do not need to be Mikrotik. 3. You will need to put the WDS and WLAN interfaces in an RTSP or HWMP+ bridge. Read about RTSP http://en.wikipedia.org/wiki/Spanning_tree_protocol and HWMP+ http://wiki.mikroti...

kblazk

Its getting to the point if i can't find out how to do this that I'm going to have to go with the Alvarion mobile 900mhz since it already does the hand-offs between AP's seemlessly.

kblazk

i watched the video, that is exactly what several of my AP's are doing, all Tranzeo clients dropping. Some of them only do it a few times a day but i had one AP that was doing it every few minutes and i had to replace that AP with Star-OS or risk loosing all those customers. Why is Mikrotik being so...

kblazk

Ok i found my problem, one of the backhauls had a bad card. It was a senao 8602, had terrible ccq on every channel. Replaced with a CM9 and now i can get 24mbps UDP through from both ends of my network. I turned NSTREAM on for the first time ever and WOW! :shock: 37mbps UDP from one end to the other...

kblazk

I currently have a fully routed network and my 5ghz backbone links are setup as follows. 1. AP's are setup in mode "AP-bridge" 2. Clients are setup in mode "station" 3. SBC's are RB333's RB433's, and RB600's. 3. Cards are all R52/H's, WLM54AG's. I'm not using anthing else just ve...

kblazk

Ok, let me start off by saying what I don't want to do. I am not interested in seting up a mesh were one would install single radio hotspots all over the place and roam using the single radio for backhaul and AP. This is what everyone else is doing on the forms and my scenario is quite different in ...

kblazk

whats the point in adding new features to something that you can't even use in the first place????

kblazk

well unfortunately I tested the RB600 with 24v and 48v and it made absolutely no difference from 12v.

kblazk

I will check it on one of my sites here in a few days and report back what I find. I am in communication with another WISP that is not experiencing these problems and they are all using 24v on their towers and my only towers that are having these problems are run by 12v setup's. I have 1 tower that ...

kblazk

ok I'm on to another hunch here, i wonder if this problem is related to power and voltage? does 12v versus 24v make any difference for anyone? Reason I ask is because someone stated in another post that once they hit a certain number of clients that they had to use a higher voltage power supply or t...

kblazk

Well I don't think that's it either now, I took the poor signal clients out of the access list and it would still drop everyone off every 5 minutes. I seem to have isolated this problem not to noise but to large amounts of traffic. I can trigger the re-connects by doing BW tests from one of the clie...

kblazk

After reading this again, I have a similar problem. Seems to be corrected by getting the signal in at the AP a bit closer together. My target is to have all signals from -70 to -80. Any time I have a CPE Tx to the AP at worse than -83 or so, all radios drop off randomly. Changed out the CPE, got th...

kblazk

someone said in one of the wireless lists that they talked to MT and were told that they (MT) is going to get the 802.11n support added to their software and THEN start working on this problem.

kblazk

is this a problem that can be solved be removing all PRISM clients from the AP because at this point I am willing to invest in replacing the old CB3's and CPE-200's

kblazk

I am having this problem on SEVERAL towers. For no reason at all the interface will decide to dumb all of my Atheros clients. and then within 2 seconds they will all connect back up again. You can tell that it happened because the "uptimes" are so short. Funny thing is that the 1 lone pris...

I have a simple setup now with a RB153 board as a simple NAT router with 4 bridged ports for lan and 1 port for WAN. I want to limit port 5 to 768k/128k for WAN traffic but still allow its local LAN traffic unlimited. So far the best i can do is set the 768k/128k for port 5 and that works but my loc...

kblazk

ok i found what i needed, problem was i was using prism cards and apparently ony atheros cars will do this. I accomplished it by setting the backhauls in AP-BRIDGE mode with the same SSID and channel and then turning WDS on dynamic mesh.

kblazk

Is it possible to setup a backhaul using mesh? Searched forms all day and found nothing.What I want to do is have 4-5 sites with omnis backhauling on 5ghz in a mesh for self healing.

:if ( ([/int wireless monitor wlan-station as-value]->"status") != "connected-to-ess" ) do={ /ip dhcp-client release wlan-station } the above script does not seem to do anything. I am running this on a mobile client with a connect list, I need the dhcp to release when it chooses ...

kblazk

Where on earth do i put the scripts at that i find on here???, i have found 2 scripts and i don't have a clue where to put them, i put them in the System > script, that didn't work, then I tried the System > Scheduler, that didn't work, do i have to put half a script in the scheduler and the other h...

kblazk

how do i use this script, this is exactly what i need but it is not doing anything

kblazk

this is exactly what I need but where do i put the above code to do it? I can't seem to get scripts to run, never done one before. My DHCP is not renewing.

Ok i just got back in, i was looking ont he board and there was a jumper that was open, it was labelled soft reset. With the device off I put the jumper in the closed position, then powered on. Then after a min or two I powered it off and put the jumper back open Powered back on and it was reset, MI...

Just got a new rb133 out of the box and was in the main screen and i accidentally clicked disable for the ethernet and now i am locked out. Is there any way to save it? I had no wireless card in it and its a 1 port ethernet. should i throw it? send it back to wisp router?

I will be needing to supply a 100Mb pipe over 20 miles to support the broadcast of 4 HDTV channles. I already plan on using 32db dishes but will mikrotik handle this and will the WAR4 boards work or do I need to use PC's? Radio's will be mounted at the bottom of the towers. What do I need in Mikroti...

I would like to use a RB153 as an AP with 3 senao 2511 running 120 sectors. I will probably have about 15 clients per card with total throughput around 1.5mbps. I have noticed a lot of people saying the boards reboot a lot and am a little weary of implementing this. Is there a hardware issue with th...

Here I made a topo map and here is my routing tables off of this router that is causing me problems, In the drawings I can not ping from DSGE, BTT, or NOC towers to anything from the CST tower or farther back, but in the CST tower and back i can ping everywhere on my network. And the internet works ...

kblazk

Well here is what is going on, I have this router in place all it is doing is routing, it is not functioning as a wireless device at all. The routes are all showing up as they should, internet traffic is going fine but i can get traffic to flow backwards, example, i can't log into my AP or BACKHAULS...

kblazk

My RIP tables seem to be updating but i am having some problems. I read the manual and it says that under "IP ROUTES" that the routes should show up with a distance of 120 but under mine the routes are there but for distance it says nothing, I was wondering if this is part of why I am havi...

kblazk

Ok now i understand. I am willing to bet there is no way to do this in current MT.

Brian

your probably right

kblazk

Ok, I am confused. Your asking if you can queue traffic to and from your MT. The answer is yes. How do you do it? You use queueing. You use queueing just the same as if you were trying to queue anything else. The only difference is you will only be able to work off the 1 interface, since we are tal...

i'm running a wisp, and since there is an AP involved why not get the data to the client with fewer packets = less collisions as opposed to more packets= more collisions???

kblazk

anyone?

is there anyway i can queue download/upload traffic of the web proxy based on which of my internal ip addresses requested it?

i was at first, then i switched to 1492, didn't help either, then i started a transparent proxy and it all works now with the proxy
