what were your findings?

We currently have about 500 subscribers using Mikrotik gear, and I sometimes wonder how our business will continue to compete with speeds of DSL constantly improving. In our town, your can get an 15Mbit connection for less than $40/mo. For the same price, we offer only 1.5Mbit, plus we have substant...

Hello all, Has anyone had any problems connecting a PS3 to a routerboard? in my case, I have a RB230 with ROS 3.10 With encryption, I am unable to connect. The logs fill with "data from unknown device, sent deauth" I have tried all configurations avail in yellow dog 6, and a number of secu...

alright, set the rates to 24/36 only. I never messed with these, because everyone always shouts "Leave at default!" I was usually at 54 with an occasional drop to 48. For the most part it seemed consistant. But I have to say, ping times are better, stability has improved (still not perfect...

dual nstreme is a performer, But it is not without it's faults. The concept, and implementation is fairly simply. However, my nstreme2 setup has problems, and I have been working with support to try and figure it out. First off, nothing in the price range of a dual nstreme setup compares. I have a p...

DesertTek

Can you point us in a direction to do such a thing, or provide us with an example config. I currently am running nstreme2, and at least twice a day I drop connection and the watchdog reboots. Support suggest a bad pci port, but in any case, we need better reliability. if not post, please send to gcs...

I have noticed the 100% CPU utilization on RB133c clients. If you load only the packages that you need the utilization seems to get better. The routerboards will get sluggish and stop responding to commands. A reboot will take care of the problem for a while. Does anyone else find this ridiculous? ...

we noticed that we could barely log in remotely using winbox. took up to a minute to login. Once in, screens were very slow to update. Opening New Terminal took about 10 seconds as well. Could this be an incompatable configuration from 2.9.5x? Or is the 230 simple antiquated and a poor choice for a ...

What is so different about 3.0? New features, poor coding? We upgraded three RB230s. after seeing the terrible resul...

If all your post are like the one above. Well, you know what you are.

There's nothing worse that a forum member always saying READ THE MANUAL DUDE! Cmon. This is supposed to be a community for help, not an elitist club. A more appropriate (and appreciated) response might be... "This is too vague a question and would require a detailed and all inclusive answer. Pe...

this link has been running surprisingly smooth. While I was hoping for a better TCP FD bandwidth, I am finding that since bandwidth consumption is about 70% down and 30% up, that the RB333s are doing just fine in the DS3 backhaul role. I have been graphing the CPU, and we average around 30%. So I am...

Hey Scott,

Sorry, was still editing when you posted. To answer your question... I feel this link should be better, but I have run out of ideas on how to make improvements, especially as it relates to framing policy. Maybe it's good and I'm just expecting too much.

Hello all, My first post was about what is needed to setup a real backhaul for a DS3. This post was started once I was convinced my hardware setup should be good enough thanks to all your input. Summary: nstreme 2 on a 3mile link using 2 rb333, 4 R52, 4 29dbi solid dish, 4ft Andrews LMR400 nmale pat...

DesertTek

Thanks for all the activity fellas. I think I have my question answered for the topic head. Some seem to think with a properly configured setup with this hardware, I should be able to get around 35mbit FD. If I want more, most are saying go with an x86 setup. OK. I am going to start a new thread cal...

Disabling HT in BIOS works!

DesertTek

We had the same exact problem. And we duplicated it several times on seperate CF and iso installs. We have 3 powerrouter732. They run an Intel SBC8a820 mainboard with pentium 4 3000 HT, 512GB DDR2, standard 64MB flash. Definately a problem with 3.4, HT, and compact flash. So, question is, where can ...

DesertTek

We are in the same situation. We have tried various settings, but fail to notice any difference running bw tests. best fit, exact-size.. what size?. Anyone have suggestions or can refer to related literature?

DesertTek

jp, At first I scowled at your suggestion, but in looking more open-mindedly, you may have a valid point. Being a business person, fussing and fussing with a product is just a bad idea. I looked at the Trango 45mbps and they are on sale this week only, helf price. Crazy. But of course, this item doe...

DesertTek

thanks for the replies. What I am really after here is full duplex, low latency, and stability for the youtubers and gamers. This is going to be a busy link. I will try to simplify the settings again, and see what that produces. I never mess with the power, and on nstreme2, there are no default rate...

DesertTek

hi guys, been working with settings today, not really sure what certain parameters should be. But anyways, my current numbers for signal strength are: site 1: -60, -62 Site 2: -58, -60 This is at 48Mbps on the cards, as having the data rate of 54 produced erratic pings and speeds. regarding the nois...

DesertTek

hello, individually, the links show a CCQ of 100%. In fact, we get near the same performance on a single link as we do both when nstreme is running. I will grab some snapshots today. I do HOPE it is a problem with configuration, as the hardware seems to be good. All cables tested, 2ft solid dishes, ...

Hi, we completed a nstreme2 configuration last week. 4 mile link, -53/-60, 42SNR, -90 noise floor. boards are rb333. cards are r52h. using 29dbi solid dishes. Freqs are 5210/5610 HPOL/VPOL. At first, test looked good... on UDP. But try as we might, even with turbo enabled, we cannot sustain more tha...

same here forepoint. I would love to see this config. Thanks for your contributions to the community! I wish more were as generous. gcs85 at hotmail dot com

cool, thanks for sharing. What do you ping times look from the perimeter of coverage?

DesertTek

If you are running firewall rules, queues, hotspot or full 54, I wouldn't expect more than 20, especially simultaneous at 256. I know you said to ignore the the limitations of the 133, but then why bring them into the equation? We have tried this scenario many times with RB112s (same proc and mem) w...

If you are not running anything too complex on the APs, I would say upgrade the APs to 3.3. We noticed good results. However, we have seen the bridges on a few 2.9 ->3.x upgrades go a little wierd, and had to be recreated. We also think 3.x on 175Mhz procs (112/133C) doesn't seem to hold well. But o...

DesertTek

Hi, Here are some suggestions: First off, upgrade your AP to 3.3, then upgrade all your clients to the same version. We have found best results with clients on 175Mhz procs to run on 2.9.50, with APs (266Mhz or better) on 3.3. After the update, do a NEW TERMINAL on each client, then do a sys rout up...

Very Cool. We are trying it out now in our lab.

We had GREAT success with this upgrade. We are always leary to upgrade more populated sectors that may be located in hard to get areas, but everything went great. Wireless performance improves noticably. Ping times DROPPED. We upgraded two RB 230, 5 532A and 4 RB333 and not one devasting problem. Ho...

Heya Expunge! So, in reading this post, I have to concur with a few things. First, 5.8 is the way to go if you have LOS. We too have a saturated field in 2.4, so we just don't mess with it for backhauls. We use 5.6-5.8 for long hauls, and 5.1-5.3 for short hauls. Second. I personally love amps. I fi...

Hi. We buy Eagle Plastic Devices part number 561-187TAB from Mouser electronics: https://www.mouser.com/catalog/633/1750.PDF If you buy qty, you can get it for about 1/4 the advertised price from elsewhere, plus NO drilling.

3) if you're worried about redundancy, do not use NStream 2, setup 2 individual NStream links, with OSPF and configure them for full duplex routing by manipulating the interface costs, that way if one link does drop, it will nearly instantly fall back to half duplex communication on the remaining l...

DesertTek

That is odd. Do you have the reset jumper on? Have you tried upgrading via a web page at the url of the MT?. There is an option to upload and upgrade there.

DesertTek

I have to agree. The RB230 is one of my favorite routerboards due to its versitility and reliability. We have had four in operation for more than three years now. Only had to replace one due to lightning damage. And yes, we boot to CF on all of them.

DesertTek

bump. The real question is how do wisp operators tune their services to come close to matching DSL/CABLE competitors? Are we all in a dying field whose only hope is to service non-service areas?

DesertTek

first, is your license current?

second, are you using the correct version? (rb100 series)

lastly, try dragging and dropping the npk file from your desktop to the file section of the winbox session on the board you are upgrading. Wait until the size reports correct, then reboot.

DesertTek

Hello. You have definately identified what I would deduce is your major problem: Not enough voltage! Years ago we set up RB230s with 3 200mw cards on 12V PVAs. We experienced almost the same exact problem. Our solution was to upgrade to a 24 volt system and we have been running for years now with no...

Did you mean to say S400 cable? As in firewire cable? Maybe I am unfamiliar with S400, but we use LMR400 cable at up to 70ft runs on our towers to 5gHz antennas with no problems. However, we do use premium Times Microwave cable, so loss is minimal. Regarding your question abour 2.4 to 5Ghz cable, we...

Assuming you are using seperate channels for each sector, this may be a difficult task to accomplish. Your omni is likely to be the sector that suffers the most (what will you be using that for?) Make that your most distant channel, say 11. Try to have good physical seperation between antennas (6ft ...

DesertTek

We typically aim for a SNR of 25 or better, a CCQ (fluctuations accounted for) of not less than 70%, and a radio signal strength of -79 or lower. Any worse than this we consider a stronger card, different antenna, elevated mount, etc. BTW, my installers have to be constantly reminded to create a cle...
