this should not be true, all Level4 licenses allow upgrade to v4.xx if they were purchased when v3 was already released. if not, the upgraded key will fix it (when you upgrade to v4beta, it makes a new key, and makes sure that your upgrade times are correct). What about L3 that only show to upgrade...

when is a new version a "new version" if all it's features are backported? the old one becomes the new one, and the new one becomes identical. we could just remove any version numbers, and just tell you when features are introduced. I don't think it's a good idea. Version numbers are ther...

Does anybody tested RB433 (and OS Ver. 3.10) with R52n and 802.11n connection?
no, because 802.11n works only on v4

Is there any plan to add 11n support to v3 in the future?

jsuter

Is there any plan to backport 11n support into RouterOS 3.xx?

Thanks!

My Mikrotik "n" cards are arriving on Monday so I have not actually tested this yet. But I believe you will not see any improvement over 802.11a with this link. You need at least two antennas at each end for mimo (n). Tom MIMO exists to lower effective EVM and other distortions. Technical...

jsuter

such messages have NOTHING in common with 802.11n. You've had absolutely nothing to add to this thread concerning your own performance results. Where are YOUR benchmarks? If you want to control how the content is delivered to you I suggest hiring a consulting firm to type you up a report on how Mik...

I can find a bunch of old complaints about MT UPNP not working with the Xbox - was this situation ever improved?

Can I run/license RouterOS running under a non RouterOS-based Dom0 ('host')?

DomU support is pretty hard to screw up. Mikrotik's Dom0 support seems to be lacking.

jsuter

Well, I decided to order a new mini-pci radio card.
I hope it will work.
Thanks anyway for your reply.

Compex got the antenna connectors backwards on the cards. The 'main' connector has the best performance, but you will need to select antenna B in the software to make it work.

jsuter

I was wondering the maximum density you can achieve using R52 and R52H cards (or any suggestions on 'cleaner' cards for 11a use) at 5 ghz. I'm looking to install 5 5ghz links out of the one RB600-based box, 1x40mhz/nstream PTP, 1x20mhz/nstream PTP, 3x20mhz standard sectoral.

Thanks!

I was wondering if I could actually 'get away' with using the same TX and RX frequencies for two seperate nstream dual 11a/20mhz links with CSMA disabled? (keeping the TX and RX channels a couple hundred MHz apart) Neither link has any chance of the client ends actually ever being able to hear each ...

Alright, I've had a 'rash' of weird issues and they all seem to involve the RB112... It may be software, or power, or maybe capacitor failure. Basically they get very slow - less than 2mbit/sec throughput, extremely long waiting times for the prompt to show up in terminal, takes forever for interfac...

Nothing like answering your own question... This might work for others too... Net result: Disabling ANI fixed my 100% CPU problem. You're right.

After a power blink, I've got even more missing SR9s... I need an answer *now*.

I keep having SR9's disappear after reboots with RB3.x. So far all the systems that have failed have their SR9 interfaces attached to a bridge, but I have very few 3.x upgraded boxes in non-bridged situations, running SR9s. I've witnessed this from 3.0 to 3.3. All affected units have been 100-series...

Crap -forgot to update this thread after our tower climb.

when did the ethernet stop working? Sounds like a hardware problem. The ethernet quit when I upgraded routerboot on the unit.

I upgraded routerboot last night on a ~6 month old RB112 which seems to have broken its ability to connect to Ethernet. Is there a way around this problem?

I need routerboot images for the following machines:

* RB112
* RB133
* RB133C

Because I have a LOT of Mikrotik's mistakes to clean up...

jsuter

Figured it out... apparently the RB133, cat5, PSU or something is coming up short for power. Reducing the maximum txpower of the XR2 to "14" (from default) appears to have fixed the problem for now.

jsuter

RB133, 1xSR9, 1xXR2, 24V/1A PoE. SR9 in STA WDS bridged with the XR2. XR2 has one WDS peer and and 3 regular clients. RSTP is enabled. WDS peer has the same basic situation except no SR9 feeding it, just repeating off its 2.4 radio. One SSID is identical between the radios, the other SSID is differe...

jsuter

Another issue - I'm seeing duplicate packets on the affected WDS clients *including* those in 'Station WDS' mode (they just happen to be more stable than AP+WDS connections). approximately every-other ping has a duplicate response. Any help would be appreciated.

jsuter

I'm seeing a consistant problem across our network concerning AP+WDS mode - essentially we see random disassociations without good reason (either 'no beacons' or 'sent deauth'). In both cases the RF situation is fine, and in a couple circumstances I was able to remove Mikrotik's software (ie - repla...

jsuter

Tried another radio?

Not yet, but it will have to occur in the next few days as I'm getting tired of dealing with the problem. We'll end up replacing the unit with an RB133 with a new sr9 and 8602 thats been properly tested as assembled.

Upgrade to version 2.9.45 and it should get well. Unluckily that didn't help at all... Still requiring manual disable/enable cycles anywhere from every few hours to every few days...

I keep having an incident, irregularly, where I have an SR9 start showing an unrealistically low noise floor (-122ish) and all the clients drop off.

Hey Steve shoot me an email at support@ubnt.com THanks, Mike I'd really like to know more about problems this issue actually causes.

I've noticed an issue across all my MT-based towers... If I disable 36, 48 and 54mbit rates I get considerably more stable connections.

So my reply last night didn't make a whole lot of sense... I'll attempt to explain better...

Theres no fl...

Well, that'd be an IP queue. I need to set an interface queue to keep. With my old cisco, the choices are basically fifo (pfifo), red, and fair-queue (sfq). On the Cisco, setting the interface to fifo ("no fair-queue"/"no random-early-detection") will give me the same performance...

Hmm, then the queue settings did not make any changes to the ping (56 byte) times when uploading (1500 byte packets, at full line rate) over the connection... Very weird. I'll investigate more in the morning (2AM here)

Have the users tried adjusting ack timeout using 'athctrl -d [distance in meters]' yet?
