I changed the mangle rules and NV2 settings to the settings below. These are the only parameters that I've set. Anyone who's had success with NV2 QoS, please let me know if you would do anything differently or if I've left anything out. Thank you. /ip firewall mangle add action=set-priority chain=ou...

[*] I found examples that showed classifying UDP, TCP, and ICMP. When you say to classify all types of traffic, should I classify those three, plus add a classification for DSCP? The mangle rule that I currently have for DSCP is: add action=set-priority chain=postrouting comment="From dscp high...

I need to set up QoS on NV2 wireless to prioritize VoIP traffic. We have DSCP enabled on the network. I set the NV2 queue count to 8, and QoS to Frame Priority. In a older post, someone recommended the following Mangle rules for the AP. I am not sure how these settings alone would enable NV2 QoS to ...

I tried it again and ran: /interface/lte/firmware-upgrade lte1 upgrade=yes I waited about 10 minutes and got status: failed. As soon as it started downloading, the LTE interface unregistered. I looked at the Traffic tab and saw that there was no TX/RX traffic at all. It looks like the upgrade is fai...

I saw that there is a firmware update available for my R11e-LTE-US modem. However, when I try to update the firmware on the modem, the cellular connection drops and it will not reconnect until I disable and re-enable the modem. The firmware update instructions say that updating over-the-air is the o...

On the R11e-LTE-US modem, is there a way to set the LTE band that it uses or a way to set an order of priority for the bands? I tried entering /interface lte set lte1 band=x but no matter what I enter for the band, it says "input does not match any value of band." I am using AT&T 4G LT...

Does the LDF LTE6 work on LTE networks in the USA?

1. Which LTE Category you are interested in most - CAT6, CAT7, CAT9, CAT11, CAT12, CAT16 or some other? Minimum Cat 6 2. 2. Which LTE bands and which Carrier Aggregation combinations should be supported? All AT&T bands in USA. 2, 4, 5, 12/17, 29, 30, 66. We have a few devices on Verizon Wireless...

No suggestions?

MikroTik hasn't had any boards with Mini PCI slots listed on the Hardware section of MikroTik.com for quite some time. We use the Ubiquiti XR9 radio cards on Routerboards for NLOS wireless, and they are Mini PCI. We used mostly the RB433 and RB411 series. Has MikroTik completely discontinued Mini PC...

I've been unable to enable Superchannel on any MikroTik ac radios that we've purchased. My organization is permitted to use 4.9 GHz, and I am trying to set a NetMetal 921UAGS-5SHPacD to 4.9 GHz. I've upgraded the license key to support extra channels, and it shows the "Extra-channels" feat...

Yes. It is our infrastructure. I wasn't sure if mixed mode would slow the network if there are no legacy clients. We now have more incoming bandwidth at some of our sites, so I am refining our backhauls to make better use of the bandwidth. I am going to convert some links to Greenfield mode to see h...

I am trying to maximize available speed on some backhauls. I've always set the band mode for backward compatibility even if all the radios on the link support the newest standard. For example, if all radios support 802.11N, I choose b/g/n. Is there any advantage to choosing N only or even AC only if...

I've been unable to get a Metal 52ac to connect to an access point on 5 GHz. with a 10 MHz. channel width. I've tried it with 5GHz.-A and 5GHz-A/N. It connects fine on 20 MHz., but we want to use a 10 MHz. channel to avoid interference. Does the Metal 52ac support 10 MHz.channels on 5 GHz.? If not, ...

I've seen it on hAP and RB751.

It is 6.42.6.

I've had several routers on which the bridges have gotten deleted somehow. Each time, the router had a bridge with Ethernet and WLAN ports on it. Users would report loss of connectivity, and when I logged into the router, the bridge was gone. The ports showed to be configured for a nonexistent bridg...

I've been using KeepAlive frames to eliminate the "ghosts" for several months now, and haven't noticed any problems as a result of it.

Hi Normis,

what you wrote above may look for someone that 6.40.8 (bugfix) is not secure too. I would like you mention that this bugfix release is secure too (blog needs correction too but it mention that 6.40.8 is OK at least).

So, is 6.40.8 secured against this vulnerability or is it not?

If you experience an interference issue with nv2 every few minutes, then I suspect you would be experiencing interference issues with 802.11 also. Things I would consider: - Run a frequency usage for several minutes - Are there other APs near-by ( any band ). - On every device, interface - Reset ma...

I tried the Sierra Wireless MC7750 on RouterOS 6.40.3 and 6.41rc32. It works on both of these RouterOS versions, but it connects at a slower rate than the Quectel EC21-V. RouterOS shows a connect speed of 3100000 with the Sierra Wireless, and 150000000 for the Quectel. I ran speed tests at testmy.ne...

On some of our 900 MHz. point-to multipoint links, the signal strength and SNR intermittently become poor when using NV2. We're using Ubiquiti XR9 radios. The problem usually lasts a minute or so, then goes away for a few minutes, then returns for a minute or so. If we use 802.11 on these same links...

I'm having this same problem on some of our radios with virtual APs. It seems that Having KeepAlive frames is disabled by default when I create virtual APs. This problem only happens on some of our virtual APs that have KeepAlive frames disabled. I've discovered this happening on different RouterOS ...

Thank you. I'll give it a try on 6.41RC. I'm pretty sure I was in DIP mode before, but that's also worth another look.

We never got it to work. I contacted MikroTik support via e-mail and sent them a supout, and they replied back and said that this looks like a compatibility issue with the modem's firmware. I'm testing a couple of different modems now - a Quectel EC25-V and an EC21-V. So far, the EC25-V isn't workin...

I upgraded the MC card firmware version and tried again. MikroTik recommended firmware 3.5.23.2 for the MC7700, but the newest firmware that I could find for the MC7750 was 3.5.10.13, so I upgraded to 3.5.10.13. It still doesn't show up as an LTE device. I haven't figured out how to determine whethe...

I am trying to set up a Sierra Wireless MC7750 on a RouterBoard RB912 to connect to Verizon Wireless 4G LTE in the United States. It doesn't work via the LTE interface in RouterOS, but I'm able to intermittently use it with a PPP client. When it works, my ppp-out1 interface status shows a local addr...

We're having a problem on the LAN at one of our sites in which we're getting an error that says "WLAN1: bridge port received packet with own address as source address . . . probably loop." The router that is logging the error is the first wireless client in the chain of hops, so it's the c...
