Radar detection Chaos Since 6.40.4
by Matt Perkins 20 Oct '17

20 Oct '17

Hi All, Since the upgrade to 6.40.4 which has almost become a pseudo requirement since WPA2 announcement we have had a large number of sites detecting radar with false positives. Other then enabling super channel or perhaps switching to manual tx power and manually putting in the Australian card rates. I see no way to disable it. Does anyone have a better solution that wont get the ghost busters around to shut down your ap. Matt. -- /* Matt Perkins Direct 1300 137 379 Spectrum Networks Ptd. Ltd.

krack
by Ben Williams 18 Oct '17

18 Oct '17

Hey, What should we do to mitigate against the krack vulnerability in our mikrotik gear? I checked the changelogs at https://mikrotik.com/download/changelogs/, but there's no mention of krack (assumedly because the last updates are from before krack was announced). I assume people are working on a firmware update? - Ben -- -- echo [q]sa[ln0=aln256%Pln256/snlbx]sb241167078674140849351213545168413280214786211741720960170477998338109578719788558437971008954751099682787776927198532026019640182283695835073769037269976965492880188752740629807625756643115316959456234027360849928332596130768194snlbxq|dc

Can't connect through Winbox/Dude
by Russell Hurren 05 Oct '17

05 Oct '17

I have an intermittent problem where some routers stop allowing Winbox or Dude connections. At the moment I have a CCR1009 at a client site that's working perfectly and I can ssh into it, but I can't use Winbox or the Dude. If I reboot it, it'll come good (but I'll have to do that late at night). I've had some x86 routers do the same thing. I can't see anything obvious in the logs or active connections. The problem occurs with multiple different ROS versions. Does anyone have any suggestions for troubleshooting this? Thanks Russell

Mikrotik AP range
by Erin Murphy 22 Sep '17

22 Sep '17

Hi all I've started to use Mikrotik on a regular basis on my installs and have found the range on their AP's are far short of some of the other brands I've been using. Have used Unifi, Luxul, Ignitenet etc and now Mikrotik. Have found I need up to 3 WAPACS where I would normally use 1 with another brand. I have regulatory country set in my Capsman controller and tx strength at default. Is this what others have found? The price of Mikrotik still makes it viable but the roaming between 3 AP's as opposed to 1 is a worry. Long time stalker, first time poster.

smartphones connected to directional antennas
by Andrew Radke 21 Sep '17

21 Sep '17

Hi all, I was wondering if any of you have had any experience, or done any testing, of smartphones connected to APs with directional antennas at multi-km distances. I have an extremely radio quiet rural valley that I’d like to push wireless signal into for VoIP but over distances of 1 - 5km. There would be APs on the range beside it with clear line of sight into the whole valley. To help reduce the issue of the hidden node problem (if any devices can even connect at all) I’d look at putting bandwidth limiting on each connected device of maybe 100-200 Kbps to keep the throughput of each one, and therefore collisions with other transmitting devices, as low as possible. I’d also only allow VoIP traffic through the router or AP to make sure that downloading emails doesn’t ruin their phone calls (or maybe just limit non-VoIP data to a very small fraction of throughput if needed). The VoIP client will mostly take care of jitter and buffering, and almost anything would still be better than than not even having a 3G signal as is the case at the moment. Obviously there are a mountain of gotchas and it depends in this scenario but I’d love to hear from anyone that has tried something similar. Thanks, Andrew

VLAN support with RB750Gr3
by Chris Herrmann 18 Sep '17

18 Sep '17

Hi all, I've ended up going for the RB850Gx2 with Mike because it has the Atheros8327 switch chipset. This is the same as the RB2011 unit that it's replacing, which means that the switching performance & configuration should be closer and the 850 has faster IPSEC than the 2011. Cheers, Chris

Dynadish Images
by Paul Julian 15 Sep '17

15 Sep '17

Hi All, just wondering if anybody has an image of a Dynadish installed on a mast somewhere I could use ? We are doing some land access notices and like to include photos of the gear we are installing as part of it but haven't actually installed one of these as yet. Thanks Paul

VLAN support with RB750Gr3
by Chris Herrmann 12 Sep '17

12 Sep '17

Hi all, Looking at upgrading from RB2011 to this model to improve IPSEC throughput (don't need wifi on the unit). Sounds like the RB750Gr3 is much faster than the RB2011 for this... but... I've stumbled across some posts with people describing issues using VLANs on the RB750Gr3. The posts in question didn't appear to be resolved... so I figured I'd ask here - can you use vlans safely with this unit and <latest stable software/firmware>? The RB2011 has been working perfectly with this for years now, but we'd like to push far more than the 16Mbps that appears to be the ceiling we get pushing IPSEC packets. Anyone using it for this? Thanks! Chris

LAN support with RB750Gr3
by Chris Herrmann 11 Sep '17

11 Sep '17

Hi all, thanks for the replies. Mike there's a comment from a Mikrotik staff member on this post: https://forum.mikrotik.com/viewtopic.php?t=113724&start=50 and other similar pages. The exact comment on this from MK specifically is: "RB750Gr3 switch chip does not have full VLAN tagging/untagging support yet, it is planned to implement it in future. Currently, you should use RB750Gr3 switch chip only for basic switching." that was in November 2016, so was hoping that maybe things had changed since then. as for whether I'll go a virtual or hardware switch I'm not sure at this point. In general I'd try and use hardware support for things because dedicated ASICs tend to give you better performance than relying up the main CPU to achieve a feature (this isn't a MK specific comment btw, true of any vendors I've come across). So currently I'm using the switch chip vlan not routerOS virtual interface tagging. If I could continue to use it, that would be my preference... but if not does it change the actual config design a lot? I'm guessing once you have the VLAN interface up then all your other rules are still referring to object(x) which just happens to be a virtual interface instead of a switch chip vlan? Or not...? Thanks! Chris
