What would the back to back noise be of these units? Would they be able to work back to back on a pole in the same frequency? We only have 3 to use and if we have a tower with 4 sectors plus maybe one or two P2P's leaving we already have to start to make a puzzle. Some more antenna and radiation ch...

Re: New Wireless package

Would you please post the exact method used? I would be happy to try and compare. Right now I am runnning NV2, and my configuration is a bit complex, BGP-VPLS connecting several networks at both sides of the link. But I think it's better not to use the own routers bandwidth test. RouterOS 6.13 with ...

Re: New Wireless package

Confirmed with OmniTIKs.

I have the superchannel license, and I can't enable the custom 30 MHz channel width with wireless-fp enabled. Disabling wireless-fp and enabling wireless it works perfectly.

Re: Known issues and bugs - a list

Perfectly stable wireless link between two Omnitiks works perfectly with RoterOS <= 6.6. The link is table, with CCR > 90 % most of the day. After upgrading to 6.7, it begins to develop problems. Several days after the last reboot, packet loss appears. A reboot of just the one configured as an AP so...

Re: 6.9 released!

I think there's some bug in the wireless subsystem, introduced in version 6.7. I have two Omnitiks used to establish a link across a street. Nothing fancy, it works solid with NV2, CCR between 80-100% depending on when I open a window (both units are indoors, placed close to the windows). Until I up...

Re: Feature request: BGP flowspec (RFC5575)

Right now not many transit providers support it. From the Mikrotik side, the priority would be to implement the BGP exchange, even if RouterOS doesn't have the mechanisms in place to actually apply the rules, but at least enabling the RouterOS to send BGP flowspec advertisements to the transit provi...

Feature request: BGP flowspec (RFC5575)

Are you planning to implement this? For unfamiliar readers, roughly speaking, it uses BGP to distribute filter specifications. It's very useful in DDoS attacks, allowing you to send "firewall rules" (matching on source and destination addresses, protocols, ports, etc) to your BGP peers/transits, so ...

Re: As we would like to evolve the wireless

A very important feature would be programmable hardware attenuation for the receiver part. That would improve the performance in high interference places. You would be able to use a higher transmission power, so that your signal would stay above the interference, at the same time avoiding the receiv...

Re: How to measure traffic to an ASN?

Hi,
I'm trying to get a peering agreement with a local Content provider, but I need to measure the traffic from my ASN to their ASN. What method or program do you use to measure ASN to ASN traffic?
For that purpose (and many others!) Netflow is your friend.

Try nfsen (nfsen.sourceforge.net).

It should be controlled for each interface, instead of being an all or nothing parameter. In a provider network yo...

I don't understand why you are using WDS. If they are connected to the same wired network, just set the same SSID and, of course, the same authentication parameters. The clients will connect to the strongest signal.
