Well, if you have a noisy NAS and want to drown it out, get the CRS310. The CRS310 fan will do that for you. It's certainly not a product you wany inside a house or facility. I had to move it to the garage!

I ran into the gentleman responsible for configuring the google network. He was X Digital, which I believe is where Is-IS came from. Google is all IS-IS.

No POE out on 5009? Want poe in to power 5009 and POE out to power Ubiquiti radio. Want to get away with a single Cat 6A cable to the site. The new Ubiquiti airfiber 60 HD, non bonded channel setup , will do 2 GB/S full duplex, so the 5009 2.5 gig ethernet port will support that. So with the 5009 SF...

The usage of frequencies above the 5.9 ghz space isn't easy in the USA. Sure, the FCC added additional frequencies, all the way through 7 ghz, but it's not as simple as just having a radio that works in that frequency range. Mimosa for example already run out to 6.4 ghz, but they still can't ship th...

Thanks for the response. Is that a constraint within the CRS configuration, the user equipment, or both.

Tested L3 HW offload on CRS305 using Routeros 7.1beta6. Got just over 200 Mb/s. Yep, bits. Replicated this test run on the CRS317; https://stubarea51.net/2020/10/12/mikrotik-routerosv7-first-look-l3-asic-performance-testing/ Here is the config. /interface bridge add mtu=9216 name=bridge1 vlan-filter...

I'm not good at explaining, English is not my mother language.
(Non-RouterOS related)

You must work in the documentation department:)

comet48

So announcement says CRS309-1G-8S+IN, CRS312-4C+8XG-RM, CRS326-24S+2Q+RM and CRS354-48G-4S+2Q+RM for L3 offload but CRS317 mentioned above as working.

I have CRS326-24G-2S+ (arm). Will it take advantage of L3 offloading? If so, what else will?

comet48

OK - although I wasn't able to find it in winbox, I was able to change it in the terminal window

/interface wireless
set [ find default-name=wlan1 ] antenna gain=0

The radio is now running at 30 dbm.

comet48

In the USA, in PTP UNII-1 allows a maximum EIRP of 53 db, and UNII-3 allows unlimited as long as radio gain is 30dbm. I used to get the radio power up by reducing the Antenna gain parameter to 0. The option to do that appears to have disappeared in radios with attached antennas. So while I'm here wi...

Looking at connecting two sites ptp. Going to use ospf because hopefully this is the first of many. Both sites are using 192.168.1.0/24 subnet for LAN. Whats the best way to handle this without having to change one of the subnets. 100 plus devices at both ends. Mikrotik routers both ends, Mimosa rad...

Have same question.

comet48

I'm getting the same issues with a recently purchased 4011 with wifi. Running 6.46.4 firmware and software. Can't get through watching a movie without it rebooting. What's the RMA process on this these units?

comet48

2Jarek,
So what Cambium software, and will it run on the current Mikrotik LHG products?

comet48

Here is the Cambium 802.11ax roadmap.

How about something like this from mikrotik!

2Jarek,
Which cambium with which Mikrotik?

What's new in 7.0beta4 (2019-Dec-06 13:21):

That's the way I read it. Linglish is hard to follow:)

I have to agree - nice product for 10 years ago!

comet48

Block diagram does not show one!

The FCC is about to open up the 6 GHZ band - 5.925-7.125 GHz. Pretty much the same rules as the 5 GHz band. Obviously a big plus. Where is MT on support, and what will it look like? Combo 5 and 6 Ghz radio? New product, or firmware change to current product?

comet48

Fantastic explanation. One can only wish MT documentation was more like this. And, it's in real English!

comet48

Response from MT support. "If you adjust the wireless configuration thew it is possible to use max Tx power without problems." What a horseshit reply. When you select regulatory domain, the expectation is that you are going to get the maximum allowed EIRP, not 25% of it. IMO, this shows a ...

Check out the mimosa design tool. Uses a 36 dBm EIRP for PTMP designs.

comet48

5785/20-eC/ac(11dBm) So antenna gain is set to 19. MT reduces the output power to keep the EIRP to 30 dbm, 6 db below the FCC limit. Additionally, changing to PTP mode still leaves it at 11 db. It appears that to get the legal limit afforded by the FCC in the USA, you need to reduce the MT assigned ...

comet48

More curious issues. The Dynadish 5 has antenna gain 25dBi, and if you look at the transmitted power, its choked back to 5dBm. Thats a total EIRP of 30 dBm. But the FCC allows 36 dBm EIRP for the worst case PTMP applications, and a minimum of 53dBm for PTP. Why does Mikrotik reduce EIRP 6dBm below t...

https://apps.fcc.gov/kdb/GetAttachment. ... mber=27155

Looks like no limit on antenna gain on PTP 5725-5850

comet48

So I'm confused - what's new? Is the 30dBm EIRP? Or transmit power? Because the rules state "Several of the FCC part 15 rules govern the transmit power permitted in the ISM bands. Here is a summary of those rules: Maximum transmitter output power, fed into the antenna, is 30 dBm (1 watt). Maxim...

comet48

I see the lowest setting for antenna gain is 0, so 52dBm. The other question is whether these MT devices will operate at 200 watts reliably for an extended period?

comet48

This was the response I received from MT. "To comply with the regulations by example if you have a high gain antenna you need additional to specify the antenna gain for the device and then the Tx power will be limited by the values specified." So to interpret this to mean that to get 53 dB...

comet48

Yes - 17 dBm is a big difference on the PTP links.

comet48

"If your equipment is used in a fixed point-to-point link, there are two exceptions to the maximum EIRP rule above: In the 5.8 GHz band the rule is less restrictive. The maximum EIRP allowed is 53 dBm (30 dBm plus 23 dBi of antenna gain)." I noticed this using the Mimosa design tool. PTMP,...

comet48

In the USA, max EIRP is "Maximum transmitter output power, fed into the antenna, is 30 dBm (1 watt). Maximum Effective Isotropic Radiated Power (EIRP) is 36 dBm (4 watt). You can obtain the EIRP by simply adding the transmit output power, in dBm, to the antenna gain in dBi (if there is loss in ...

I solved the problem with longitude in USA by proceeding west from Europe to the USA. It then calculates longitude correctly. Love the calculator. Gave me some idea of how some of the wireless products worked with each other. I presume it doesn't take into account trees or buildings. Plus one on add...

comet48

The problem is that it is calculating the longitude incorrectly. Like 238 for san francisco, instead of -122

comet48

Same problem here. Works fine except North America. Got it working yesterday for awhile, but tried it this morning and no go. The elevation display fails to update, both height and distance. Stuck at 1km right now. If I go back to Europe, stock there too. Did a reset in Europe, started working OK, t...

I was looking to deploy some Mikrotik wireless gear. After reading this thread, I think I'm going to investigate other options!

comet48

First post ! OK, so I've purchased an hEX S, an hap ac2, and an RB260GSP. I've never worked with managed switches/routers before so it's a bit of a steep learning curve. We are looking at installing a community fiber project, and it looks as thought some of the Mikro Tik products might fit. I'm usin...
