I am wondering if anyone has been able to design a reliable configuration for a remote LTE camera for jobsites that has the ability to send snapshots to a surveillance server in order to monitor a job site remotely?

Hello, Just purchased some new SXTsq AC units to replace all of our older RB411 with R5H cards. I am able to get the new PTP links works, but I have noticed that they connection is not consistent. First thing that happens on some of the units is that the link disconnects randomly, then reconnects. T...

danletkeman

I did find that one, but i'm not sure a 120 degree would be the correct antenna for a short point to point. I was thinking more like 15 degree.

danletkeman

Thanks, but I am looking for an antenna only. Also I would like a directional one for a point to point link.

Hello,

I am looking for a low gain dual pole outdoor antenna. I have a few net metals's that I would like re-purpose for a very short link (1/2 km) and my current 30db antenna's are too large. Does anyone know of a 5-10db antenna that I could use with these radios?

Thanks,
Dan.

danletkeman

You think with another netmetal from the other side of ptp solve this ?

Yes. I tried this too, and had odd results. Both should be the same unit.

I just did this upgrade on two RB411GL boards and they didn't come up after the reboot/upgrade. I had to hard power them off at the sites and power them back on.

Mistakes happen. I'm sure it will be resolved.

Do you have a list of serial's that might be affected? I just bought a bunch of these and luckily it's snowing here, as it's cold outside. I'm just wondering if it will happen to me in spring time.

danletkeman

one more thing. If that dont help try one addition thing. Disable all data rates for N and use AC only and set the mc7 for basic and all chains. This will get you less transmit errors if you have interference.

Can you post some screen shots of your config?

danletkeman

Does anyone know how to get the spectrum analyzer to work? Looks like its not supported. Is this correct?

Normis says they will get it working yet, its on there too do list.

Sure its config mistake, but your conf looks ok, i have a 60km link with the net metal 5 ac, and i love it, btw im using Jirous Antenna Ubiquiti antennas also work ok but no the same as Jirous cant post img forum changes Could you try attaching images now? I am curious to see your config as well.

I have found that there is some sort of speed negotiation issue with these boards or possibly the injector I have. If I set my rb411gl to 1Gbps Full Duplex manually it does not linkup.

danletkeman

I have two APs with the same SSID, same frequency. You don't want to run the access points at the same frequency. You are creating interference that might make it roam slower. Normally in an enterprise WLAN you have a wireless lan controller to handle layer 2 and layer 3 fast roaming. I'm not sure ...

danletkeman

So from what i understand you want to trunk the vlan's from one cisco switch to the other? You don't need to created different ssid's on the mikrotik radios. Make sure the mikrotik radio's are transparently bridging. Then just create the trunk setup on both cisco switches just as you would if they w...

Hello,

I'm interested in buying a superchannel license for our routerboards and using 5500-5700 in 40Mhz channel's. I'm just wondering if anyone has done this on the R5H cards.

Thanks.

danletkeman

An RB411AH "G" would be nice because we would not need to replace all of our existing enclosures. We are using them mostly for backhaul's and only need one card anyway.

danletkeman

Can you hookup two 2.4ghz antennas to the same r52h card? Or is the second antenna connection only for 5ghz?

danletkeman

I have not tried it, but it should work.

I would recommend eigrp with equal cost load balancing instead of etherchannel if you have layer 3 switches.

danletkeman

Just a quick look at the elevation data, it looks like there is a possibility of a 341km link (if those places are accessible).

Otherwise I don't see that there are any possible locations.

Just off the top of my head.

If you traffic flows fine I wouldn't worry about it. They must have some kind of firewall rule to block trace routes or something of the sort.

I've some experience with links handling about half that number of users.
