Then we will never find out at which transmit power these APs actually transmit. Transforms your numbers/chart in this moment to a apples with pears comparison. Helps you - but no one else. And one last note: you are observing RSSI on a client. Have you also compared the other way round? I have to ...

Linwood

Who knows what they are doing with power, I'm a little sad it didn't work out for you, I've waited a long time for something I can call I'm happy with as regards my setup, hAP ax2 and cAP ax, but it shouldn't have been that way. For a normal 4 bed house those 2 items are far in excess for me. I thi...

Linwood

A change of 3dbs is 1/2 the power. So 2 dbs is not trivial!! I was comparing it to my two tests, one had 15dBm and one had about 20 dBm, so 2db's is trivial in comparison. :lol: I don't know what "look at the IE's" means in this regard. I'm looking at what the devices see, which is what r...

Linwood

So the power is correct for 2.4G .... So the U6 is cheating? (seems unlikely given how prominent they are) Or quoting something involving antenna? But regardless... the CAP ax then appears at max, the U6 is at whatever it is at, and (for 2.4ghz) the CAP under-performs the U6 substantially when meas...

Linwood

What would be interesting besides these RSSI diagram: at which power level do CAP AX and U6 pro transmit? Can I trust their self report? As I looked this time I just forgot to mention it. The CAP ax says TX power is at 20. I tried forcing it higher (I put in 30) and the status under the wifi page c...

Linwood

Might as well finish it off. Got another U6 pro and put it in place of the Mikrotik (which was in place of the EAP1300). About 10dBm at 2ghz. All three AP's were physically in the same spot. Threeway.png Still baffled why when those AP's are offline it finds the much closer hAP ax2 but will never pi...

ranges: 2402-2482/20 5170-5250/23/indoor 5250-5330/23/indoor/dfs 5490-5730/30/dfs 5735-5875/14 So it is totally normal you get different signal readings for different frequencies. I have all devices set to USA, so I assume they conform to the (same) USA limits. I set up another test, and got frustr...

Linwood

Yes, thanks for sharing your particular experience. I did a comparison this year of U6+ and CAP AC over some weeks. I've recorded/compared wifi signal reception throughout my home. Once I was even running both APs at the same time, properly configured so channels did not overlap. I went through my ...

Linwood

Well, I am going to resurrect the original topic. One of the two CAP ax's failed (the ethernet port became intermittent and it kept dropping off). Amazon refunded me (said they couldn't just replace), which got me just enough initiative to try an experiment -- I bought a Unifi U6 Pro. One of the CAP...

Linwood

Yes, I read AC instead of AX. my mistake

I have an AC also I use with my telescope, so this was a good thought regardless, when I get some time I will go update it as indicated. Thank you.

Linwood

I realized I was not sure after the rewire if I was on the same port, so I switch ports to another one. This time I could not even connect. It would draw power, bring the port up (hard coded to 1g/full) but couldn't ping it at all, then the port went down.

So... dead. Or a reasonable facsimile.

Linwood

I have a bit more. The electricians showed up and did my low voltage pulls today. Before that, with the daisy chain order swapped, no failures. About 8pm or so I finished punching everything down and have nice shiny new cat 6, 23awg wire run to each, shorter runs, separate home runs. A bit after 10p...

Linwood

Yeah, I'm familiar, but really do not mind putting in more CAP's if I can get them to work and play well together. I also periodically want wifi outside (I have a portable telescope setup with a hAP on it that meshes when it can get a signal, plus it's a nuisance if I walk outside with a phone and i...

Linwood

The CAP one worked fine, the CAPSMAN did not, it shows red on the exclamation mark. I tried each phrase separately and none of them would take. I looked through the Command Line Interface document and did not see the exclamation mark discussed, does it mean "set to default"? I had tried &q...

Linwood

I have two CAP ax's running 7.15.2, daisy chained off a Netgear GS728TPv2 which is providing POE (combined draw 54v/13.8w, netgear has plenty of power remaining as all my cameras are yet to be installed), and they are not working well. The daisy chain setup is temporary until the electricians come t...

Linwood

I set up and experimented with capsman (wifi version), which is a whole different story, but decided to remove it. I am also trying to learn how to use the CLI more and the web less, and am comparing to hAP ax2 setups, and have a minor difference and cannot figure out how to fix it. It makes no diff...

Linwood

Thank you. Only providing 48v is perhaps consistent with no way to set it, but kind of weird that it has a column to show voltage.

But those converters look like a solution, albeit 30% the cost of the hAP ax2. But solves the problem. Thank you.

Linwood

I have two CAP ax and they work great with the 802.3at port on my netgear core (home) switch. I also have two hAP ax2's. Those are spec'd as "passive POE" with voltage limits of 18-28v. In the Netgear i have choices, including 802.3af, 802.3at (reasonably self explanatory) and also: Legacy...

Linwood

Yeah, I am coming to think that my new (old) home is not a great wifi environment. The walls are generally 1" thick, and seem to be 1/2" layer of conventional sheet rock, but what looks like 1/2" layer of cement board, kind of like what is sometimes put in wet environments. At least i...

Linwood

If true, it would be an "isotropic radiator" ...So I think we can conclude that it isn't. Would be nice if Mikrotik then published correct diagrams, and did not give incorrect answers. If your conclusion is right of course, that it isn't basically spherical. I also recently had another in...

Linwood

I have four MT AP's, they are in and running fine, though roaming could be better. I want to experiment with CAPsMAN, but having some MT experience in the past I do not want to count on the process being quick, and do not want to lose the existing AP's while I educate myself. I found I can run CAPsM...

Linwood

The only thing that comes to mind is that the application may not be measuring power directly but providing some kind of quality metric from which the RSSI is extrapolated. For example, it could be converting the agreed-upon PHY rate into RSSI. Typically, using a wider channel with the same power a...

Linwood

Hmmm.... I was running 20mhz channels because it was all IOT (on 2.4ghz) and figured I did not need the bandwidth, and it might cause less interference (to my neighbors or even my own). But I was having trouble with one device pretty far away from the furthest AP. Out of curiosity I changed to 20/40...

Linwood

I really wish the roaming information distribution was not tied to requiring provisioning with capsman. But I guess it was a convenient place to hang it. You don't need capsman for roaming. At the most bare level you can already use roaming within 1 AP and its 2 radios as long as they are using the...

Linwood

That helps, including the caution that I need to temporarily sacrifice one device to get this going. So what happens if the device (which will be an AP as that's all I have) running capsman fails, e.g. hardware, cable, whatever. Do the capsman devices still work normally with the exception of the ro...

Linwood

I have four Mikrotik AP's configured, 3 different types of hardware. I'm still struggling with how VLAN's are handled, but I have everything working nicely, including running ospf with my core OPNsense router/firewall for a mobile setup. I started looking, while setting up my new home, at faster/bet...

Linwood

I went ahead and bought a second CAP ax gen6. Not crazy about the distant performance in 2.4ghz, but the setup seems solid. They are in and configured, so I think all good. Thanks for the discussion.

Linwood

This conflicts a bit with a lot of postings I have read (I think from Mikrotek) that the radiation pattern inside is basically spherical and wall/ceiling do not matter. Source please. Can't make accusations of this nature without backing it up with sourcing. They are all over the place in discussio...

Linwood

I did another test this time sitting right beside each AP. The Engenius was 230/314 down/up at 5g. The CAP Ax was 313/486. So the CAP is faster with a very hot signal. The other thing I found in experimenting is that for a more distant signal (the original 40' or so) the orientation does matter for ...

Linwood

I thought VLAN 1 had more to do with security? I've got a lot of devices configured with VLAN 1 as the main internal network, I hate to change it. I also realize that it is more normal in Mikrotik to have trunk ports not include a native PVID (hybrid port), but I've got a lot that do that and spend ...

Linwood

Home network with lots of iot and a spread out old home. I have been using two engenius EAP1300's, one hAP ax2 and one hAP ac2. These latter are used for special purposes not general wifi. I also had a OpenWRT running on a Linksys 1900, that I needed to replace. I bought a CAP ax gen6 expecting its ...

Linwood

Thank you.

Linwood

Perhaps this nerdy explanation will help!! https://forum.mikrotik.com/viewtopic.php?f=2&t=173692 Thank you for that. It does help, especially some of the middle comments that parallel mine (i.e. there's just no reason for a simple, well known concept to be made so obscure). But I think I unders...

Linwood

Well, a lot more than an hour.... I merged in your changes one by one to try to understand them, and when all were there (except BASE which i didn't ask, and using 1 vs 11), it all worked, I can associate and get an IP from the right VLAN, the two switches in between it and my OPNsense are happy. I ...

Linwood

It's going to be another hour before I can try this but I have been looking at your config, and may I clarify something. I'm not questioning if it works but trying to test my own understanding as I want to build mental maps of how this works compared to other switches and routers... This appears to ...

Linwood

Ok, let me review it more carefully when this police department stops bugging me because their network is down, or more precisely when I convince them it's their upstream provider that is down.

Linwood

Are you saying RouterOS cannot handle it as a hybrid port? I can send both 1 and 134 as tagged on that port if that is preferred. But as to re-numbering the VLAN's: I have about 25 wired devices all around the house, using VLAN's 1, 131, 134, 135, 136. Most traffic is on vlan 1. I really do not want...

Linwood

I don't do any WiFi on Mikrotik, so not much help there, but as a general rule of thumb avoid using VLAN 1 unless absolutely required. Too many devices treat VLAN 1 as "special" and often don't behave as you might expect. For enterprise setups with cisco I follow that advice, unfortunatel...

Linwood

I will read this more carefully but you have lost me, especially here: Okay the challenge here is that ON ether1 incoming is not two vlans but only one vlan and basically untagged traffic. The feed from the uplink switch/router is a trunk port with two vlan's, vlan 1 (untagged) and vlan 134 (tagged)...

Linwood

I do a lot of cisco. A couple years ago bought a Mikrotik and loved it, set it up as a router for my telescope gear, multi-path, OSPF... worked great. No VLAn's, just subnets. Needed a new access point for home so bought a hAP ax2, I thought a real simple configuration - two vlan's, a few SSID's... ...

Linwood

Just for anyone interested, on Windows, with NMEATime2 as the GPS consumer, and compared against an NTP server to compare against and internet sync'd linux server, over an hour or so I'm showing 60ms +/- 12ms accuracy. Not great (not even good) for GPS time, but plenty good for a telescope at a remo...

Linwood

Thanks, I'm aware of the limitations of using a $12 dongle instead of a $300 time server, but I think I could still get something close, like 100ms accuracy. If I'm tracking stars a few seconds accuracy is fine. The fastest thing I may ever track would be something like the ISS, which can move at 1....

Linwood

I bought a GPS USB dongle and decided to give it a try. I enabled GPS and it is showing the correct lat/long and date. I have GPS set to update the system time. I realize that's a low resolution time, my intent is to use this with a telescope at dark sites, if I can get to a second or so that's grea...

Linwood

Thank you, @mkx. At home I can run NTP, but when at an astronomy dark site there's at best cellular, sometimes not that, but I'll look into something maybe to sync with the phone's time so at least with a cell signal I can get it to work. It's not worth a cellular subscription for the rare times.

Linwood

No one? Does that mean UPS GPS doesn't work? Or just no one ever cared enough to try?

Linwood

I have a hAP ac2 on a telescope tripod. I need an accurate time source when not internet connected (at that point this is used as an access point to connect the telescope's NUC and my laptop, phone, etc.). I actually do not know how accurate, but I figure GPS is better than the NUC's RTC. I see that...

Linwood

Hmmm... so it doesn't work if the 2.4 and 5ghz connections are to the same AP. But when they are to two different AP's (on the same VLAN) it does work. I still don't get why that doesn't loop.

Linwood

I have something working well, and do not understand why; I think I fail to understand some basics of wifi networking and would love advice. Basic setup: Home router OpenWRT, connected to a Netgear switch, in turn connected to two Engenius EAP1300 AP's, one at the front, one the back of the house. A...
