Seamless roaming

Install whatever OS you want ubuntu, centos, debian - then install the controller package.

So does your docker get IP that your host is on when you do that? If so then it would be on the same L2 and you would be able to see your AP, etc.

The 2 nanoHD-UAP's are connected by UTP and connect to a managed switch that's connected to pfSense.

The nanoHD have 4 VLAN's

192.168.5.x - WLAN
192.168.3.x - P2P
10.0.0x - Guests
172.16.20.x - IoT's

pfSense and the nanoHD's are in the LAN with 192.168.1.X

Is it maybe an idea to give the nanoHD's an IP that is in the same subnet as the Synology namely WLAN?

johnpoz

You want the AP and the Controller in the same L2.. The problem with docker is there is normally a nat this going on.. Which are not the same L2..

If your AP and controller on not on the same L2 then you need to use L3 adoption..

example

ash-4.3# docker network inspect bridge
[
    {
        "Name": "bridge",
        "Id": "0f675293ee5c05dfffab0e87768f200646e3355732497445611ae250a0838719",
        "Created": "2020-06-26T05:22:38.90432023-05:00",
        "Scope": "local",
        "Driver": "bridge",
        "EnableIPv6": false,
        "IPAM": {
            "Driver": "default",
            "Options": null,
            "Config": [
                {
                    "Subnet": "172.17.0.0/16",
                    "Gateway": "172.17.0.1"
                }
            ]

then ip masquerade is used to match up ports on the bridge network... This i not the same L2... if docker does put this in the same L2 then it amounts to running multiple L3 on the same L2 which could sure prove problematic for L2 adoption of the AP in your controller. Are your APs adopted by your controller?

I would suggest if you want to use your controller in a docker, and L2 adoption is not working - to use L3 adoption..

But yes generally speaking your controller and AP (managment ip) would be in the same network.. Unless your wanting to put your management IP of your AP on a vlan.. This vlan could be in the same L2 as your controller, or could be different - which again then you would need to use L3 adoption for your controller to manage your controller.

My controller and AP all run on my native vlan (untagged) 192.168.2/24 - I then have a wifi SSID that is in this vlan, this is the vlan I connect my trusted devices to... And then I have 3 other vlans (ssids) on the AP that are in different vlans 192.168.6/24, 192.168.7/24 etc..

@johnpoz Thanks. I finally decided to move the Synology 918+ over to the LAN, so it's in the same subnet as the two UAP-nanoHD's. Then granted the WLAN subnet access to it, installed docker and the container. It's running nicely for 2 hours.

Nice.. Yeah I have added a couple dockers as of late as well ;)

I would be up for moving the controller to docker - but I also leverage that same VM as my linux box when wanting to do something I just ssh to it.. Also as vm its easier to just take snapshots when going some sort of update with controller - as mentioned I always running latest beta version..

The updatetool is slick little tool for keeping plex ratings updated with the latest numbers from imdb (runs every 12 hours).. And getting the latest ombi (plex request system) beta up was just easier to do via docker..

Glad you got it sorted..

edit: Looking at the unifi controller dockers I see, I don't see any on the 5.14 beta line.. So for "me" that would be a reason to just stay with using vm.

Qinn

@johnpoz From what I read here beta and docker can play well together https://www.reddit.com/r/Ubiquiti/comments/7tcyjr/unifi_beta_running_in_docker_on_synology/ maybe you wanne give it a try?

btw you are using UAP/USW Firmware 4.3.19.11295?

johnpoz

No my firmware is 5.20 told you always run the latest betas..

Qinn

@johnpoz ....did not active the early access setting in my config, thus could not see any beta's. So your on UAP/USW Firmware 5.20.0.11910 ;) btw is there any relation between the firmware and the controller version?
So could I use this beta firmware with the controller version (atag_5.13.29_13635) I have running on docker or do I need UniFi Network Controller 5.14.15, no idea if this one is available for docker?

johnpoz

You can run beta firmware with the stable controllers sure.. Its just sometimes you won't be able to do X that is in the beta firmware withou the beta contreoller.

Qinn

@johnpoz I see this Firefox_Screenshot_2020-06-30T09-44-44.362Z.png

any idea why?

johnpoz

Do you have a USG.. That is only available when you have 1 of their routers..

None of this stuff is going to show anything unless you have the stuff

Keep in mind the controller is meant to control like all of their stuff, not just AP..,

If you don't like seeing it just use your fav browser tool to hide it.

Qinn

@johnpoz you mean hide the elements? I would be nice if you could remove these widgets in the controller.

JeGr

Yes that would be really nice. Or if they would simply open up that speedtest stuff and just run it on the controller if there's no USG so you can just have some values there.

Anyway it is looking like this with one of their new UDMs:

So not really missing much, but it would be a really nice touch if they would support speed tests or speed displays via an API or external method. But as they of course like to sell their own gateways ;) I'm not counting on it :)

Derelict

"Seamless roaming" has been a thing for like 20 years.

Put different access points up with the same SSIDs on the same layer 2 networks and have a cocktail.

Controllers can try to steer clients to different radios but it is ultimately up to the clients.

Kind of surprised Ubiquiti hasn't figured this out yet.

JeGr

@Derelict said in Seamless roaming:

Put different access points up with the same SSIDs on the same layer 2 networks and have a cocktail.

AFAIR that's only "roaming" and yes, that's depending on the client only. Seamless roaming as I recall is an active process that requires APs and controller(s) to steer the client to another AP if he goes out of range of the last one. Last time I deployed WiFi that would require it (due to phones would be using WiFi / VoIP) that was not the same thing but perhaps I'm just old ^^

Qinn

@Derelict they even introduced this.. Firefox_Screenshot_2020-06-30T11-56-26.032Z.png

Qinn

Can anyone enlighten me what this option is/does? .... as I have no recollection that I enabled it?

Click on the (!) it's not enabled out the box AFAIK.

https://help.ui.com/hc/en-us/articles/115006559827-UniFi-802-11-Basic-Supported-Rate-Controls#2

JeGr

The first one: (no need for such large pics, just cut them down :))

That's client side fast roaming / BSS switching. If the client supports it (modern ones should) it can fade over the connection from one AP to another without loosing connection. That's fast / seamless roaming and that was intended like I said for VoIP or other continuous protocols that react badly to short disconnects.

The second one is often due to automatic connection optimizing selected as most modern clients don't need to support all old (e.g. 802.11b) speeds like 1/6/11Mbps. If one doesn't need those it can speed up the radio/SSID as it's unneccesarry to send the appropriate beacons. That can improve the performance of 2GHz Wifi especially in zones with many overlapping ones. But if you have (stone age) old WiFi equip that only talks b or b,g standards, it can make them unable to connect.

Also AFAIK your setting is indeed default with newly created SSIDs (or only when auto-optimizations are on, don't know exactly). The SSID / radio on the dream machine of my brother's looks the same and he doesn't know enough to configure it ;) So that seems pretty default to me :D
