@johnpoz You use beta, do you recommend it? and why is there a LAN with dhcp, as there are no ports to connect?
-
Yeah I have always run the beta.. This is my home network.. I have no issues with some of blip or something - but in the years been running unifi.. I don't recall really ever having anything that was of any real issue.. There have been some beta's where the speed wasn't as fast as other firmware releases.. But they normally correct in the next update, etc.
I run the beta controller as well.. 5.14.9 currently.
The one thing nice about running controller on VM, is just take a snapshot before update.. And if goes south, just restore the snap and back to where you were.
why is there a LAN with dhcp, as there are no ports to connect?
Yah lost me - not understanding what your asking there? Oh the controller run multiple things, switches and their USG (router) which can provide for dhcp and other networks. Notice the USG required next to that ;)
-
@johnpoz Oeps missed that, there are some other settings that are for other gear, like DPI (deep packet inspection), it is on by default and as I don't have a unifi security gateway I will turn it of.
Strange thing I have ra0 to ra4 and ra4 is ra4 e2:63:da:40:11:6c element-64e46abdc079e335 11 ? So although I have mesh/uplink disabled ?

You can turn those off - those are for adoption of specific unifi gear, like their new plug and stuff.. If you don't have any of that gear you can turn those off. Just delete them if you have already unchecked the setting.
-
@johnpoz I can't remove the element wlan, maybe it's gone after a reboot of the device or do you have a ssuggestion?
Btw tommorow I am busy, friday more time, one question, when I adopt the second nanoHD what will it do with the ip address as I now have set it static?
-
Huh? The static IP is per AP, by default the AP will come up with dhcp.. If you want to set it static then you would have to set it per that AP..
This should help in removal of the element ssid

@johnpoz Thanks will try it friday, got to move now, "grazie mille"
for all the explaining and your time, super...I am beginning to like unifi -
@Qinn Just to chime in quickly from the left field: I'd also advise to reconsider the need for 4 (or more) SSIDs as every SSID you use slows down the bandwith of your WiFi so the less you use, the more you get on your devices. If you do it "right", all you need are one or two SSIDs anyway. One running Radius based VLANs (perhaps together with freeradius on your pfsense) and one for those old/dumb devices, that don't work with AES-Enterprise WiFi (User/Pass instead of shared key). :)
-
@JeGr Thanks for the hint, I will reconsider.
-
To chime in on that as well - if you really really want to get fancy.. You might even be able to get by with just 1 ssid.. where you assign vlans based on mac of the devices.
Maybe just 2 if you want a enterprise auth ssid, and for those iot devices and such just use psk, I did a test a while back they first came out with the dynamic vlan support, and I did get it to work based on mac for psk devices..
I was thinking at one time to go down this path.. But haven't gotten back to it ;) Lots of devices - all working, segmented out how I want.. Haven't found the motivation to change it all up just to drop a couple of ssids ;)
While sure the fewer the ssids the better if your looking to max tweak your setup.. A couple of extra ssids not going to be a big difference in overall performance ;)
Here this might help
https://help.ui.com/hc/en-us/articles/360015268353-UniFi-USG-Configuring-RADIUS-ServerYou can use freerad on pfsense for this vs using the radius server of usg..
I currently use 4 ssids = 4 different vlans
1 wpa2-enterprise with eap-tls auth, this is for my trusted devices. My phone, Wife's phone, my laptop, my tablet, etc.
2 wpa2-psk for iot devices, thermostat, alexa devices, smart bulbs, the like
3 wpa2-psk for roku/tv stuff. My harmony remote, tv, roku sticks
4 wpa2-psk for guest devices.. Even setup QR code on a business card I can give guest so they can just scan the qr code with their phone and get on.. Zero reason for them to type out the very long and complex psk ;) -
Thanks guys and thanks john, for now I will stay on 4 ssids = 4 different vlans ;)
@johnpoz First things first reporting back, I tried the link to remove the element ssid using the classic settings, alas no avial. Then the new settings and deleted it, worked like a charm.
Second, I have encountered a strange problem and after more than 2 hours I just can't quite put my finger on it. I have 2 nodes each none connected to a different wireless bridge, both of the same vendor, both with the same firmware version. They are in different vlans, until I switched over from Engenius to UniFI the both worked like a charm. With UniFi one is connected to the AP and the other one not. It doesn't seem to be related to the wireless bridge, because when I switched the wireless bridge that could not access the vlan to the other vlan it connected, I have no idea why it cannot access the one vlan an no the other?
btw is see this
Channel Auto(8(6,+1) HT40What channels are these?
-
@Qinn said in Seamless roaming:
Auto(8(6,+1) HT40
Yeah that is horrible setup.. HT40 is not a supported option on 2.4... I would HIGHLY suggest you set 20 VHT on your 2.4 even if some clients and vendors say they support this.. It is not a standard that is supported and it will and does cause all kinds of issues.. And also use of anything other than 1,6 or 11 on 2.4 is just pointless.. Even if some auto config says hey lets use channel 8.. It's Borked!! with 2.4 the only channels that do not overlap are 1,6 and 11..
I have no idea why it cannot access the one vlan an no the other?
Your going to need to give a bit more detail on how exactly you have this setup.. What are you rules on the vlans you created? How you have it actually wired up, etc. etc..
These wireless bridges? How do you have them connected? What make/model of these devices? You have them connecting to your AP ssids? and then what wired devices hanging off them?
-
@johnpoz Thanks I will change this setting to HT20
After 4 hours I found it
High Performance Devices (Beta): Connects high performance clients to 5 GHz only... the above feature was enabled in the vlan that the wireless bridge could not access, once removed it can access
-
Do these devices support 5ghz? That is something like band steering.. Trying to push clients to 5ghz.. but sure there could be problems with that depending on the client.
-
@johnpoz What do you say about the transmit power, auto, high or manual? btw no the wireless bridge only supports 2.4 and never enabled this on on that vlan, strange...
-
I have mind set manually.. But I have a small house and not a lot of distance between AP so 2.4 is always set to low..
You can play with that.. Transmit power is a very misunderstood setting - many people think hey should always be HIGH.. That is not true at all.. Doesn't make any sense for a client to see an AP 300 ft away, if its little transmitter can not get back, etc.. So power should be setup for your layout and clients and possible interference/walls, etc.
You can try just auto and give it some testing.. And then only tweak if you run into issues with connectivity or roaming problems.
-
@johnpoz Could you explain me why not use HT40 on 2.4, it means higher speeds. For 5GHz you use 40HT? btw why can't I set the both channels manually, so like 6+11, here I have no interference at all.
-
There are only 3 non overlapping channels @ 2.4 Ghz 1, 6 & 11 or 1, 7 & 13 in Europe.
If you set HT40 @ 2.4 Ghz you'd have even less non overlapping channels, both these are HT20 @2.4 Ghz.
-
@NogBadTheBad said in Seamless roaming:
If you set HT40 @ 2.4 Ghz
True - and its not a valid standard either.. Even you had no other networks in the area at all, and only 2 AP or even just 1.. its not a standard - and will be hit or miss based upon your client.. So ok if you have 1 client and it supports it, and you have zero other wifi in the area on 2.4 you might be able to get away with it.. But if what your after is speed 2.4 is not the way to go anyway.. .You should be on AC on 5ghz ;) Going to just blow away even a 3x3 2.4 client on 40mhz..
2.4 best you could get with 3 stream client.. Those are like unicorns in the first place, rare as F.. Is a 450 PHY with short GI and 40 VHT.. With 2 stream client your talking only 300 PHY.
With AC 2x2 client using just 40 vht can get 400, which is very common.. Or even more common is use 80 VHT (standard) on 2 streams a 867 PHY which over double would could ever get on 2.4 even using the unsupported and non standard 40 vht on it..

@johnpoz Second one up and running, adoption went smooth
