Ubiquity AP,Router&Controller Setup Problems

[DomDom3333]

Hello,

I've been running my house on UBNT hardware for a while. I set it up a while ago with 4 APs connected directly to my ISP router. This worked very well and I've been using them ever since without touching the controller software. I added a UBNT EdgerouterX down the line and that was fine too. Today I added another AP to cover a dead spot that is now in use and to set it up, I've had to reinstall that controller software. Ever since I adopted the APs into the controller, all things WIFI have just not worked.

 

The Problem:
Some devices stay connected (2 Tablets in the house), others stayed connected for a bit and decided to disconnect later and others instantly dropped connection (a dektop). When you try to connect to any of the APs, windows says that it cant connect and Android just doesn't. No error nothing. Cable connections work like always though. 

Things I've tried:

• - Update everything - nope
• - Various google searches making me change many settings - nothing
• - Restart of all hardware and software - no luck
• - reinstall of the software and hard reset of the hardware - same thing
• - more frustrated googling and I'm all out of ideas. 

I'm not particularly good at networking but know the basics. This is a step above me seemingly. Im not even sure what information to provide here to help you.

Hardware:

• 5 x UBNT AC Lite (Firmware 4.0.42.10433)
• 1 x UBNT Edge router X (Firmware 1.10.08)
• 1 x Generic ISP modem
• Controller Software running on a Cable PC connected to Edge Router (Version 5.10.25 (Build: atag_5.10.25_11682))

 

Setup:

• Internet -> Modem -> EdgeRouter -> Switch -> APs & House
• EdgeRouter only hands out anything on 255.255.1.X
• Modem is only on 255.255.255.0.X (which is only the Edge Router)

If I understand this correct then the Edge router Should be the DHCP server. I might be understanding something wrong here though since it seems to me like the controller software is emulating a router? Giving out IPs and managing devices etc. If that is the case, that's obviously not going to work but how can i make it work? Attached is the current settings file for the controller. Not sure if that helps.

 

Sorry if this is a bit incoherent. I'm just so much out of ideas.
Thank you to anyone willing to give this a think.

EDIT: Mini update. Phone decided to connect randomly. Didnt change anything. Just decided to do that now. I took the opportunity to tell it the gateway was the edge router. Still connected. Maybe it is the DHCP settings then? Nevermind. It gets kicked as soon as i try to actually do something now. Again didn't change anything

 

EDIT 2: I had a friend help me and now the Edge router is out of the equation. Current setup is just the ISP modem acting as the DHCP server and router in general. Same Wifi issues persist. After more testing, widows devices seem especially affected by it. Setting a fixed IP and gateway does not improve the situation like on some of the android devices. I have also contacted UBNT support. Will update when i get a response.

Id your modem a router + modem combo unit? does it have a dhcp server? Does it do nat?

Does it connect to the network and  not get an ip? Does it just not connect?

Yep, it should do that + nas + firewall + dns normally.

What is the controller software running on? It just manages the aps, doesn't have anny trafffic pass througy it.

Yes its also a router but you cant turn the DHCP server off. It is very limited in settings. It never caused an issiue in the pas though.

Well im not really sure. It seems to not get an IP but it doesn't really tell me anything. It just kinda...bounces off? It tries and then it stops....Then it retries due to auto connect.

basic windows machine. i5, 16Gb Ram. Nothing special. Using it as a ghetto NAS and occasionally as a node to offload resource intensive tasks (lighting builds in UE4). Other than that it just sits there doing nothing until now where the controller software is running.

Then why did you get the edge router? Id just use that as a router, or buy a modem an don't have 2 routers.

Try setting a static ip then.

I got the EdgeRouter because of the QOS feature. The ISP router has no QOS settings whatsoever and with the internet speed i get, it was very much necessary.
The modeom & ER combo never caused a problem in the past so i doubt that is it. Im usre its something to do with the controller. I just dont know how to configure it correctly

Tried that on my phone. Static IP, explicitly set Fixed Gateway etc. Now it just jumps in and out.

More info

Have you tried running an older version of UniFi controller? I usually wait a few months before updating...sometimes things get screwy with it.

 

I'd also double check and make sure the APs all have unique static IP addresses, outside of the DHCP pool.

FIX!!!!

 

I contacted Support and they suggested 3 things:
"Make sure High-Performance Devices, Advanced features, and Auto-Optimize Network are disabled.

Settings > Wireless Networks > SSID > Advanced Options > High Performance Devices
Settings > Site > Auto-Optimize Network
Settings > Site > Advanced features"

 

I had everything already turned off except for "Auto-Optimize Network". That was it. i turned that off and suddenly everything worked like normal. I have no idea what that changed but it works now.

Hopefully this helps someone.
Thanks to everyone who made suggestions.
