Unifi Cloud Key Gen2 Plus

Migration

Cloud Key 1

Migrating our SDN network settings and historical data from the original Cloud Key to the Cloud Key Gen2 was extraordinarily simple:

Download a backup from your original Cloud Key. (In UniFi Controller, go to Settings > Maintenance > Backup. Click Download Backup).
Safely shut down your original Cloud Key. (Settings > Maintenance > Cloud Key Operations. Click the Shut Down Cloud Key button.)
After following the initial setup of your UniFi Cloud Key G2, start the setup wizard.
Select restore from a previous backup. Then upload the backup from your original Cloud Key.

Unifi Best Channel Selection Multiple UAPs

Try to use different channels on each UAP, I recommend the following Radio Settings.

Devices > UAP > Config > Radios

2.4 GHz
Channel width: HT20
Chanel: 1/6/11 | Choose one of these channels, a RF scan will help you choose the most clean one.
Transmit Power: Low ( Medium )

5GHz
Channel width: VHT40 | Optional VHT80/VHT160 might decrease wireless stability
Chanel: 36/44 | Optional (149/157) Choose one of these channels, a RF scan will help you choose the most clean one. Avoid using DFS 
Channels
Transmit Power: Medium ( High )

Unifi Multiple Super Admins

Setup First Super Admin Account First, setup the controller with the first super admin account like normal. Usually, the first account that you create when setting it up is the original super admin.

Next, enable Cloud Access to that account.

Add Second (or more) Admin Accounts

Next, add the second (and third, fourth, etc. if applicable) admin account.

Login to New Admin Account(s) and Enable Cloud Access

Login to the controller with the new admin account, navigate to Cloud Access, enable it and enter the username for the Cloud Access account. Note that this username will be different than the username used for the original super admin account.

Repeat this process for additional admins.

Change Admin(s) to Super Admin(s)

Log back in to the controller with the original super admin account, then change the admin account(s) to super admin using the "Role" drop-down menu.

Now you can have multiple super admin accounts each with their own Cloud Access accounts.

Why do this? Why not just have one super admin account and multiple admin accounts?

I found that there isn't much difference between the two account types, other than that admins cannot adopt devices, setup new sites, and don't have access to the Maintenance or Auto Backup menu options on the left navigation pane. For us, we wanted all three administrators to have those functions.

Unifi Switch 24

Reboot

With a paper clip, depress the Reset button until you feel it click. Hold for 1 second, then let go.

Reset

Correct Method

Resetting a Unifi Switch

Power off the device: Just unplug the power cable
Forget the device in the controller: Open your controller, select the device, click settings and scroll down to forget (only if applicable)
Unplug all network cables: A PoE enabled switch will not factory reset when it is providing PoE to connected devices
Plug the power back in and let the device boot, do NOT press the reset button yet!
Wait for the device to fully boot, the led will turn dark blue (or stay white if it wasn’t adopted before, approximately 5 minutes max)
Press the reset button for 5 seconds: Use a paperclip to press the button for 5 seconds to initiate the factory reset
When the reset is completed the led will turn pale blue. You can now adopt the switch in the controller

https://lazyadmin.nl/home-network/reset-unifi-switch/

Normal Method

With a paper clip, depress the Reset button until you feel it click. Hold for 10 seconds, then let go.

Hail Mary Method

Unplug the power cable.
With a paper clip, depress the Reset button until you feel it click. Hold firm.
Plug in power, while continuing to hold paper clip firm.
Wait until the LED begins flashing in a repeating pattern: Off Blue White.
Release paper clip reset.
Unplug the power cable. Wait 5 seconds; say Hail Mary, and plug power cable back in.

EdgeRouterX with DrayTek Vigor 130

The Vigor 130 is a pre-configured VDSL2 / ADSL2+ modem that takes a VDSL2 or ADSL2+ connection and performs full pass-through / bridge to Ethernet presentation, which can then be used by a device such as a router to connect directly to the internet. For the official specification of the Vigor130, refer to this link.

The Vigor 130 does not store any Internet usernames or passwords itself - those go into your router, or whatever you are connecting to the Vigor 130.

The settings on the Vigor 130 are correct for most UK lines out of the box, so in most cases it should only be necessary to configure the router that it is connected to.

The DrayTek Vigor 130 modem has a web interface available on http://192.168.2.1 (username of "admin" and password of "admin" by default).

This can be used to check ADSL / VDSL diagnostic information or re-configure the modem to bridge a DHCP / Static IP connection if required.

Some routers such as the Vigor 2860 and Vigor 2925 can display the Vigor 130's VDSL statistics automatically in the router's web interface, which can be found in the [Online Status] > [Physical Connection] page of the router's web interface.

Default Vigor 130 settings:

Configured to pass through a PPPoE connection
VDSL2 VLAN Tag is set to 101
ADSL VPI/VCI is set to 0/38 for PPPoA connections, 0/101 for MPoA connections

The above are the correct settings for the majority of UK ISPs so you do not need to change any settings on your Vigor 130 or access its web interface. Go straight to your router setup. Some exceptions are Kingston/Karoo, O2 and Vodafone Ireland - each of those has their own settings, so check with them for their latest, specifically for your DSL type (ADSL or VDSL).

Setup Procedure:

Connect the RJ-11 port (marked 'DSL') on the Vigor 130 to the VDSL or ADSL line.
Connect the RJ-45 Ethernet port on the Vigor 130 to the WAN ethernet port of your router (or PC).
Configure the WAN interface on your router to use PPPoE and enter the username and password details for the internet connection.

HOWTO: Hardware Offloading

UPDATE: Yeah, jury is still out on this... on the ER-X it does not seem to make any difference and if you're using Smart Queue Management QoS then it won't work on that anyway!

Offloading is used to execute functions of the router using the hardware directly, rather than a process of software functions to greatly increase performance.

Instructions

Latest Version: 1.10.11
Previous Version: 1.10.10

Note: The ER-X/ER-X-SFP/EP-R6 has more limited storage, and in some cases upgrade may fail due to not enough space. If this happens, remove the old backup image first (using "delete system image" command below) before doing upgrade. The system will always have at least 2 images so you are alright to remove the older one.

Command Line

show version
show system image
delete system image

Edit Config Manually

You can edit the config file in the vi or nano editors ...

sudo vi /config/config.boot

... then check the file with these commands (in this example I have changed just the system 'host-name') ...

ubnt@erx:~# configure
[edit]
root@erx# load
Loading configuration from '/config/config.boot'...
Load complete.  Use 'commit' to make changes active.

... then reboot to apply the changes ...

ubnt@erx:~# reboot

Change Config Editing Directly Safe Boot

Save a couple of copies of the current config.boot file with different names...

configure
save config.boot-old
save config.boot-new
exit

Then, edit the file config.boot-new and save it...

vi /config/config.boot-new    (press I to come out of view mode, then press ESC then press :wq to save)

Once finished...

configure
load config.boot-new
commit-confirm 10

If all is ok, issue confirm and save within 10 mins, otherwise, the router will reboot with the previous config.

Firewall Regions Explanation

WAN_IN is from the internet, through the router, and onward to your LAN. In very general terms, you want to drop 90% of this mess - it's script kiddies, port scans, nigerian princes, and anyone else you don't want able to head through your router. Obviously, you're gonna want to allow ports 80, 443, 25, and others if you're running those types of services. If you haven't got any idea what I'm talking about with those three ports, better to not open them.

WAN_LOCAL is from the internet to your router, with no intention of going farther. Best to just drop everything on this interface -- unless, for example it's a router at a remote site, and you've got a static at your main site, so you allow traffic from 10.10.x.y/28 (note, I'm using private address space as an example, real world would depend on your ISP).

LAN_IN is everything inbound to the router from your LAN (e.g. 192.168.1.0/24) that's destined for somewhere else (WAN, other LAN such as 192.168.2.0/24). In a SMB, or SOHO setup, this is probably explicitly permissive. In an enterprise setting, this may or may not be permissive (e.g. blocking all outgoing traffic except for SFTP on a non-standard port).

LAN_LOCAL is everything inbound to the router from your LAN destined for the router. Again, unless you're doing enterprise routing, this is probably fairly open - although good SMB setups with guest networks may block the guest network range.

Command Auto Completion

You can press the ? key to find the top-level commands, then type that command and ? again to find the options for that top-level command.

?
show ?
show version
show interfaces
show interfaces ?
show interfaces ethernet

You can also use the keyboard Tab button to complete the options.

Show Configuration

There are 2 ways to show the current configuration - in a tree or in commands:-

show configuration all
show configuration commands

If you use the 'commands' option, you can then grep or 'match' the output to limit results.

show configuration commands | match system

Edit Configuration

You have to enter 'edit' mode first, and it will show you after every command that you are in this 'edit' mode with a separate line just above the prompt showing [edit]...

configure

When you have finished your command changes, you can show your changes, to check...

compare

To make the changes active, you have to save them...

commit

Then, come out of configure mode...

Unifi Security Gateway USG

Unifi Cloud Key

UniFi - Accounts and Passwords for Controller, Cloud Key, and Other Devices

EdgeRouter or USG Virgin Media Cable SuperHub3

If so as you say WAN to USG cable in bottom socket.
Set USG to get a DHCP address on the WAN side.
No other settings required to be input.
Delete or disable your current BT PPPoE settings though if they are still in USG or ER-X.
After setting up USG you will need to reboot the Virgin hub.

Superhub3 Modem Mode Ubiquiti Amplifi

as legacy1 turn on modem mode on the hub.. turn off both hub and the Amplifi Router, making sure got ethernet cable attached nearest the coax cable going into the WAN port of the Amplifi Router.. turn on the hub give it a few minutes then the Amplifi Router..

this would mean the Amplifi Router deals with all DHCP/NAT security etc etc.. just means only 1 port will be active on the hub.

Ubiquiti and Virgin Media Cable

Set the Virgin Superhub to run in modem only mode. This stops it being a router and makes it like the oldVirgin/Telewest/NTL cable modem from Scientific Atlanta etc.
Connect alternative router to the bottom RJ-45 ethernet socket only on the Superhub.
When you have set up new router don't forget to reboot Virgin Superhub.

How do I put my Virgin Media hub into modem mode?

EdgeRouter VDSL

ECI Openreach modem for FTTC

HOWTO: POST INSTALLATION ACTIONS:

Define The Java Version:

Edit the following file, adding the path to Java 8 installation:

sudo nano /etc/init.d/unifi

JAVA_HOME= # Edit this line to match that shown below

JAVA_HOME=/usr/lib/jvm/java-8-oracle

Open The Required Firewall Ports:

Open ports on the server's firewall (in this example UFW):

For internal connection:

sudo ufw allow from 192.168.0.0/24 to any port 8080 proto tcp
sudo ufw allow from 192.168.0.0/24 to any port 8081 proto tcp
sudo ufw allow from 192.168.0.0/24 to any port 8443 proto tcp
sudo ufw allow from 192.168.0.0/24 to any port 8843 proto tcp
sudo ufw allow from 192.168.0.0/24 to any port 8880 proto tcp
sudo ufw allow from 192.168.0.0/24 to any port 27117 proto tcp
sudo ufw allow from 192.168.0.0/24 to any port 3478 proto udp

Details of the ports required by Unifi can be found here.

Port 3478 UDP relates to STUN server usage so if you are not using VOIP hardware this port is not needed.

If your server already uses any of the ports listed above how to change those used by Unifi can be found here.

The file to alter to use different ports can be found in the following location:

/usr/lib/unifi/data/system.properties

Lost Password

If you need to reset your UniFi password at HostiFi, you should use the password reset link from your controller. This article is for resetting passwords on non-HostiFi controllers, to help users migrate when they have lost their old credentials.

Find the "name" of the admin you want to reset with this command:

mongo --port 27117 ace --eval "db.admin.find().forEach(printjson);"

Replace <username> with the admin account name you found above:

mongo --port 27117 ace --eval 'db.admin.update( { "name" : "<username>" }, { $set : { "x_shadow" : "$6$ybLXKYjTNj9vv$dgGRjoXYFkw33OFZtBsp1flbCpoFQR7ac8O0FrZixHG.sw2AQmA5PuUbQC/e5.Zu.f7pGuF7qBKAfT/JRZFk8/" } } )'

Now you can log in as that admin with the password password.

NOTES

Need to add a second virtual disk for the repair.

repairDatabase requires free disk space equal to the size of your current data set plus 2 gigabytes. If the volume that holds dbpath lacks sufficient space, you can mount a separate volume and use that for the repair. When mounting a separate volume for repairDatabase you must run repairDatabase from the command line and use the --repairpath switch to specify the folder in which to store temporary repair files. For example:

--repairpath <path>

Default: A _tmp_repairDatabase_<num> directory under the dbPath. Specifies a working directory that MongoDB will use during the --repair operation. When --repair completes, the --repairpath directory is empty, and dbPath contains the repaired files. The --repairpath must be within the dbPath. You can specify a symlink to --repairpath to use a path on a different file system.

mongod --repair --repairpath /opt/vol2/data

NEW

sudo -i
service unifi stop

If that does not work, then you will have to stop unifi, uninstall, clear db folder (/usr/lib/unifi/data/db), install same version, restore from backup.

sudo apt-get remove unifi
sudo apt-get autoremove (to nuke mongodb stuff)
mv /var/lib/unifi /var/lib/unifi.bak (later to be deleted)
sudo apt-get install unifi

Error: MongoDB Journal Files Eating Disc Space.

A. MONGO DB PRUNE OLD DATA FIX

wget "https://help.ubnt.com/hc/article_attachments/115024095828/mongo_prune_js.js"
sudo mongo --port 27117 < mongo_prune_js.js

Official Unifi Page

B. SMALL FILES FIX

stop system wide mongodb from starting
edit system.properties file for smallfiles parameter
start unifi

sudo nano /etc/init/mongodb.conf
     ENABLE_MONGODB="no"
sudo nano /usr/lib/unifi/data/system.properties
     unifi.db.extraargs=--smallfiles
sudo update-rc.d -f mongodb remove
sudo service unifi start
