WiFi - need more signal.

[Dr_Ju_ju]

this 'should' work:

sudo dpkg --remove --force-remove-reinstreq (package name)

sudo apt-get remove (package name)

sudo apt-get autoremove

sudo apt-get autoclean

then reinstall

sudo apt-get install (package name)

 

[Gina]

Thank you - I'll try that

[Gina]

The removal and clean up seemed to work alright - no errors.  Then I rebooted and tried installing unifi but that gave errors.

[Gina]

Gonna get a cuppa

[Dr_Ju_ju]

I know it says its only a suggestion, but I'd install all pre-requisites before the main install, especially the java virtual server.

[Gina]

Did the removes and clean again and installed java-virtual-machine which proceeded without error

[Gina]

Tried installing unifi and when i asked "Do you have a backup" I answered Yes this time - I answered No last time.  It all went through with no errors   Not to see if it's available from the Menu...

[Gina]

Not ATM maybe needs a restart...

[Dr_Ju_ju]

isn't it just a web\http interface ??  so you would need a browser to see it, like the Indi web server....

[Dave_D]

just a thought... have you considered installing a yagi in your obsy? 

[Gina]

Nothing in the menu but it is listed in synaptic.

Quote

Ubiquiti UniFi server is a centralized management system for UniFi suite of devices.
After the UniFi server is installed, the UniFi controller can be accessed on any
web browser. The UniFi controller allows the operator to instantly provision thousands
of UniFi devices, map out network topology, quickly manage system traffic, and further
provision individual UniFi devices.

So it seems that's a "yes".  But how to access it.  In the instructions for Windows and Mac it says to access it from the menu so I assumed it was the same for Linux.  Anyway, it seems to be properly installed now   One step forward

I want decent WiFi in the house!  Which I haven't got.

[Dr_Ju_ju]

The fun thing will be finding the port it's listening on, but when found http://127.0.0.1:(port number) and you should be good to go....

The Windows\Mac interfaces are probably just hyper-links

[Gina]

I have the user guide and it says this

Quote

The UniFi Controller software has a browser-based

interface for easy configuration and management.

To access the interface, perform the following steps:

1.

Launch the UniFi Controller application if hasn’t already

been started.

• Mac users:

Go > Applications > UniFi

• Windows users:

Start > All Programs >

Ubiquiti UniFi

.

2.

The UniFi login screen will appear. Enter the admin

name and password in the appropriate fields and

click

Login

.

I haven't yet found any reference to port number.

[Dr_Ju_ju]

try running:

nmap 127.0.0.1

it should come back with all the services & ports....

or failing that 

ps -ef

ps -ef | grep (service name) If it shows up

 

& I've just found from here (https://community.ubnt.com/t5/UniFi-Wireless/new-install-of-Unifi-Controller-5-5-20-not-working-on-Linux-Mint/td-p/2042367) that opening a browser to:

http://localhost:8443 should work.

[Gina]

Unfortunately it doesn't

[Dr_Ju_ju]

back to basics....

try:

ping localhost - should respond with local ip address and or 127.0.0.1, if not, check net settings

telnet 127.0.0.1 8443 -  if there is a response the web interface is running, if not you'll need to check the running services especially java tomcat (I believe that is what is used, but maybe just apache) \ mongodb 

 

 

 

[Stub Mandrel]

Thank you for this thread.

I shall point people at it when they ask why I don't use Linux.

[Gina]

Followed the link though and it said https://localhost:8443 which does something.

[Dr_Ju_ju]

Then according to the link I posted, if the web server is up, but getting garbage, the web server is unable to use the mongodb, whether its running, or missing permissions. getting closer....

[Gina]

It's working   Sort of...

[Gina]

This doesn't seem right - the thing is connected and it's showing a light - sort of pale blue, may be meant to be white.

[Gina]

It's a white light - I tried disconnecting and re-connecting and it flashed whit a few times then blue a few times then steady white.

[Gina]

Ah a device has appeared
