Unable to configure wifi interface on raspberry pi 3 B+

rishav_09 · July 21, 2018, 7:35pm

via wifi it’s not connectingto network at all. i checked into router’s DHCP client list, but hassio isn’t there.
BTW is there anyother way to configure wifi through ssh ?

Please post:

the full name and path of the network setup file
the precise contents of the file (you probably don’t want to show us your ssid or network password.)

You can check how to from here for hassio

github.com

home-assistant/operating-system/blob/dev/Documentation/network.md

# Network

HassOS uses NetworkManager to control the host network.

## Configure network

Only a manual configuration using NetworkManager connection files is supported. Without a configuration file, the device will use DHCP by default. These network connection files can be placed on a USB drive and imported to the host as described in [Configuration][configuration-usb].

## Configuration examples

You can read the [NetworkManager manual][nm-manual] or find many configuration examples across the internet. Keep in mind that the system is read-only. If you don't want the IP address to change on every boot, you should modify the UUID property to a generic [UUID4][uuid]. Inside the `\CONFIG\network\` directory on the USB drive or SD card, create a file called `my-network` and add the appropriate contents below:

### Default

A preinstalled connection profile is provided by default:

```ini
[connection]
id=my-network
uuid=f62bf7c2-e565-49ff-bbfc-a4cf791e6add

This file has been truncated. show original

rishav_09 · July 22, 2018, 4:53am

so here is content of file:

[connection]
id=HassOS default
uuid=f62bf7c2-e565-49ff-bbfc-a4cf791e6add
type=802-3-ethernet

[ipv4]

[ipv6]

and path to the file is
my-network is saved WITHOUT any file extension.

The instruction page Getting started - Home Assistant says the file should be called network/hassos-wifi, although I am unsure if the precise name matters.

you are missing the opening [ on the connection line.

Also, is there a reason you want both wired and wireless?

rishav_09 · July 22, 2018, 8:12am

okay … that worked. and the file must be named as network/hassos-wifi.
lucky being able to configure wifi & ethernet with static ip’s

rambutan2000 · November 6, 2018, 5:30am

I’m having the same issue, have more things to try, but for clarity is this help out of date:

WiFi and Static IP setup only: Format a USB-Stick with name CONFIG , create a folder named network and within that folder a file named my-network . Copy one of the examples to the my-network file.

It’s unclear if ‘my-network’ is to be taken literally or replaced with something.

nickrout · November 6, 2018, 5:31am

Literally.

JuanM · November 6, 2018, 5:43am

The USB drive, name it CONFIG. Then create a folder name network and then create a file named system-connections. Inside the file, enter the following:

[connection]
id=hassos-network
uuid=YOUR_UUID_NUMBER
type=802-11-wireless

[802-11-wireless]
mode=infrastructure
ssid=YOUR_WIFI_NAME

[802-11-wireless-security]
auth-alg=open
key-mgmt=wpa-psk
psk=YOUR_WIFI_PASSWORD

[ipv4]
method=auto

[ipv6]
addr-gen-mode=stable-privacy
method=auto

You can find a full guide for Hassio here

rambutan2000 · November 6, 2018, 6:00am

Thanks JuanM! that did the trick

mitchlowther · December 10, 2018, 10:30am

I’m having the same issue as the original poster…

@JuanM
Thanks for your tutorial, it has given the most accurate directions so far so just wanted to start by saying thank you.
I’m having difficulty getting the pi to connect to wifi. All i’ve done so far is follow your tutorial, however the only part i’m not 100% sure of is the file type of the ‘system-connections’ file. i’m using a .txt file?

Once I boot the Pi I can see the ACT Led flashing, however I get an error message when i go to http://hassio.local:8123/
“DNS_PROBE_FINISHED_NXDOMAIN”.
After trying again and again the following message appears:
“ERR_NAME_NOT_RESOLVED”
The only difference to your tutorial is that i’m using the 32Bit image.

I’ve no idea where to go from here, someone please help

nickrout · December 10, 2018, 6:29pm

The file has no extension. A .txt extension is a windows thing, hassio runs linux.

mitchlowther · December 11, 2018, 12:38am

Thanks for that Nick, I’ll give it a go.

For anyone reading this, to save a ‘file’ in something like notepad, google says to put the file name into quotation Mark’s when saving and done add an extension.
I’ll try this and update if it has worked
Thank you!

mitchlowther · December 11, 2018, 6:54am

Well the file has worked and my router can see my raspberry but i can’t access it through it’s IP address or via 'http://hassio.local:8123/.
I’m using a raspberry pi 3 B+ and have used the latest hassIO image from ‘https://www.home-assistant.io/hassio/installation/’ however I still can’t manage to see anything on my browser.
Any help appreciated or best off to move to hassbian?

**SOLVED
For anyone having similar issues, I logged into my router to find my devices IP address. Once found you need to put this into the URL bar FOLLOWED by the port number 8123 - so; http://192.168.1.1:8123

nickrout · December 11, 2018, 7:32am

Yes the port number comes after the ip address/hostname.

Zodiarc · December 15, 2018, 8:47pm

I have the same problem. Followed the tutorial by JuanM, Followed the hassio setup instructions, renamed the file to any possible name I could find on the internet and no luck. Hassio just won´t connect to WIFI. I first thought it may be because I´m using a RPi2 with a dongle so I got a RPi3B+. No change. Im extremely frustrated because “advertising” something as an easy to setup headless system and not providing a straightforward way to the most basic thing in the world (connect to WIFI) is just sad. Is there something that changed and was not added to the documentation? I´m seriously considering using something else than HA just because of the WIFI issue.

nickrout · December 15, 2018, 8:53pm

Well you could use hassbian and avoid this method of setting up wifi entirely, or used wired ethernet.

Or you could post your file and exactly what error messages you are getting.

Zodiarc · December 15, 2018, 9:06pm

The file content was exactly as provided in the thread (but with my own UUID, SSID and wifi password of course). After connecting to a tv via HDMI i couldn´t find any error messages but thanks to WIFI definitions on HASSIO I was able to setup wifi. This is of course nowhere near to a headless setup.

nickrout · December 15, 2018, 9:11pm

No its annoying to have to plugin like that. Still, done once and now you’re up and running .

KePeSWE · March 17, 2019, 12:25pm

Hi

I have followed Juans guide to the letter, but my Pi stil dont connect to the wifi nor wired. Enclosed pictures about my error on the tv.

Here my system-connections file withour extensions:
[connection]
id=hassos-network
uuid=27c2ab96-4bb7-4a43-9ec5-c975dbb0b0f1
type=802-11-wireless

[802-11-wireless]
mode=infrastructure
ssid=MY_SSID

Uncomment below if your SSID is not broadcasted

#hidden=true

[802-11-wireless-security]
auth-alg=open
key-mgmt=wpa-psk
psk=MY_PWD

[ipv4]
method=auto

[ipv6]
addr-gen-mode=stable-privacy
method=auto
