Wifi cannot connect - help please! Rasp + Amp2 - Hifiberry OS

Hi.

My Raspberry Pi  cannot connect to wifi.

I have a Raspberry Pi3B+ and a Hifiberry Amp 2 with Hifiberry OS running.

The initial start with ethernet cable was fine. I configured my spotify acount and I saved the credentials for my wifi network (but it continues working by ethernet) by web browser.

Then I turn it off and I unplug the ethernet cable and when I turn on the device, it cannot connect to wifi and I get the message "No Network connected, configure network using Wifi Setup" under the HifiberryOS Logo on the screen. The problem is that I can't find any netwok called "Hifiberry Setup" or connect through "http://HiFiBerry.local" as if it was a initialization.

What should I do?

Thanks!!

  Just put your Ethernet back on, reboot, connect via Ethernet and configure WiFi again.

  Hello. Thanks for the answer. I have already try that and I have the same problem again...I'm lost.
  I can configure the wifi with ethernet connected ( I can see "saved" next to my SSID) but not to change to wifi connection. And when I turn off and unplug ethernet, again...
  What should I do?
  Thanks again!

  Please enable SSH, connect via SSH and run the command
  
  ip a 
  
  after you configured and enabled WiFi (with Ethernet still connected).

  Hi!

  Thanks for the answer.

  How to enable ssh? I haven't found any docs on how to do it...

  I found this:

  https://www.hifiberry.com/docs/software/how-to-establish-a-ssh-connection-with-a-raspberry-pi/

  but I suppose that it's not working because I have to enable it first...

  Thanks

  Hello. Thanks again.

  When I use the command "ip a" I get this information:

  1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue qlen 1000

      link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

      link/ether b8:27:eb:3f:b6:75 brd ff:ff:ff:ff:ff:ff

  Is the information for wlan ok? 

  Sorry I'm lost.

  Thanks.

  This shows, that your WiFi isn't connected at all. 
  Check if your WiFi network name and credentials are really configured correctly in
  

  /etc/systemd/network/wireless.network

  My guess is that the network credentials are configured incorrectly.

  Hi. Thanks for your time.

  When I run the command:

  # /etc/systemd/network/wireless.network

  -bash: /etc/systemd/network/wireless.network: Permission denied

  Why permission denied? If my login is as root, there's should be no problem...

  Thx!

  PS: I still can see through web connection that Hifiberry interface show me that my Wlan is saved...

  Your WLAN might have been saved. However, if you credentials are wrong, the system won't be able to connect to it.
  The fiule is a text file, you can't execute it. To display its contents, type
  
  cat /etc/systemd/network/wireless.network

  Hello again.

  I tried to start the device (again) with no ethernet cable.

  I connected to the SSID Hifiberry_Setup_XXXXX as I can read in the wifi initial setup. I followed the first steps and when I go to connect to wifi, I can read that my SSID is already saved...and then I go to the screen that says: Applying network settings...with the logo turning and it never stops (I wait more than 15 min).

  And of course, later I connect to wifi at home and I can't find my device connected...

  Sorry to bother but I don't know what to do...

  Ah sorry, wrong file. 
  

  cat /etc/wpa_supplicant.conf 
  
  Check SSID and psk in this file

  Pau Sanchez April 29, 2020 14:23

  Hi. Thanks.

  Done. I get this:

  ctrl_interface=/var/run/wpa_supplicant

  country=ES

  ap_scan=1

   

   

  network={

  ssid="XXXXXXXX"

  psk="XXXXXXXX"

  }

  I change the info with XXXXX but the two were correct (My SSID and my PSW)

  This is ok. Unfortunately I can't say why the system doesn't connect to your WiFi network.

  Hi.

  Ok. Thanks anyway.

  I thing that may be related with the shity router provided to me by my ISP (Movistar). Everything is fine but when the moment comes, the router doesn't gives an IP Number. I am having now the same problem with Max2play. Everything is ok by ethernet but when I try to connect to WLAN, I see a message about that the connection is Activated but not configurated due to the lack of IP number so I suppose that there is something related to my ISP. 

  Thank you for your time.

  I have the same problem that I had with max2play and that I abandoned for this reason.

  Currently I have 3 raspberry with hat Amp2 the first one installed with the same iso image continues to work in wifi only.
  the 2 others worked in wifi for 10 days but since then, even a power off then a reboot doesn't work anymore, these 2 devices are not visible on the network
  I am desperate

  A priori I believe I have found the source of my worries.
  For the 2 raspberries with Amp2 which were problematic, one of them had an Ethernet IP in 192.160.1.61 and a WIFI IP in 192.160.1.62
  and the 2nd had a WIFI IP in 192.160.1.62
  Neither was connected via Ethernet, but when restarting after a power cut, AC visibly blocked both.
  I let them run like this with the HifiberryOs and I hope everything is resolved ....

  My 2 rpi3 and amp2 are always unstable they work for a while then disappear one or the other without warning, then can come back for no visible reason. Maybe a conflict with airplay, blutooth or a cambridge streamer.
  Currently one of them does not respond to the ping but it is visible in the airplay and if I cut the blutooth, it disappears from the airplay in spotify on Iphone
