Raspberry PI 3 B+ - WiFi help please

BuZz

@jonnykesh no - you don't decide what this forum is for thanks. It is a help forum also for RetroPie users.

jonnykesh

@buzz Okay with me.

jonnykesh

@buzz If you read OPs post you will see that he hasn't even input his SSID or password details or his file would not look like that.
So, he has set his Wifi country. Yet, has not bothered entering the actual details of his WiFi network.
Anyway.

BuZz

@jonnykesh That's not why he can't see his network. He has no details in there as no networks are showing up.

jonnykesh

@buzz that's exactly how it will look if he hasn't actually entered his WiFi details.
Anyway, as I said, I was trying to help.
Some people here seem to underestimate others.

@namyzark if you drop to a command prompt - what's the output of

apt-get install rfkill
iwconfig
rfkill list wlan

did you reboot after changing the wifi country via raspi-config btw ?

@jonnykesh As I stated in my original post, I've set the country code. You can see that in the copy of my config I posted. It's set to "US". It hasn't changed the fact that I can't scan for networks available.

I did have the SSID and password there. I deleted out the SSID & Password details so as not to share the details of my home network. I've put in my SSID & Password as well. It still has not connected to my WiFi.

I've copied the file from my working Pi 3, which I know connects to my wifi without issue.

Yes, I have rebooted. I've also taken the card out, checked the details, etc.

No, I don't have an ethernet cord plugged in.

@BuZz The results are as thus

rfkill is already the newest version (0.5-1).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

lo no wireless extensions
wlan IEEE 802.11. ESSID:off/any
Mode:Managed. Access Point: Not-Associated
Retry short limit:7. RTS the:off. Fragment the:off
Encryption key:off
Power Management:on

0: phy0: Wireless LAN

@namyzark said in Raspberry PI 3 B+ - WiFi help please:

Soft blocked: yes

Maybe that's the problem. Can you try running sudo rfkill unblock all and then re-run sudo rfkill list all ?
You should get at least 2 interfaces listed:

0: hci0: Bluetooth
	Soft blocked: no
	Hard blocked: no
1: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: no

@mitu That did the trick! I immediately got on the wifi and pulled an IP. Router confirms it's hooked up.

It is now on the network. I also rebooted just to ensure it would stay enabled. It did. Yay!!!

Thank you @mitu !!!

@namyzark Glad you got it working. I think @buzz nailed it with the diagnostics, I never would have thought rfkill would be enabled on a Pi, always thought this would be useful for laptops with dedicated wifi kill switch.

@mitu just had same problem and I know nothing thank you, never would have figured that out.
