No wlan0 interface detected

mitu

Did you set your the Country first ? I think it's required since Raspbian Stretch in order to use the Wi Fi.

Reignman

If I try to set Country I get : No wireless interface found 🤔

@Reignman sounds like a hardware issue. Do you get the same behaviour off a standard Raspbian install?

Reignman

@markyh444 Yes also of a fresh install. So that's what I'm afraid for that's it's hardware related. Although I don't understand why this was in the past also but back then I got it working again temporary ...

mitu

Can you run dmesg, taken after a cold boot, and post it on pastebin.com ?

Reignman

@mitu Yes but how do I save and export this info without network on my pi?

mitu

@Reignman Save it on the boot partition.

dmesg | sudo tee  /boot/dmesg.txt

Then take the sdcard out of the Pi and read the file from your PC.

Reignman

@mitu thank you, I'm gonna try this tomorrow morning. I'm not home now.

Posting log asap. 😁👌

I'm running into the same issue. Here's a dmesg from fresh boot.

@undrwater Please don't hijack a topic - start a new topic. You're running a Raspberry Pi2 - which doesn't have built in wifi btw. So you need a dongle.

@BuZz

Wow. Talk about assumptions. I would have sworn I was using the Pi 3. Thanks for the heads up!

@mitu Here is my dmesg

Dmesg

mitu

Doesn't seem to be anything Wi-Fi related (Bluetooth included). Maybe they're blocked ? Can you run

sudo rfkill list all

and post the output ? Does it detect any Wifi interfaces ?
Did you disable the Wifi/Bt via config.txt on your Pi ?

Reignman

@mitu I get no output from chat command. Havent changed anything in config.txt

With iwconfig I get :

lo no wireless extensions.

@undrwater Something is going on i need some type of help anyone.
I di all the steps to install retropie and then i downloaded all roms to usb plugged it in the raspberry pi 3 and when i go to restart emulation it tells me that “if this is the first time rebooting then i got something wrong?
I deleted all and re installed all same steps same outcome.
Right now at this moment i tried to change some audio it let me but as it went back to the main screen it froze ?
Any answers thank y

mitu

@Aztechomie64 Please open a separate topic and add the info asked in https://retropie.org.uk/forum/topic/3/read-this-first.

Reignman

@mitu Any ideas what I could do? Could it ba a hardware failure?

mitu

It's most likely a hardware failure.
Just to be sure there's nothing disabled, post your config.txt.

Reignman

@mitu Please see these links. My Pi is not easy accessible, Its built in in a cabinet.
