I just got my pi3 yesterday and out of the box wifi was working with retropie. I performed some updates and somewhere along the line the wlan0/wifi stopped working. Because it did work I do not believe there is any issues with my router/modem.
When I perform iwconfig it lists lo and eth0 but not wlan0. I tried flashing the sd card with retropie 3.8.1 and 4.0 release candidate and both exhibited the same behavior. I then tried NOOB (raspberian) and this also does the same thing. Where the network icon is on the upper right corner it says "No wireless interfaces found".
This transcends operating systems it seems, so it feels like a bios or something. Like I said I just got this, and am new to pi's.
- sudo apt-get update
- sudo apt-get dist-upgrade
- sudo apt-get upgrade
- sudo rpi-update
- modifying /etc/network/interfaces (i've restored it to default)
- lsusb (lists mouse/keyboard/ethernet/standard microsystesms/linux foundation 2.0 root hub) but not wireless
- sudo iwlist wlan0 scan (says "Interface doesnt support scanning")
I see a lot of similar issues out there, but they seem to be with wifi dongles. This is a pi 3 so that isn't the issue.
Any help would be GREATLY appreciated.
I tried: No wireless firmware found from a Wi-PI on a Raspberry Pi? without any luck.
I've found 2 other threads at raspberrypi.org that describe the same behavior. Both have suggestions that I've tried, but neither have answers or were able to solve my issue. I've posted in both in hopes to resurrect those threads.
Here is how I flashed my SD cards. I have a 128gb sd card so I followed these instructions https://www.raspberrypi.org/documentation/installation/sdxc_formatting.md:
For NOOBS - download zip, extract, use SD Formatter to get rid of partitions, use guiformat to get into fat32, copy extracted NOOBS files over.
For retropie, formatting card was the same (SD Formatter, guiformat), but then I use win32diskimager to place the images onto the sd card. These are two fresh images from the download section of retropie. Versions 3.8.1 and 4.0 rc1. I used the exact same image of 3.8.1 to flash the first time as I did later times. I did however, try to download another copy, which didnt work - same behavior.
