Connecting with wifi - LuNik700 - 11-13-2019
Hi everybody,
my name is Ludger and I'm having problems to integrated one of my moOde-players into my network via wifi.
I use 2 Raspberry Pi with moOde - one is working perfect, the other isn't.
Both a based on a Raspberry Pi 2 Modell B V1.1, with a MamboBerry LS I2S audio device and an EdiMax Wifi stick. And both are using an SD-Card with the lastest moOde release 6.3. So I would say the setup is identical.
The problem seems to be that scanning for an SSID does not return a result (no matter of distance - the Raspberry is right beside the router!). Entering the SSID manually doesn't help.
Therefore the RasPi falls into AP mode. If I then connect to moOde using 172.24.1.1, I can access moOde but again I not able to change settings for my wifi network.
The funny thing is that when I use an SD card with an old moOde Release 3.8.4. everything works fine out of the box. So it doesn't seem to be a hardware issue!?!
Here is a a snippet of moodeutl -l ...
20191113 110500 worker: wlan0 trying SSID (LuNik700-2)
20191113 110500 worker: wlan0 wait 0 for IP address
20191113 110503 worker: wlan0 wait 1 for IP address
20191113 110507 worker: wlan0 wait 2 for IP address
20191113 110510 worker: wlan0 wait 3 for IP address
20191113 110513 worker: wlan0 wait 4 for IP address
20191113 110516 worker: wlan0 no IP addr for SSID (LuNik700-2)
20191113 110516 worker: wlan0 AP mode started
20191113 110549 worker: wlan0 wait 0 for IP address
20191113 110553 worker: wlan0 wait 1 for IP address
20191113 110556 worker: wlan0 (172.24.1.1)
I not very experienced in Raspbian so I havn't got a clue where to look at next.
Please can somebody give me a hint. Thanks!
Best regards
Ludger

Check that the wpa_supplicant file is identical on both Pi's.

Thanks Tim!
Before reading your reply I kept on trying and suddenly it worked! No idea why!?!?!
I checked the wpa_supplicant files on both RasPis and right now they are identical. The password of my wifi includes a '*' and a '#'.
What I don't understand is why scanning for a wifi network did not work?!?! In fact I've got two of them but until at last I succeeded neither of them was found?!?!?!. Is this another bug or is this corresponding to the one mentioned in the post above?
Thanks for your quick and helpful reply!!!!
Best regards
Ludger

Prolly not a bug in the scan. It runs the command below twice to improve the results. Give it a try.
Code:
sudo iwlist wlan0 scan | grep ESSID | sed 's/ESSID://; s/\"//g'
sudo iwlist wlan0 scan | grep ESSID | sed 's/ESSID://; s/\"//g'-Tim

As the wifi failed again after a reboot I tried out the cmd above ...
pi@SysL-RasPi2:~ $ sudo iwlist wlan0 scan | grep ESSID | sed 's/ESSID://; s/\"//g'
wlan0 Interface doesn't support scanning : Operation not supported
and I think that's what moodeutl -l shows:

20191113 173931 worker: wlan0 trying SSID (LuNik700-2)

20191113 174657 worker: wlan0 (172.24.1.1)
By the way the wpa_supplicant filesare still identical on both Pi's....
pi@SysL-RasPi2:~ $ sudo cat /etc/wpa_supplicant/wpa_supplicant.conf

Literally right beside? That may be so close you're overloading the radio receiver in either or both devices. Try separating them a (meter | 3 feet) or so.

Good idea ... but didn't work. Before I tried it the Pi was about a meter away from the router ...

Might be worth swapping WiFi dongles to see if the problem persists or moves to the other Pi.
