Wifi HotSpot - Thethering ethernet to wifi

I want to create a WiFi network based on the ethernet connection
I’ve got the latest version of osmc on my Raspberry Pi 3B that is connected to Internet via Ethernet cable
I first went Settings → My OSMC → Network → Tethering → Enable
then looked up also by command line:
image
and I cannot connect to this network
there’s no log anywhere than anything went wrong
the connection just drops immediatly on mobile and tries reconnect and drops again
What should I do to grab some more info of what could go wrong?

You could check ifconfig. If your wired network is 192.168.0.x, the tether should be 192.168.1.x and vice versa.

any ideas what I co do?

What you tried connecting on another device?

on Windows:

Do you have another OSMC device you can try connecting from?

Unfortunately, I don’t

Just tried tethering (ethernet to wifi) on my rpi 3b+ and got an ip with my android smart phone immediately.
What you see in /var/lib/conmann? If there are folders starting with wifi… remove them.

There was one wifi saved there but I removed it now
but the issue remains

I’d be happy to set up some loggings to know what’s the deal here but I don’t event know where to start

I’d read somewhere about wpa_supplicant but I’m not sure if it’s used at all, since theres’ no config file:

Well, first difference I’ve noticed: You have a p2p technology mentioned, here I don’t have that enabled/visible.

Regarding logging: You could change /usr/bin/start-network and give every call of connmand the option -d in addition which give some debug info.

A dmesg -w lets you monitor the kernel messages when your device tries to connect to the tether wifi.

I’ve added debug flags to some places:


and the kernel messages output is here but doesn’t seem to be changing while connecting

Sorry, my fault: Instead of dmesg -w use sudo journalctl -f

I cannot see connman here, somethinh is off

You can also increase the debug logging level of the wpa_supplicant by specifiying -d or the -dd in the call of wpa_supplicant at /lib/systemd/system/wpa_supplicant.service. Invoke a sudo systemctl deamon-reload followed by a sudo reboot, afterwards.

Only help I can give is how it looks like on my rpi 3B+ (it has another wifi chip than your rpi3 B) with active -d options for connmand and wpa_supplicant:

Have you rebooted the rpi after your change?

I rebooted now after adding the debug flag to that service you mentioned
So I gather some logs, there’s plenty of them.
I’d analyze them later today but maybe you could take a look if you see something out of ordinary

I cannot paste them since they’re too big and also cannot include .txt file so here’s the pastebin: Dec 21 06:26:07 osmc sudo[662]: osmc : TTY=pts/0 ; PWD=/home/osmc ; USER=roo - Pastebin.com

Like you I have not seen these logs before but I’ll have a short look at it later. Don’t count on me. Perhaps, others can shed some light what’s going wrong with your rpi.

Here is where it starts to behave different/starts failing in your logs compared to mine:

Dec 21 06:26:23 osmc wpa_supplicant[209]: hostapd_logger: STA 8c:f5:a3:99:f6:f8 - sending 3/4 msg of 4-Way Handshake

Dec 21 06:26:23 osmc wpa_supplicant[209]: WPA: Use EAPOL-Key timeout of 1000 ms (retry counter 2)
Dec 21 06:26:24 osmc wpa_supplicant[209]: hostapd_logger: STA 8c:f5:a3:99:f6:f8 - EAPOL-Key timeout

During the WPA authentication (especially during the third phase of the 4-way handshake) there is no more response from the wifi client (timeout 1000 ms). There are 5 retries of this phase, then the code gives up (believing the log entries).
Whether something goes wrong on the client side (WPA and WPA2 enabled? WPA implementation buggy?) or the rpi (some bug in wpa_supplicant, wifi driver or wifi firmware), I cannot say.

What mobile device is it?

Hey
sorry for late reply
I changed WiFi password just to see if that changes anything, but sadly not
Mobile device is Samsung Galaxy S7, but I also use a laptop to connect, that’s a log from laptop attempt: Dec 21 22:26:44 osmc sudo[1898]: osmc : TTY=pts/0 ; PWD=/home/osmc ; USER=ro - Pastebin.com

Maybe my raspberry is faulty
Maybe for another try I’ll use some other sdcard with something else installed like raspbian or whatever and see the thethering there, just to exclude or confirm hardware issue
