Change wifi problem at Rasbian

[leejaeuk]

hello, admin.
i have problem about re-connection wifi. (Current status connect wifi)
First execution work very well ( sudo wifi-connect and setup my mobile phone from captive portal)

After Wifi connection, i want to change another wifi. then i execute same command( sudo wifi-connect) but existing wifi is disconneted with this error printed like this.

"Error : Cannot start HTTP server on '192.168.42.1:80':address not available
"dnsmasq : unknown interface wlan0"

i check the dnsmasq status but it activated well.

give me some help.
thank you.

Hi @leejaeuk, I did not had a chance to check this earlier. Just tried that out and it works well for me here. What particular RPi device type are you using? And also which Raspbian version are you running it on?

@majorz
Hi, I'm using raspberry pi 3B+, 3B and zero.
and using raspbian OS version is contemporary version.

relate this problem..
i found a kind of solution.

first, i delete wifi connected information file that was wifi name, when i connected. [ cd /etc/NetworkServicemanager/system..(i don'y remember exactly name of directory)]

and i execute ' sudo systemctl stop dnsmasq '

then, i can success changed to another wifi.

without this process( i just executed 'wifi-connect'), wifi change have problem.

I am glad that you found a solution for this. So this is an issue with administering the Raspbian installation and not directly connected to WiFi Connect, so I am closing this issue as successfully resolved.

Was a better work around ever found for this issue?

./wifi-connect --portal-listening-port 45454

@andrewjaykeller it looks like the wifi driver is crashing or something similar - first it is not able to detect networks, and then it is not reachable by dnsmasq. Is this for the Artik board from the previous ticket? I looked that up and I noticed that it uses the proprietary Marvell WiFi driver, which is not being kept up to date in the Samsung Linux kernel tree. What is more worrying is that there are not any kernel updates from a long time ago: https://github.com/SamsungARTIK/linux-artik.

What I really suggest is trying to run WiFi Connect on different OS systems - the one that Samsung Artik officially supports (I think they had Ubuntu download), and also latest Resin OS. If you get it working on Ubuntu, but not on balenaOS, then it should not be hard for my team mates to fix this. If it is not working on the official Artik distro, maybe you need to take a look at a different board, as their kernel tree looks a bit abandoned.

@alexcastillo see above

@majorz the wifi works find on the ubuntu image that comes from artik, so I will try using the wifi connect on that default ubuntu and if wifi connect works with no issue, then your teammates will be able to fix the issue imo.

@majorz I'm trying to test wifi connect on the base ubuntu image and getting error:

@majorz What is the proper dbus location when not running inside a container

[andrewjaykeller]

I solved a lot of my issues and was able to SEE ALL THE WIFI NETWORKS!!!!!
