First off, I’m running AntiX17 full 64 bit, and using wpa_supplicant and wpa_gui (which are working great otherwise and use very little memory), not wicd or ceni. wicd uses a lot of memory and ceni is not happy roaming.
I was in another town and was using wifi there. I suspended. I got home and woke it up, but wifi was down.
Can someone please tell me what commands to run to diagnose why wifi doesn’t reset, or get it to reset completely without needing to reboot?It will work again if I reboot, but I really hate rebooting all the time and losing everything I was doing. Hibernating and waking up from hibernation didn’t work either. What was odd was that I found that all my network connection options in /etc/wpa_supplicant/wpa_supplicant.conf were disabled except the ones for the place where I was at. I went in and manually removed the disabled=1 lines and rebooted and wifi worked again, but I don’t thnk it should be disabling my wifi connections at all, and when it wakes up, it should connect to whatever it can in whatever sequence the priorities are set at.
Thanks for any info or suggestions 🙂

I was in another town and was using wifi there. I suspended. I got home and woke it up, but wifi was down.
I do not find this behavior unusual. Different router. Different IP.
IF: wlan0 state: upLot’s of fancy readouts. But I fail to see a problem. Must be a cultural blockage on my end.
I realize you got a problem.
It will work again if I reboot, but I really hate rebooting all the time and losing everything I was doing. Hibernating and waking up from hibernation didn’t work either. What was odd was that I found that all my network connection options in /etc/wpa_supplicant/wpa_supplicant.conf were disabled except the ones for the place where I was at. I went in and manually removed the disabled=1 lines and rebooted and wifi worked again, but I don’t thnk it should be disabling my wifi connections at all, and when it wakes up, it should connect to whatever it can in whatever sequence the priorities are set at.
I’m just too thick headed to see it I guess. But then. I use Wicd always. Even on my Pentium 3’s.
Sometimes I drive a crooked road to get my mind straight.

How to Search for AntiX solutions to your problemsRoki, Maybe that’s because I did the listings after I rebooted and things were working again. I am really just hoping to find that someone knows to run this, that and then something else, ie a recipe to diagnose WiFi problems in a wpa_supplicant environment.
Of course, if I could just FIX it, LOL, I guess I’d just move on 🙂
I found that the laptop has a function key on Fn+PrtScr to turn WiFi on and off, and it looks like it works, but I’ll need to suspend and go some place else and wake it up to see if that solves it.
Does anyone know how to see what pressing Fn+PrtScr actually does?

I would just run
ifdown interface
ifup interfaceto cycle your connection down and up and force a reconnect.
Ok, will go try that this afternoon, thanks
So what worked was to wake it up, then I had to press the WiFi on/off key 2 or 3 times, then it was working, then had to use wpa_gui and change to wlan0, the, scan, add the network, then connect. It took a few tries, as i think there was a limit of 10 networks, but all worked.
Thanks everyone

Well, I got home and can’t connect.
When I press the WiFi on/off key I see wifi related programs run, but wpa_gui can’t scan or connect.
Hmmmmm, Neither toggling the WiFi key, nor the ifdown wlan0 followed by ifup wlan0 got it to connect when I got home.
I finally went into wpa_gui and was eventually able to connect to my home WiFi again. I’m still not sure what to do to fix it…
I need to increase my scrollback buffer to see the xev. I will add it to this post once I get the output.
Very odd… So it wouldn’t do anything…
I guess its going to happen all the time, so I’ll put it into a script to run anytime I resume and wifi refuses to work and I’ll call it wpa_reset for lack of a better name.
I found an old ubuntu post from before debian had systemd, and the short story is that I figured out it was blocked, so pressed the wifi toggle, and once unblocked, the code to make it work again was:
