Pi loses WiFi connection after a few hours
-
Hello,
my Raspberry Pi 4 (4GB) seems to lose the WiFi connection after a few hours (I can’t say exactly yet).Whereby this is not correct. The device still has the correct IP address. In the WiFi menu it is connected with the correct SSID. But I can’t ping a device in the network anymore. Also the Raspberry is not reachable from the network.
Rebooting the Raspberry solves the problem immediately.
Power Management: off is already set. What else can I do?
Thanks

Linux script that will check if the wifi on the pi is connected and reconnect if needed. This script is run from the pi. Typically you would set this up as a cron job that would run periodically (e.g. every 5 minutes). If the script detected the wifi was not connected it would attempt to reconnect.

Thank you, at the moment I would like to find the problem. There are a couple of modules on the MM that are using the internet connection regularly. So there should be no need to disconnect.

I have the same issue except rebooting doesn’t correct the issue

At the moment I am doing long term test. A have a new SD Card, with online running raspberry os on it. So far, after 24h the pi runs smoothly and the Wi-Fi is still working.
Tomorrow I will install MM2 on the same card, to see what’s going on.What I need to know is, where to look if after installing MM2 the problems start?

I wanted to revive this topic, as I am having the same issue.
After a day or two, the Raspberry Pi 3 B+ seems to lose it’s connection. I’m not able to connect to it via SSH, and the Weather module stops updating temp/forecast/etc. The news headline module and calendar module seem to continue to update, however.
This problem goes away (temporarily) after a reboot.
Looking at the error logs, I only see this:
[ERROR] fatal: unable to access 'https://github.com/MichMich/MagicMirror.git/': Could not resolve host: github.comI’ve made sure the Pi is updated, and I’m able to ping sites (like github) after the reboot.
Any ideas? I haven’t had any problems until the past month or two.

This Github post seems to describe the same (or similar) issue:

@jca2112 are you running pihole as an advert filter? seem to see this a lot with pihole servers…
i had a system that would lose connection almost daily… (over a years time)finally installed a different network system… google wifi vs router and extenders…
wifi hub in same location as one of the prior extenders
haven’t had it fail since -

Yes, I am running a pihole – thanks for suggesting that. (I should have mentioned it.) I’ve not had any issues with the magicmirror + pihole setup in the past, but just to make sure I whitelisted the magicmirror so it would bypass the pihole altogether. It didn’t seem to affect the problem, so I’m not sure that it is a factor.
