i am running a raspberry pi B+ headless and losing network connection irregulary.
I am living with that since a few years, but now want to fix the problem.
What would be a good approach to find out the reason?
My countermeasures so far
Thanks for any directions
A few thoughts :-
This post shows a couple of possibilities. https://www.raspberrypi.org/forums/viewtopic.php?t=129021 MrEngman I gather wrote a helpful installer script for the Edmix range of Wifis. Research a bit more yourself before trying these perhaps.
1) Remove ifplugd
apt-get purge ifplugd
2) Disable any conflicting drivers, read in more detail before doing anything, but e.g.
blacklist rtl8192cu blacklist rtl8xxxu.conf
Have you tried updating your raspbian/kernel/firmware? It might help fix the situation. https://www.raspberrypi.org/documentation/raspbian/updating.md
sudo apt update sudo apt full-upgrade
It may be possible that your power supply may be a bit too weak/unreliable to drive the USB wifi.
I remember my EDIMAX clone wifi being quite cheap and a pain to setup and use. Buying a different brand may help, though I notice the Pi brand can have this problem too.
Treat yourself to a newer Pi with built-in Wifi ;)
