Hello, I have an Edimax EW-7811UN wifi usb adapter, this one:
80% of time it works fine, it connects at boot and everything works.
But there are times it would not connect at boot, thus leaving my (headless) pi “isolated” from my wlan.
I can easily see because the led on the wifi adapter stays off when that happens.
In that case, I just reboot volumio(I have a button) and then it works fine.
I don’t know why it does that.
I’m using WEP, I need to use wep for other reasons.
Also need static IP, this is my etc/networks:
iface lo inet loopback
#iface eth0 inet dhcp
iface wlan0 inet static
I see no errors on boot when it happens. The feeling I get is that’s kinda acting like there is a timeout, if it doesn’t connect inside that time frame it just stops trying and continues booting without wifi.
I also disabled the power saving of the wlan adapter, by creating /etc/modprobe.d/8192cu.conf
# Disable power saving
options 8192cu rtw_power_mgnt=0
This solved a problem with wlan shutting off after minutes of inactivity, it did change nothing on this boot problem.
Are there logs to check to see what’s happening?
