Wireless debugging [Solved]

Wireless debugging [Solved]

Postby bobw » Oct 11th, '15, 20:14

How is it possible to debug wireless problems (client side) when no messages show up in the journal?
Furthermore, when I turn off 'Allow roaming of access points' in my wireless configuration it doesn't update the config file
because it's checked when I go to configure it again....

kernel 4.1.8-desktop-1.mga5
64bit.

What messages don't show up, and what were you looking for?

For debugging, please at least provide some basic information, like:
Which desktop environment are you using? Do you use net_applet or NetworkManager?

And please provide the output of the following commands:
Code: Select all
lspcidrake -v | grep -i -e net -e wireless -e wifi
ps -ef | grep -v grep | grep -ie net -e wpa


and, as root:
Code: Select all
ifconfig -a
rfkill list all
systemctl status network.service -a
journalctl -ab -u network
journalctl -ab | grep -iE "fw|firmware|iwl|wifi|wire|80211"

bob       8931  8126  0 18:06 ?        00:00:06 /usr/bin/perl /usr/bin/net_applet


I expect to see network messages in the journal as the wireless is attempting to connect to the access point.
If it fails, I would expect messages as to what the root cause is...

As it turned out, /etc/wpa_supplicant.conf was trashed. I have no idea how, but it had incomplete entries in the network sections.
