I am having some troubles with the
wifi on my laptop which has Manjaro installed on it.
Right now, the wifi seems to be working well. It connects at a great speed, and works flawlessly. However, at random points, specifically after rebooting, waking the laptop after sleep, logging off and logging back on, etc. the wifi seems to fail.
By fail, I mean that the wifi symbol shows only an Ethernet icon [I'm using KDE on a thinkpad], and wifi seems to be disabled. After enabling it, the wifi indicator on my laptop turns back on, which is a good sign, and the laptop tries to connect to established networks, only for it to be stuck on
configuring interface, slowly before saying that the network could not be found from my network interface
wlp3s0. I know this isn't a problem with the wifi, because if I reboot, occasionally, it starts working again.
An odd occasion I noticed that could be a wrong assumption on my part is that whenever I tried installing
network-manager-applet, the wifi stayed in the same state as mentioned above, without ever connecting to the internet. I might be wrong, but I've rebooted almost 5 times with that application installed, and the wifi never worked during that time.
I do not know which logs to publish, so if logs are needed, please tell me which logs you would like, cause I have no idea what is going on...
