Ubuntu doesn't reconnect to WiFi unless I reboot
Please provide the output of the following commands
lsmod
cat /etc/modules
cat /etc/modprobe.d/blacklist.conf
If you have b43 module running try blacklisting it and use the module wl or brcmsmac
vim /etc/modprobe.d/blacklist.conf
add the following line to this file
blacklist b43
save the file
vim /etc/modules
add the following line to this file to load wl at boot time
wl
restart your pc
if it doesn't work
try reinstalling drivers using jockey

I am dual-booting my laptop going between Windows 7 and Ubuntu 12.04 LTS. Initially, I can connect to WiFi, but if I get disconnected for some reason, or if I restart my router, Ubuntu won't reconnect unless I reboot my laptop. Just logging out and back in won't work, I have to restart ubuntu, why and how can I fix this?
The output of
sudo lshw -c network

I have installed Broadcom STA wireless driver. I have experienced the same issue before with other distros; Crunchbang doesn't connect to wireless at all, Archbang won't connect to wireless after upgrading pacman. The problem began with Ubuntu, which is why I tried both Crunchbang and Arch and then ended back at Ubuntu.

SDsolar almost 7 yearsI have the opposite problem. This never happened under 14.04 LTS for me. The upgrade to 16.04 LTS is so great I'll keep it, but it keeps forgetting my WiFi password. The service is clearly running; just that it forgets the password and doesn't connect. I posted this: askubuntu.com/questions/934958/… - and I do not want to deal with blacklisting or anything strange.

Lynob about 11 yearsplease read my edit

Abhishek Kandoi about 11 yearsdid you try blacklisting the b43 module and adding wl module to the list of modules to be loaded at boot time
-
Lynob about 11 yearsdpaste.com/917798 see line 35, it says
blacklist bcm43xx
so it's already blacklisted right? aren't you talking about that module? -
Abhishek Kandoi about 11 yearsno bcm43xx module was used in older versions of linux, blacklist b43 and add wl module to list of modules to be loaded at boot time and try again

wl
didn't work but it seems thatbrcmsmac
is working! Will that solve the issue with crunchbang or arch? -
Abhishek Kandoi about 11 yearsthis might help for Arch
