[SOLVED] Can't connect to wireless network

mathmethmoth · 2020-04-27 05:16:01

Hi everyone, I've been using Arch for about two years now and I've never had any issues until now.

I had a problem that forced me to reinstall Arch, deleting all my previous configuration in the process, now I can't connect to WiFi even though I followed the installation guide step by step, I sometimes have issues connecting a wired connection.
The controller is listed in ip link, but whenever I try to connect to a wireless connection it just sits indefinitely.
Here are some outputs:

 $ journalctl -p 3 -xb

My hardware is

 $ sudo lspci -vnn -d 14e4: 
02:00.0 Network controller [0280]: Broadcom Inc. and subsidiaries BCM43142 802.11b/g/n [14e4:4365] (rev 01)

I had to stop dhcpcd in order to be able to connect to a wired connection. I read the Broadcom wireless in the wiki but didn't seem to help.

Any guidelines will be appreciated.

I've already run rfkill unblock all because the modules were soft blocked and didn't help.

The work your way methodically through this page, from the very top: https://wiki.archlinux.org/index.php/Wireless

And the first instruction that fails, post the exact command and the full output.

I think I know the issue, for some reason dhcpcd was conflicting with NetworkManager, I did

 $ sudo systemctl disable dhcpcd

and

 $ sudo systemctl enable --now dhclient@wlp2s0.service

which created a new log, now I have wireless but for some reason I cannot access some websites, says site not available, my /etc/NetworkManager/conf.d/dhcp-client.conf looks like this:

[main]
dhcp=dhclient

Does this looks right?

mathmethmoth · 2020-04-27 08:53:48

Solved,

$ sudo netctl enable wlp2s0

did the trick. Thanks.

mathmethmoth,,

Out of curiosity,

As far as i can read/see, you seem to have two network managers installed/running - NetworkManager well as netctl..
Whilst reading wiki it explicitly says that:

Note: There are many solutions to choose from, but remember that all of them are mutually exclusive; you should not run two daemons simultaneously.

https://wiki.archlinux.org/index.php/Ne … k_managers

..and dhcpcd too..

Unless you disabled one of the network managers?

Admins, apologise beforehand if asking further questions in [SOLVED] topic is not permitted.
