[SOLVED] Another broadcom wifi issue...

Hello all, this is my first post! I decided to make the leap to arch last night, to give me something new to learn, however, after installing it successfully (im able to boot into arch without the live usb) i have no wifi. The only way i can have internet access is if i boot through the live usb, wifi-menu to connect to my network, then mount and chroot into the arch install. Please keep in mind that i am writing this post and doing all of my research from my phone. Here are some command outputs:

lspci -v | grep Network
02:00.0 Network controller: Broadcom Inc. and subsidiaries BCM43142 802.11b/g/n (rev 01)

yay broadcom
community/broadcom-wl-dkms 6.30.223.271-19 (1.5 MiB 7.6 MiB) (Installed)
Broadcom 802.11 Linux STA wireless driver

broadcom-wl is also in the list ^

pacman -Q linux && uname -r
linux 4.20.11.arch2-1
4.20.11-arch2-1-ARCH

Please do ask for any other commands and i will do my best to provide the output, but also please be patient as i only have my phone able to connect to the internet and use a browser.

Re: [SOLVED] Another broadcom wifi issue...

What have you done in the new system to configure wifi?

wl is the right driver for that device.  Check the output of `ip a`, is the wireless device listed?  If so, just go through the connection steps:

Ive stopped my ethernet and wireless service and then enabled and started NetworkManager. Not sure if this is enough, but i get a failure in name resolution if i ping google.com for example, so i cant proceed with the link you provided.

Output of ip a:
1: lo: (loopback, not going to write this out because phone keyboards)
2: enp3s0: <NO CARRIER, BROADCAST, MULTICAST, UP> mtu 1500 qdisc fq_codel state DOWN group default qlen 1000
link/ether 3c:07:71:68:eb:5e brd ff:ff:ff:ff:ff:ff
3: wlp2s0: <NO CARRIER, BROADCAST, MULTICAST, UP, LOWER_UP> mtu 1500 qdisc fq_codel state DORMANT group default qlen 1000
link/ether f6:a8:73:9a:5a:d1 brd ff:ff:ff:ff:ff:ff

Thanks!

No it isn't.  If you want to use NetworkManager you'll need to configure it by at least selecting the wireless network (SSID) you want to connect to as well as providing any relevant passwords/credentials.  But I'd strongly advise stopping NetworkManager and following the manual connection steps to troubleshoot.

However, at the moment there doesn't seem to be any issues with your hardware: this is not a "broadcom wifi" issue, you just need to confgure your connection.

Ok im going to go ahead and do that now. Could you kindly provide me with links to actually set up my connection manually, without NM, and then i can mark this as closed or whatever it needs to be. Thanks again!
