[SOLVED] Fresh install, Wi-Fi not connecting

Hi guys,

I've been using Linux for ~3-4 weeks, starting with Mint and then migrating to EndeavorOS, and then to vanilla Arch. In the previous distros/installs wifi worked immediately, and without issue. However I was unhappy with the amount of fluff that came with Mint/Endeavor and decided to move to vanilla Arch w/ KDE (plasma-desktop).

Initially the wifi card wasn't even detected in ip link, but this was solved by installing the broadcom-dkms package. Now the wifi will not connect. I have tried connecting through wifi-menu, NetworkManager, and the plasma-nm widget. Connection times out.

as a note: linux-firmware is installed, and wpa_supplicant.

This is the result of lspci -k:

04:00.0 Network controller: Broadcom Inc. and subsidiaries BCM4360 802.11ac Wireless Network Adapter (rev 03)
        Subsystem: Broadcom Inc. and subsidiaries Device 0619
        Kernel driver in use: wl
        Kernel modules: bcma, wl

and ip link:

3: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state DORMANT mode DORMANT group default qlen 1000
    link/ether 7e:01:6e:12:75:54 brd ff:ff:ff:ff:ff:ff permaddr 50:3e:aa:e4:25:e0

Following the installation wiki I have run ip link set wlan0 up (as shown above). dmesg | grep firmware returns no results. I've also tried to set wlan0 down and then up again as suggested in another thread, but that made no difference.

Running nmcli device wifi list displays the wifi networks available, including the one I am trying to connect to (home wifi) with all the SSID etc information. running nmcli device wifi connect SSID_or_BSSID password password (with appropriate information) returns opens a KDE Daemon prompt to enter the wifi password and then after ~10 seconds returns a "wireless network could not be found" notification above the plasma-nm panel widget.

nmcli device returns:

enp5s0  ethernet  connected     Wired connection 1
wlan0   wifi      disconnected  --

here is the result for find /etc/systemd -type l -exec test -f {} \; -print | awk -F'/' '{ printf ("%-40s | %s\n", $(NF-0), $(NF-1)) }' | sort -f:

dbus-org.freedesktop.nm-dispatcher.service | system

systemd-timesyncd.service                | sysinit.target.wants
xdg-user-dirs-update.service             | default.target.wants

If i try to connect using wifi-menu, all wifi networks are detected but connection immediately fails and asks if I want to keep a generated profile.

And I think, finally, rfkill list shows:

0: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: no

I've tried a few other things but I've forgotten what they are right now. But I think that just about covers everything.

I am new, so there is something I am missing, but I've followed the wiki and done plenty of Googling and can't figure this out .

Thank you all for your time

edit: I fixed it. Apparently somewhere along the way I had installed IW as well, so I removed that and upon reboot the wifi connected without issue. I suppose there was some kind of conflict between IW and wpa_supplicant and/or NetworkManager. Not sure if I should delete the post or leave it here with the solution since it was so simply and fast.
