[Solved] WiFi networks recognized, can't connect - SVF14A16CLB

Hi everyone, it's been a while since I've used Arch and it's also the first time I'm installing it on a laptop, so I appreciate your help!
Even though the system boots and installs perfectly (installed everything through a wired connection), I cannot seem to get the WiFi working. Ethernet's not an issue and I can actually see the networks and attempt to connect, but no matter the frequency, protocol or security settings the result is always the same.
I've tried installing broadcom-wl and broadcom-wl-dkms, but I have a feeling I'm doing something wrong since it's not working (and most people with a BCM43142 seem to have no problem using it). Because of this, I'd be super grateful to anyone who could give me a detailed step by step on possible solutions.
I'd like to add that I am able to connect to WiFi networks indirectly by using my phone and tethering it to my laptop via USB, which I guess isn't that troublesome. Finally, ESL so let me know if something's not clear enough.

This does look strange:
ip link reports the WiFi adapter to be "enp0s20u1" whereas iwconfig says "wlp7s0".

But what you might additionally check is that the router is not sending on a channel the like 12-14 as the regdomain of the adapter is set to "00" - world regulatory domain and thus won't connect to any WiFi that only transmits on those channels - these are blocked in 00.

Just checked, channel's set to 11 and I tried other channels but the results were the same. This is getting way too frustrating

I also did "ip link" again and for some reason wlp7s0 now appears there too (I edited the first post with the new info).

If you set up netctl-auto and start the service - can you post the dmesg of that?

I set up netcetl-auto for the wlp7s0 interface, here's the dmesg:

So netctl-auto is just running? Can you provide
systemctl status -l netctl-auto@wlp7s0
the problem is that I canmot find an error yet – it *should* work

Here's the "Dpto" profile the dump is referring to:

Hm, I thought that it might be related to a similar problem I do encounter sometimes, that is, the regular domain is changed constantly and this is hinderin a connection. This seems not to be the case.

Have you tried a different driver (b43 instead of broadcom-wl)?

Re: [Solved] WiFi networks recognized, can't connect - SVF14A16CLB

b43 states that my device is not compatible with the driver.

When I try to connect to any network through wifi-menu here's what I get (the network was preconfigured by netctl-auto, when it wasn't configured by that service wifi-menu simply returned a "Connection failed" message):

"Interface 'wlp7s0' is controlled by netctl-auto
WPA association/authentication failed for interface 'wlp7s0'"

Another thing I don't understand is why the dmesg dump mentions a BCM4365 hybrid wireless controller, since I have a BCM43142.
Edit: Nevermind, that seems to be a common thing with the driver so I doubt it's a concern.

The "WPA association/authetication..." -error is just a really general error that actually does not say anything, mostly.
Can you get a dmesg from the time when you are trying to connect to it?

About the hybrid-controller thing:
This means that you have both: A WiFi and a Bluetooth controller, together called BCM43142. Probably it does mean that the WiFi chip inside is a BCM4365.

That's the dmesg I get immediately after failing to connect with wifi-menu.

There are a lot of problems with that WiFi adapter on 6.30.223.248 driver, especially with WPA2 Enterprise network (certificates instead pre-shared key like in WPA2 Personal).
If I were you, I would try that patch (I can confirm, that it works on kernel 3.19.3) or broadcom-wl-dkms from archlinuxgr repo.

Re: [Solved] WiFi networks recognized, can't connect - SVF14A16CLB

The package from that repository seems unstable, after installing it it appears I have a connection to the wireless network but soon after my system hungs. I'm guessing it's because it was designed for the 3.18 kernel?

Edit: Nevermind! I think I finally got it. Replaced netctl with NetworkManager and things seem to be running smoothly for now, thanks for all the help!
