netctl: impossible to connect to a WPA-encrypted Wi-Fi network

zoug · 2015-07-12 13:57:47

Hello,

I'm running into big problems when trying to use netctl to connect to a WPA-encrypted Wi-Fi network. This is happening for months already and for the two Arch installs I did but I never really needed a wireless connection but will in a few days, so I need to get this sorted out!
I generated a profile with wifi-menu and checked the key a thousand times, the same key works for my phone and for the same laptop from the same location when using Windows. The connection actually happens, it's just that I sometimes have a tremendous packet loss when using ping (something like 80%) or sometimes it works perfectly but still no internet connection. The messages I have on dmesg sometimes mention the infamous "reason 3" and sometimes (like now on my sample output) don't, and in both cases I can't use the Wi-Fi network. wpa-supplicant is installed, my Broadcom BCM4313 is, it seems, supported by a driver loaded by the kernel so no extra work on my part should be necessary, I really don't know what's going on.

ping output: http://arin.ga/7ljoEP
systemctl output: http://arin.ga/znYkXp
dmesg output: http://arin.ga/dhpInh

Could you guys help me? Do you need any other information?
Thank you!

Based on what? All the resourses on the wiki say otherwise. The b43 listings have an explicit "no" in the 4313 rows while brcmsmac has more of a 'maybe':

Please note: at least BCM4313 is not fully supported. Some models appears to work (users reported success), but some don't, and there's no indication that this is going to change.

So lets start with that. What driver are you using? What is the actual device ID (from `lspci -vnn |grep -i net`)?

Okey, this is awkward... I didn't notice the "Please note" on that exact same page you mentioned, for the brcmsmac driver. I just saw the name of my Broadcom and assumed it's supported since it's in there below "Supported Chips".
So yeah maybe this is the problem after all! Here is the ouput of that command: http://arin.ga/YiaTap

Up! Really would like any kind of solution to my problem, if someone ran into it already or knows what to do... thanks!

Have you tried the wl driver?

No, my model isn't supported by that driver unfortunately (it's also written on the page you linked)

Well, the page says that the device is unsupported but offers "wl/brcm80211" as a potential alternative.

Does the device work in (a live version of) other distributions?

If so, what drivers are they using?

Text based flow chart for Broadcom chips:
1) Do b43 or brcmsmac support the chip: yes, use that; no, go one to two.
2) Try -wl, it will support a vast majority of cards not covered in #1. If it fails go on to three.
3) Use ndiswrapper.

This is all in the broadcom page of the wiki.
