Several problems with wifi/wireless connection in live environment

Striker · 2017-12-26 01:41:02

Hello, I've been trying to make wifi internet access work in the Arch live environment in order to actually install Arch in my laptop's HDD but I'm running into a series of problems.

My adapter, according to the output of "lspci -v" is a "Qualcomm Atheros QCA9565 / AR9565 Wireless Network Adaptar (rev 01)", and the kernel driver in use is "ath9k". The laptop itself is an Acer Aspire ES 15 (ES1-533-C27U). I've set my router to use no password or encryption algorithm for the wireless connection for now, in order to make things easier while I try to make it work in my notebook and avoid problems with authentications that may happen.

Now, let's get to the problem. Running wifi-menu in the Live environment and connecting to the wireless network simply ends up in a temporary black screen while it tries to connect, and an eventual "CONNECTING FAILED" error in wifi-menu. Running "journalctl -xe" gives me this at the end of the file:

archiso systemd[1]: Failed to start networking for netctl profile wlp2s0-TP-LINK_C37682

I've tried to connect with iw as well, by doing this:

ip link set wlp2s0 up
iw dev wlp2s0 connect "TP-LINK_C37862"

And all I get is a timeout.

Another thing I tried was setting a wpa_supplicant config file called in /etc/wpa_supplicant called "example.conf" which contents are like this:

network={
ssid="TP-LINK_C37682"
key_mgmt=NONE
}

Which is supposed to work for networks with no password, then running "wpa_supplicant -i wlp2s0 -c /etc/wpa_supplicant/example.conf". This is what I get as output:

Successfully initialized wpa_supplicant.
wlp2s0: SME: Trying to authenticate with 14:cc:20:c3:78:62 (SSID='TP-LINK_C37862' freq=2462 MHz)

wlp2s0: CTRL-EVENT-SCAN-FAILED ret=-16 retry=1

And it goes on like this until I terminate it.

So, I'm at a loss as to what to do to get WiFi working on this. I even modified my network through the router so that it's not protected by any password or encryption algorythm and is not hidden but it still gives me authentication and association errors like you can see above. What should I do? I'm willing to give any additional info needed.

MAC filter?

Nope. No MAC filtering is active in the router.

And actually, I tried using a Ubuntu Live USB yesterday and managed to connect to it in that live environment... but not only did it fail quite some times before I was able to, everything is super slow even when I'm almost glued to the router. In Windows this problem isn't present and it works nicely everywhere in the house. In Arch it simply doesn't connect anywhere and throws those authentication errors.

Module parameters.

parm:           debug:Debugging mask (uint)
parm:           nohwcrypt:Disable hardware encryption (int)
parm:           blink:Enable LED blink on activity (int)
parm:           led_active_high:Invert LED polarity (int)
parm:           btcoex_enable:Enable wifi-BT coexistence (int)
parm:           bt_ant_diversity:Enable WLAN/BT RX antenna diversity (int)
parm:           ps_enable:Enable WLAN PowerSave (int)

I'd start w/ ps_enable and nohwcrypt
If you've got a BT device, rfkill that to get it out of the way (you're on 2.4GHz)
Enabling debug might get you somewhere.

I'd otherwise blame powersaving tools (powertop, laptop-mode-tools, tlp) but not on the installation iso...

Sorry, I'm at a bit of a loss as to what to do. I managed to block bluetooth with rfkill block bluetooth, but how can I check those modules and their parameters?

The module is ath9k, you can check the parameters using "systool -vm ath9k".
The reload ath9k altering the parameters: https://wiki.archlinux.org/index.php/Ke … le_options

I tried reloading ath9k altering the ps_enable and nohwdecrypt values to both 0 and 1 in all possible ways according to the instruction in the wiki page, but the connection problems still remain. Bluetooth is still blocked so as to not interfere with wireless, and I also messed around with the bt_ant_diversity and bt_coex_enable params but no luck as well.
