[Solved by downgrading kernel] WPA issue [probably hardware?]

pirj · 2014-08-04 15:47:37

Spent 3 hours trying to restore my system that doesn't want to connect to my home wifi AP (keenetic lite) with WPA2 anymore.

Workaround:
Connect manually to Guest network protected by WEP.

ip link set wlan0 up
iw dev wlan0 connect Guest key 0:secret

It's taking a long while to connect. Sometimes you need to put wlan0 down and then back up, usually many times.

And it wasn't very straightforward to figure out how to set it up properly on Keenetic, there's an option in web UI, but you have to telnet and issue

ip nat GuestWiFi

.

Problem:

# netctl start zyxel
# dmesg -w

All netctl and netctl-auto profiles are disabled and stopped.

I've tried to tweak

ipv6.disable=1

Kernel setting, no difference, just that IPv6 message went away.

None of my neighbours APs has the same frequency/channel.

I've added to zyxel profile:

TimeoutUp=300
TimeoutCarrier=300

Didn't affect anything.

I've played with

iw wlan0 set

txpower, power, frag and rts as section 3.7 Connection always times out of Wireless network configuration advises.
RTL8188 doesn't seem to support iw's power commands.

Sometimes it authenticates, but fails to assiciate:

And sometimes in dmesg TADA!:

Sometimes it works for Guest network, and in rare cases with wpa_supplicant.

Is that [quot]At the times of 3.15 kernel rtl8188eu driver is buggy and has many stability issues[/quot]? It as working flawlessly for couple years. What happened?
Is there any way to use dkms-8188eu from AUR?

Or do I just go and buy an external USB WiFi dongle that just works? Any advises which one? Will TP-Link TL-WN727N work fine?

UPD: bbcodify

UPD: After update to linux from 3.15.7-1 to 3.15.8-1 I experience random disconnects with no trace in

dmesg

.

iw dev wlan0 connect

doesn't retry, so I need to sit in console and repeat it by hand. Argh.

UPD: Downgraded to linux-3.14.6-1. Everything works fine, no timeouts, no long connects, both wpa_supplicant and

iw dev wlan0 connect

work super sharp.

Looking into 8192cu-dkms from AUR.
