Trouble with Atheros wireless (AR9565) can not connect to open networks

orexisx89 · 09-08-2015, 05:38 PM

Okay so here's my current problem, My acer aspire (ES1-711-P1UV) has been having connectivity issues, Only from what I can see, on open networks.

I tried using wicd at first, though with no success, so I dropped it, purged the packaged using slackpkg and tried just using the command line

iwconfig wasn't working to gain a connection either, Note that this computer is dual boot and runs windows 10 in which the connection in question works fine. after using iwconfig manually, I tries the network manager that is built in to slackware-14.1 (I'm running a modified kernel, the default suffered the same problem, but for clarity I'm running a custom compiled 4.2)

So I reset my rc.inet1.conf to it' default state, made the network manager daemon executable and went on my way.

It sees the network, much like before, it will attempt to connect, but doesn't finish and it deauthenticates and drops the connection. Here's what I've brought for potentially relevant diagnostic material.

Code:

bash-4.2# lspci | grep 02.00.0 -A3
02:00.0 Network controller: Atheros Communications Inc. AR9565 Wireless Network Adapter (rev 01)
03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168 PCI Express Gigabit Ethernet controller (rev 0c)

Code:

ifconfig

        ether c4:54:44:e5:08:18  txqueuelen 1000  (Ethernet)

        TX packets 10  bytes 4066 (3.9 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions

So these tell me what card I have and that it IS being recognized by the system so next I checked to see which driver it was using.

Code:

bash-4.2# nm-tool

        Kernel driver in use: ath9k
        Kernel modules: ath9k

Alright so I know it's running the ath9K module as the driver, So I attempt to check if the ath9k supports the chipset, the result for me in the past using this command usually gives one alias, however this time it gave me a whole mess.

Code:

bash-4.2# modinfo ath9k | grep -i 0036

alright, now that I've got that listed, what happens when I try to make a connection, according to dmesg:

so this is what I have, I don't know what to try from here, if you guys could shed some light on the issues. let me know if you need additional information or need me to run additional commands to get what you need. Any help greatly appreciated

Not sure if this will help but this is all I could find:

https://wireless.wiki.kernel.org/en/users/drivers/ath9k

Dunno if it will help.

Unfortunately ath9k driver is totally broken when using certain cards, this is known problem. I don't have any link to bugtracker with this bug ATM, so I don't know if they eventually fixed it in the kernel. Anyway, you have two options:

1. If driver was fixed (to be honest, I highly doubt it), you can try to compile latest kernel.
2. Use ndiswrapper with Windows XP driver for your card (this is the easiest route, and almost certainly it will work)

Here is the kernel.org bug link:

And Ubuntu:

I haven't really looked through them.
