Wifi connection Not Working Properly on Ubuntu 24.04 (dual-boot)

mahdi-nux · March 30, 2025, 8:08am

System Information:

OS: Ubuntu 24.04 LTS

Wireless Adapter: AzureWave AR9485 (Atheros AR9485)

Driver: ath9k (Automatically Loaded)

linux$ lspci -nnk | grep -iA3 net
03:00.0 Network controller [0280]: Qualcomm Atheros AR9485 Wireless Network Adapter [168c:0032] (rev 01)
	Subsystem: AzureWave AR9485 Wireless Network Adapter [1a3b:2c97]
	Kernel driver in use: ath9k
	Kernel modules: ath9k

Problem Description:

I installed Ubuntu 24.04 LTS as a dual boot alongside Windows on my laptop (Asus), but I have trouble getting my Wi-Fi adapter (AzureWave AR9485) to work properly.The system detects the adapter, but the connection is either very slow, unstable, or sometimes doesn’t work at all. I have searched through many forums and tried multiple solutions, but nothing has worked.

What I Have Tried So Far:

Checked if the Driver is Loaded:

linux$ sudo dmesg | grep ath9
[    4.093916] ath9k 0000:03:00.0 wlp3s0: renamed from wlan0

Checked Wireless Interface Status:

linux$ iwconfig wlp3s0

wlp3s0    IEEE 802.11  ESSID:"Mahdi"  
          Mode:Managed  Frequency:2.437 GHz  Access Point: 66:2D:95:97:01:00

          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:103   Missed beacon:0

Checked Network Interface Status:

linux$ ip link show wlp3s0 
3: wlp3s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP mode DORMANT group default qlen 1000
    link/ether 54:27:1e:17:4c:73 brd ff:ff:ff:ff:ff:ff

Tried Restarting Network Services:

sudo systemctl restart NetworkManager

Reinstalled Firmware:

sudo apt update && sudo apt install --reinstall linux-firmware

Tried Manually Connecting to Wi-Fi:

nmcli device wifi connect "MySSID" password "MyPassword"

Checked the Wi-Fi adapter is blocked

linux$ rfkill list
0: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: no

Reloaded the Wi-Fi driver

linux$ sudo modprobe -r ath9k
inux$ sudo modprobe ath9k

Current Issue:

The Wi-Fi connection is very slow (Bit Rate stuck at 1 Mb/s).

The connection randomly drops or refuses to connect.

Signal strength appears fine, but performance is bad.

Other devices work fine with the same Wi-Fi network.

Questions:

What could be causing the slow speed and instability of my Wi-Fi connection?
Are there any specific driver settings I need to adjust for the ath9k driver?
Is there an alternative driver or firmware update that I should try?

Any help would be greatly appreciated!

The ath9k module has never worked well with TKIP encryption and that is used on your access point

Thank you for your help but my problem still exists.
I changed my access point and now I use my cell phone’s hotspot that uses CCMP encryption as you can see in new output.
Now the Bit Rate (my network actually) is unstable. It sometimes gets high and then lows again.
Also I can see repeated DMA failures that causing connection drops.

After each DMA failure it tries to reconnect

Maybe the answer is at https://askubuntu.com/questions/1531967/ath9k-wi-fi-driver-doesnt-work-properly-with-new-24-04-1-lts-and-kernel-6-8-0
I don’t have a working computer with the ATH9485 wifi to test the change to /etc/default/grub

mahdi-nux · March 30, 2025, 9:59pm

Ok, my wifi is fixed now.
Just wanted to say a huge thank you for helping me solve my WiFi headaches! no more random dropouts, and my connection is finally stable.
