Qualcomm Atheros AR9485 Wireless Bad Signal: Troubleshooting Tips

When it comes to wireless connectivity issues with the Qualcomm Atheros AR9485 chipset, one common problem that users face is a poor signal strength or intermittent connectivity. In this article, we'll explore some troubleshooting tips to help you resolve these issues and enjoy seamless wireless connectivity.

Firstly, it's worth noting that in newer kernels, disabling the 802.11n protocol can also disable the 802.11ac protocol and limit the device throughput to 54 Mbps. This is because many routers do not support the 802.11ac protocol, especially older ones. As a result, it may be necessary to force disable the 802.11n protocol to achieve better wireless connectivity.

One simple trick to try is to disable the 802.11n protocol altogether. To do this, open the terminal and use the following command: `sudo rmmod iwlwifi`. This will remove the iwlwifi module, which controls the 802.11n protocol. Note that this may not work for all devices, especially those with newer kernels.

Another solution is to force disable the 802.11n protocol by adding a line to the configuration file. To do this, open a terminal and use the following commands one by one: `sudo su`, `echo 'options ath9k nohwcrypt=1' > /etc/modprobe.d/nf`. This will enable software-based encryption over hardware encryption for your adapter.

It's also worth noting that some users have reported success in improving their wireless connectivity by disabling the 802.11n protocol altogether. To do this, open the terminal and use the following command: `sudo rmmod ath9k`. This will remove the ath9k module, which controls the 802.11n protocol.

If none of these solutions work for you, it may be worth trying a different solution or seeking further assistance from your router manufacturer or network administrator. With a little patience and troubleshooting, you should be able to resolve any issues with your Qualcomm Atheros AR9485 wireless adapter and enjoy reliable and fast wireless connectivity.
