from some updates, my wireless card (or wireless management) has lost a lot of its performance.
I have several PCs and laptops with linux mint and for some time in this pc, the downloads have become very slow.Network controller: Qualcomm Atheros AR9227 Wireless Network Adapter (rev 01)
Subsystem: Qualcomm Atheros AR9227 Wireless Network Adapter
Kernel driver in use: ath9k
Kernel modules: ath9k
To give you an idea the same file downloaded with another PC at 3Mb/s, with this PC the download at 30Kb/s, yesterday "sudo apt-get update" took 24 minutes and often I lost the connection. Adding a usb wireless key, the situation improves a bit in terms of stability, but not much in download speed.
I searched for new drivers or solutions online, but I couldn't find a solution.
Can you help me figure out how to get my wireless card back to its normal speed?
