Hi all,
my wifi connection is lost often on KaOS. But for the same computer, as dual boot with Debian12, connection is good and never lost.
Device: Network controller: Qualcomm Atheros AR928X Wireless Network Adapter (PCI-Express) (rev 01)

Is it about the driver or not?
Waiting for your help, regards

Can you provide some logs? Easiest will be to use Octopi > Tools > SysInfo, that way more detailed info about what driver is loaded, and possible error log.
KaOS uses IWD, does Debian use IWD or wap_supllicant? Networkmanager?
Also, usefull info might be obtained with restarting IWD manually after a connection is lost:

sudo systemctl restart iwd

if that alone does not restart the connection, follow up with:

sudo systemctl restart NetworkManager

Network:
Device-1: Realtek RTL810xE PCI Express Fast Ethernet vendor: Toshiba driver: r8169 v: kernel
port: 3000 bus-ID: 02:00.0
IF: enp2s0 state: down mac: <filter>
Device-2: Qualcomm Atheros AR928X Wireless Network Adapter vendor: Askey WLL6080 802.11bgn
driver: ath9k v: kernel bus-ID: 03:00.0
IF: wlan0 state: up mac: <filter>

Please re-read my previous post, with the asked for logs, not much anyone can do to help.

log file is up to 3000 lines, is it possible?
