Hi,

Owner of an Acer Aspire A515-57-762J and installed Ubuntu on it with a double boot with existing Windows 11.

Manufacturer: Acer
Product Name: Aspire A515-57
Version: V1.30

Seems to be pretty stable overall EXCEPT for Wifi which is unusable in everyday usage because the laptop is freezing sometimes.
To avoid this freeze, the only thing I found is to put a new file in
/etc/modprobe.d/iwlwifi.conf
with following content

remove iwlwifi (/sbin/lsmod | grep -o -e ^iwlmvm -e ^iwldvm -e ^iwlwifi | xargs /sbin/rmmod) && /sbin/modprobe -r mac80211

install iwlwifi echo 1 > /sys/bus/pci/devices/0000:00:14.3/reset ; /sbin/modprobe --ignore-install iwlwifi

options iwlwifi 11n_disable=1

the last options directive is the one which makes the laptop not freezing at all but WiFi speed is capped to 15Mb/s at max …

I would like to know if some others users of this laptop is using it with Ubuntu or any others Linux flavors with WiFi OK and full speed like 600 to 800Mb/s ?

At disposal to give some more informations if needed.

Regards,

Laurent
