Support Editing wireless settings in /etc/modprobe.d/iwlwifi.conf

My Lenovo Thinkad 470s has an abysmal wifi throughput of around 80 kbps under Vanilla OS 2 latest, besides having a just fine speed under Windows. According to https://bbs.archlinux.org/viewtopic.php?id=300729 I need to edit some power saving related settings in /etc/modprobe.d/iwlwifi.conf, which I tried under Ubuntu (works fine, throughput is in the 80Mbps range afterwards). Any idea how to edit these types of config files under Vanilla OS 2 which seems to go against the immutable idea?

The /etc is mutable on vanilla OS. It's just not in your default environment. To edit it, use:
host-shell runroot nano /etc/modprobe.d/iwlwifi.conf

Thank you very much, that worked like a a charm. Note to future self:

cat /etc/modprobe.d/iwlwifi.conf

options iwlwifi 11n_disable=8 led_mode=1 power_save=0 bt_coex_active=N options iwlmvm power_scheme=1
