  • Odd. I also got a Vaio Pro 13, and although I also have issues with my Wifi, my computer uses iwlwifi. Could you post a lspsci?

  • You're relatively lucky, I've got one which won't even connect to a successfully scanned network; the search hints that nvram file is quite platform-specific (and this is the reason it's not generally shipped), try looking for other brcmfmac43241b4-sdio.txt variants but do back up what you already have (probably as /lib/firmware/brcm/brcmfmac43241b4-sdio.txt). Might be useful either: wireless.kernel.org/en/users/Drivers/brcm80211

Try this:

Edit your iwlwifi.conf

nano /etc/modprobe.d/iwlwifi.conf

Comment the last three lines and add this:

options iwlwifi bt_coex_active=0 power_save=1

Your file should end like this:

# /etc/modprobe.d/iwlwifi.conf
# iwlwifi will dyamically load either iwldvm or iwlmvm depending on the
# microcode file installed on the system.  When removing iwlwifi, first
# remove the iwl?vm module and then iwlwifi.
#remove iwlwifi \
#(/sbin/lsmod | grep -o -e ^iwlmvm -e ^iwldvm -e ^iwlwifi | xargs /sbin/rmmod) \
#&& /sbin/modprobe -r mac80211
options iwlwifi bt_coex_active=0 power_save=1

Reboot
