Aspire Switch 10 の起動ログに
[ 10.650227] rtl8723bs: acquire FW from file:rtlwifi/rtl8723bs_nic.bin [ 10.650301] rtl8723bs mmc0:0001:1: firmware: failed to load rtlwifi/rtl8723bs_nic.bin (-2) [ 10.652184] rtl8723bs mmc0:0001:1: Direct firmware load for rtlwifi/rtl8723bs_nic.bin failed with error -2
とあるので、non-free-firmware から rtlwifi/rtl8723bs_nic.bin を導入してみる
