hello to everyone. i hate to pester the public with my problems, i’m writing as a last resort.
a while ago i acquired an hp pavilion x2 detachable 10 k-000. it’s a convertible tablet running on atom Z3736F. since its performance with windows 10 was uber crappy, i decided to try it with linux. i’m an experienced (though in no way expert - intermediate at best) linux user, though my experience is limited mostly to debian; however, i went for manjaro after gathering some info and seeing some random guy describing better support.
now, the tablet’s performance is like 10x faster than before and everything is supported almost ootb. except wifi. the kid’s running a realtek rtl8723bs integrated chip (it showed up as such on windows and i literally pried open the machine to confirm - it is also soldered directly onboard so no way to switch it with, say, an atheros card) which has wifi and bluetooth functionality. the strange thing is, bluetooth works like a charm: i am able to connect bt headphones, and to use bt tethering with my phone. it’s just wifi - the system does not see a network card at all.
before deciding to open this topic i spend a couple weeks googling around and digging the knowledge base. apparently there was a driver available here, which was however merged with mainline kernel and became the r8723bs module, which i am using to no avail.
linux-firmware is up to date and i have rtl8723bs_ap_wowlan.bin, rtl8723bs_nic.bin and rtl8723bs_wowlan.bin in my firmware folder, however they are all symlinks to the corresponding binaries for rtl8723bu. i did not go around and manually mess with files in the fw folder, however i tried loading the 8723bu module, also to no avail. some guys suggested switching wifi mode from ACPI to PCI at bios, too bad there’s no such option in mine (and no custom bios out there afaik, but please prove me wrong).
so i kinda ran out of options and i’m here for help.
attached are the outputs of inxi, lsmod, lspci, lsusb etc. i can provide anything else as needed.
TIA
