[BPI-R4] wifi7 card not working

Banana Pi Router design BPI-R4(MT7988)
1

I tried to get the r4 be14 wifi card working, but somehow its not recognized. lspci lists nothing. dmesg is here: [ 0.000000] Booting Linux on physical CPU 0x0000000000 [0x411fd090][ 0.0 - Pastebin.com

i already recompiled the image and added all drivers that i found with mtk7798/7796 (not sure which chipset is used in the wifi card and i was too lazy to check it, so i added both). iw list also returns nothing.

anyone an idea whats going on? did i use the wrong module? if so, can someone please tell me what is the chipset of that card so i can add the correct module? :slight_smile: thanks!

Card is not supported yet in linux/openwrt and firmware for it is in testing state…

oh, that explains a lot :slight_smile: thanks

Ah,mom…lspci lists nothing…then i guess you missed the sw4 to provide 12v to your card…but be careful when switching back to your old cards…normal mpci cards do not like the 12v…that will give a nice firework.
