Jeg har kjøpt en superbillig 300M USB Wifi Adapter (lenke til ebay) til min Raspberry Pi 2 (Debian) og trenger hjelp til å få den til å fungere. Slik som det er nå så blir den listet av lsusb, mens ifconfig og iwconfig ikke gir noe. Det ser altså ut som USB adapteren blir oppdaget av OS, men at det ikke blir aktivert. Har funnet ut at chipset skal være rtl8192eu eller rtl8192cu. Ut i fra svar på lignende problemstillinger funnet på andre nettsteder så er det ofte følgende informasjon som blir etterspurt fra de gode hjelperne:
uname -a:
lsusb:
lsusb -vvv:
lsmod:
dmesg:
iwconfig:
ifconfig:
På forhånd takk for hjelp!
