Followed the instruction and it is working.
pls takenote that "Must boot from BOOTMII" is very important, i missed the part and linux reported "cannot read /proc/net/wireless"
after follow exactly the instruction, now it is working ~~
Thanks~
btw i feel this a good time to remind you guys that sea of thieves was made by rare, who also made DKC1-3 and DK64, alongside banjo kazooie and conker's bad fur day
