Just use the howto for kernel 3.2 (I know it's a little tricky for now to use 3.2, wireless-next is also OK for that howto): http://wireless.kernel.org/en/users/Drivers/b43#Other_distributions_not_mentioned_above You have to: 1) Clone git repository wireless-next 2) Apply 3 patches from this patchset 3) Compile kernel with B43_PHY_HT 4) Install firmware (I think you already started that part) b43-fwcutter in 015 version is alright for extracting 666.2 firmware. -- Rafał _______________________________________________ b43-dev mailing list b43-dev@lists.infradead.org http://lists.infradead.org/mailman/listinfo/b43-dev
