Hi, For anyone who has encountered serious wifi performance regression after upgrading to crux 3.3, try the lastest kernel 4.10-rc8. Or like me, just keep using the old one. To compile kernel 4.1.13 against gcc 6, you have to: cp linux-4.9.6/include/linux/compiler-gcc.h linux-4.1.3/include/linux/compiler-gcc6.h The broken wifi driver is rtl8192ce, see here for the details: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/log/drivers/... - phi
