I don't know if that LFS is too old, but since you say it runs, I guess it is not old. Your problem might be related to this: SIOCSIFFLAGS: Operation not possible due to RF-kill There are two types of RF-kill ... Soft and Hard type. Hard type means it is hardware blocked. Most laptops have hardware switches/buttons that turn wifi on/off. But since that is an usb chip, I doubt that ... Soft type is software blocked and it is done within kernel itself. You can use this simple tool to check wether your wireless is soft or hard blocked. It also can unblock soft-blocked chip. http://linuxwireless.org/download/rfkill/ Just use ussual build instructions, no additional deps except kernel and compiler are needed from what I know. Just a note ... Hard block can occour if firmware is missing, and iirc, rtl_wifi needs firmware. I am not sure tough for the driver downloaded from their site, but one in the mainline kernel needs firmware from linux-firmware git repository at kernel.org https://git.kernel.org/?p=linux/kernel/git/dwmw2/linux-firmware.git -- http://linuxfromscratch.org/mailman/listinfo/blfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
