Hi all,
I have a similar issue on my Dell Vostro 1510. Since the kernel
4.17.2-200.fc28, the wifi didn't work ! But works on kernel 4.16.14-300.fc28.
$ uname -r
4.17.3-200.fc28.x86_64
$ rpm -ql akmod-wl.x86_64
/usr/src/akmods/wl-kmod-6.30.223.271-18.fc28.src.rpm
/usr/src/akmods/wl-kmod.latest
I made a #modprobe wl
$ lsmod | grep wl
wl 6463488 0
cfg80211 770048 1 wl
$
I made a dmesg and I see this:
[ 32.894311] wl: loading out-of-tree module taints kernel.
[ 32.894317] wl: module license 'MIXED/Proprietary' taints kernel.
[ 32.894318] Disabling lock debugging due to kernel taint
[ 32.902941] wl: module verification failed: signature and/or required key
missing - tainting kernel
Also:
$ grep CONFIG_MODULE_SIG /boot/config-$(uname -r)
CONFIG_MODULE_SIG=y
# CONFIG_MODULE_SIG_FORCE is not set
CONFIG_MODULE_SIG_ALL=y
# CONFIG_MODULE_SIG_SHA1 is not set
# CONFIG_MODULE_SIG_SHA224 is not set
CONFIG_MODULE_SIG_SHA256=y
# CONFIG_MODULE_SIG_SHA384 is not set
# CONFIG_MODULE_SIG_SHA512 is not set
CONFIG_MODULE_SIG_HASH="sha256"
CONFIG_MODULE_SIG_KEY="certs/signing_key.pem"
$
I hope this can help you to fix it.
Regards.
