hi,

my wifi works well on kernel version " 4.9.13-200.fc25.x86_64" , but it
become so unstable & keeps disconnecting frequently if i use newer
kernels , i sent attachments  & i hope i can be useful in solving such
problem , thanks for your concern.

kernel-4.9.13-200.fc25.x86_64 ( wifi works good on that)
kernel-4.9.14-200.fc25.x86_64  ( wifi keeps disconnecting)
kernel-4.10.5-200.fc25.x86_64  (wifi keeps diconnecting)
