options iwlwifi remove_when_gone=1

Since then I had no Problem anymore with connection after wakeup from suspend to ram or suspend to disk. More Option for the module

modinfo iwlwifi | fgrep parm

Does your wifi device support p2p-client/p2p-go interfaces? You can check under interfaces by doing “iw list”
