Force network manager to wait before configuring a wifi card

Here is my problem. I have a wifi card handled by the iwlwifi module. I use network manager with the nm-applet to manage it. Sometimes, but not always the wifi card just don't work: it keep trying to configure it before claiming that no network is available (when in reality there is a strong wifi signal). However, I notice that this problem never happen if I disable the auto-connect feature and connect each time manually by clicking the icon. I guess it is because network manager try to configure it too early, before the module has initialized the card or load a necessary firmware. I am not quite sure it is that but I would like to try to convince network manager to wait a few seconds before doing anything with the card and see if it solves the problem. Is it at all possible?

Re: Force network manager to wait before configuring a wifi card

Not sure how to delay NM startup, but I'd want to be certain of the root cause before making any changes.  To that end, can you post:

The wireless card you're using:

lspci -v

...(or use lsusb if its a USB-connected wifi card)

The journal output for a particular boot where you saw the issue:

journalctl --boot=0

...(for current boot, -1 for previous boot, etc.)

The output of

dmesg

...for a boot instance where the issue occurred.
