Hi Guys,

I'm having an intermittent problem with my wireless Intel IPW2100 running Fedora Core 5.

When I cold boot the system, I manually start the network service but sometimes when it tries to initialise eth1, it fails and says the device is not present.

When I run iwconfig, the wireless device is there but is given a random alias of dev<number>. When this problem happens, it won't let me run any of the wireless commands because it can't talk to the device.

I can normally fix the problem by removing the module and re-installing it (with the modprobe command). I'm using the very latest IPW2100 drivers and IEEE80211 subsystem.

This problem is really starting to bug me. Below is a dump of one instance I had this problem and fixed it by reinstalling the module:

I'd greatly appreciate if anyone has any suggestions.
