Hello all, I am having similar problems with my wireless card. It will just disconnect me at random intervals without warning. Sometimes it will happen after a few minutes, sometimes after an hour, but never more than that. And when I go to the network device manager and try and re-activate it, most of the time it tells me that device "Determining IP address.....wlan0 not found.... Check cable?" Sometimes I get that the MAC address has changed, even when I put it in manually. I am using FC3 and ndiswrapper on a Dell 1450 USB wireless adapter. Where can I find the connection setup so that to change the active time option. Are there any other things that I can do to try and trouble shoot this? I am very new so I dont know where to even begin. Thanks, Charles On Tue, 22 Mar 2005 15:04:11 +0000, Sharon Kimble <skimble04@xxxxxxxxx> wrote: > Scot L.
