Loss of wireless connection

[Mercurial]

I have a Linksys 54G router and a linksys 54G PCI card in my system. For the past few weeks I've been able to connect to my router's network (and with 'Very Good' or 'Excellent' connections majority of the time), but I am *constantly* losing my connection to the network. After about 5 to 15 minutes it will drop. I then have to directly tell it to reconnect to the network (even though the network is listed as my primary network to connect to). I have all the latest drivers and firmware updates. My computer is in a slightly out-of-the-way place compared to my router, but for the past couple of months (almost a year) I've never had this problem. Yet even still, if I bring my laptop into the same area, it can still find and stably connect to the network. There is encryption (64-bit). And I can also see other networks available in the area.

Any thoughts/suggestions about what might be causing this loss of connection? Could there be a setting hidden within the system? This will happen in the middle of downloading/uploading information, so it's not an "if idle" setting.

I am running XP, and haven't made any significant driver or hardware modifications in quite a while. Any help would be appreciated!

Reset the router completely and reconfigure your SSID, channel, WEP, etc. I've had routers just go kooky on me and it took a full reset to clear the ghost issues.

Thanks for the comments, but I managed to figure it out last night... there were some authorization options enabled on the pci card that shouldn't have been. After de-checking those, it worked fine.
