I have a Linksys WRT54G router connected to my cable modem and a Linksys WMP54G PCI card in my desktop computer, which is situated about 15 feet away, and is not obstructed by any walls or anything. I have no problems connecting; I get a strong signal. However, the connection gets dropped at a random time several times throughout the day. The dropped connection only lasts for 30 seconds or so before it reconnects, but it happens frequently enough that it drives me nuts. I also have a Centrino laptop that I use to connect to the same network, and it never drops the connection, even when placed in the same area as the desktop PC or further away. This leads me to believe it is not a problem with the router, but with the PCI card. I have tried unplugging my cordless phone system in my house, moving my UPS away from my computer, and I even bought a long anntenna extension on eBay to try positioning the antenna in several different places, but nothing so far seems to help. It also doesn't help if I disable WPA or turn off ZoneAlarm Pro (my firewall on the desktop). I am running Windows XP SP2 and have all of the current security updates. Furthermore, I have the latest drivers from linksys for the PCI card and the latest firmware version for the router. Any further suggestions to keep my connection from being dropped?
