I've got a WRT54G v4 Broadband router. It's wired directly to a desktop PC and I use a DW6000 to get to the internet. All of that works fine. I'm trying to connect a Wireless laptop but it doesn't see the router. I've got a good signal on the laptop and it appears to be sending and receiving packets of something when I look at the network status. When I use the Linksys CD to try to setup a wireless network, it says "SecureEasySetup requires that the WI-FI system application be installed a current version. Please ensure that the application is installed and the version number is 3.90 or higher." I've googled for help but I'm not getting anywhere. Somebody suggested I need more up-to-date router firmware but I can't find anything newer than my v4.20.6, May 26, 2005. Can anyone help? Thanks.
