I have a linksys WRT54GS2. I forgot my password, so I pushed the little reset button. I reset the router and had to configure it all again. I thought it had it configured, because you can see the router name on the "view networks" page, but it just doesn't connect for some odd reason. What could this reason be? I have my router password protected, and I am sure I typed in the correct password.
I know my question was a little hard to understand. My desktop is hard wired to the back of the router. After setting up the router, I can see the broadcasted ssid on the connections screen. I am however unable to connect to the router, even when I know my password is correct. (on my laptop)
I messed with it today, And I got it working without a password, but when I put a password in it screws up again.
Let's eliminate the confusion between passwords and security keys. The router password only allows you into the interface to be able to change settings. When you performed the hard reset, that password defaulted to whatever is printed in the router's manual - possibly "admin" or "password". The only other password in there is in your ISP login but as you say you got it working, that must be right. What remains is the wireless security key and you should find that under the wireless settings.
Are you saying the connection to the Internet works without a security key but will not when you set one up? Are you certain you're inputting that key properly into the laptop when trying to conenct?
WPA is the lowest level you really should have - WEP is easily hacked these days. The key will be case sensitive and probably eight characters. Change it for something else if you like. Before that, try adding the network as a Preferred one in XP in the left hand pane of the View Wireless networks form. Enter the SSID or network name, and the WPA security key - twice - and save it. It may just wander in by itself and remember the way in future.
