Waqnis, I don't think you are understanding what is being relayed. Let me put it another way. The reason the old laptops work and the new one doesn't is most likely because the secruity standard encryption style you are using (WEP) is an outdated type that newer computers no longer use. As such, newer computers like your Asus won't know how to communicate the secruity password you are entering and thus will not connect which is what you are stating is happening.
To test this theory, what BC Advisor is saying is log into your route via a web broswer (where you type web addresses such as www.google.com, instead type in 192.168.1.1). It may ask for a username/password. This is different than what you use to login to a computer or to your wireless when connecting to it. It would have been setup when you initially configured your router when you first bought and installed it. If you don't recall putting one in, depending on the make and model of router, you can google for the default admin login credentials. I.E. if I have a DLink MGL-5000 for instance, I would google search "DLink MGL-5000 default admin login password" or something similar to get that information. Once again, depending on the manufacturer, it could be admin with no password, admin/admin, etc. that that search will help you to determine. The make and model should be readily visable on stickers on the router if not a part of the design.
Once you login to the router, look for a secruity section by browsing around until you find the area where you can setup passwords for the wireless connection. Remove the current password and save the setting change. Sometimes the router will just simply have a checkmark to disable the security all together to make this easy. Once disabled and or the password removed, you may be prompted or need to reboot the router. I would recommend if it doesn't do it automatically to just go ahead and pull the power plug from the back of the router and wait about 30 seconds and then plug it back in.
Now that the security is disabled and the router reset/rebooted, try connecting again with your new Asus laptop. If it connects and works, it is the security encryption standard that is incompatible with the new hardware. You can do one of the following:
- You can check your routers security settings as well as the older laptops to see if you can adjust your password to run on WPA/WPA2
- You can get a USB wireless adapter that matches the older WEP standard and run it on your Asus
- You can get a USB wireless adapter for each of the older laptops that works with the new WPA/WPA2 standards and run them on your old laptops (make sure drivers are available for Windows XP)
- You can run without a password (not advised)
