Can't get it to work

That message is coming from your wired adapter. This is the wireless one. Open the wireless zero configuration utility and pick a network to connect to (make sure you type the password in right, if you have one). Also if your password changed recently, you may have to delete the network from your computer and re establish the connection again.

If this is a new connection for you, you will need to open a command window. Start->Run and type cmd. In there type "ipconfig /all" without quotes, mind the spacing. Find the wireless connection and see if you have an IP address. If not, try another USB port, uninstall and reinstall the device driver, test this on another computer if possible.

Well wires, or fibre optics, is ALWAYS better than Wireless. just as that CC indicated.

all you need is the longitus eterneth cable needed to connect to / from the Dynex 4 port Hub ethernet cable plus a host pc on Dynex 4 port ethernet hub, the host pc you need to specify that you are sharing the connection of internet connection through the eterneth, and ready
luck

i have seen issues with wireless USB adapters. Can you try another USB port on the computer? Also delete the adapter and let it br reinstalled. If this does not help, I would suggest returning it and getting a Linksys adapeter.

Use the XP to config Router.
Your 98 and your router are on different SUBNET check it.
Connect XP computer to Router using lan cable
Be sure to be on same subnet
Configure your Router
SEt same subnet for every PC connected to router.
Then connect to router using Wlan.

According to your user manual pg 2 & 23 (bottom) your device only operates at 54mbps and Pre-N works at 108mbps. The factory ranges can be misleading because their tests are under optimal conditions that we as users will never have.

Have you tried using an ethernet cable instead of a USB cable? USB connections for internet traffic aren't always the best.
If you can make the change to ethernet and then open your command prompt and type ipconfig /all and tell me what ipaddress,subnet mask, and default gateway it says.

look in your manual, turn off your internal modem, wifi. and then plug in your new adapter. restart and see how that works. if not then best buy has a great tec department

Please understand as I get very basic to start but things very obvious to you I cannot see.

Generally when including a router in a home network starting from the cable (tv) or the phone socket (dsl) in the wall with a phone wire plugged in. The next box is generally provided by your internet service provider and is a modem/something that connects to the phone line or cable. Then sometimes when only one computer exists computers are directly connected to the modem with an ethernet cable (looks like a fat phone wire with oversize connectors) or a USB cable (small flat retangular ends).

When you want to add a router for multiple computers. The computer gets disconnected. If a USB cable was used it is often replaced with an ethernet cable and that cable connects to the WAN port (probably separate from a block of 4 lan ports) of the router you bought (tell me if you have two routers -- that is a different problem). If your service comes from a cable (tv) company your router may already be properly configured. If however you have DSL service from the phone company the chances your router is correctly configured are less. To finish with the cabling story -- your computer then hooks to one of probably 4 LAN ports all in a block. Now if you are lucky power on all devices and boot up your computer and see if you have internet access. If you do great if not please provide me the name of your internet service provider or a link to their help/support website and I will see what I can do to assist in completing the router setup. Until your wired computer gets access to the internet your girls wireless connections will not work either. Once we get the wired connection working we will address the wireless connections.
If necessary unplug the router and plug the computer back into the original cable until we get the router working.
