XP connecting wirelessly to WEP network with Linksys?

Okay, I don't know a lot about the intricacies of connecting to the internet or of routers. I have a WRT54G v6. We have two computers- a dell desktop running Vista and my laptop running XP. I went to the setup page to change the router's security settings to WEP, because I'd just read that Nintendo DS's only connect to networks with WEP. I was able to play with it wirelessly fine after that. I was also still online with the Vista, which is connected with LAN through the router and modem. My laptop, however, doesn't want to connect to the WEP network wirelessly. It doesn't ask me to type in a key when I try to connect. I went to advanced settings, selected the network, and tried typing in the key there too but that didn't work either. Perhaps I'm missing something. I could just switch back and forth between WPA and WEP for whenever I want to play my DS online, but still, does anyone know how I might just connect to the WEP on my laptop anyway?XP connecting wirelessly to WEP network with Linksys?
You need to go to the card's connection program and search for your network, try looking for a profile name and delete the old profile. Then do a search and select your own network, it will either have an automatic key insertion, or a configuration setting for a new profile. You will probably need to tell it the connection is WEP, some cards also require the key to be inserted in 2 digit groups, e.g. :

for a key of a3e2f4 you would need to enter :

a3 e2 f4

I advise using 128 bit WEP, it is not as secure as WPA, but is fine for normal use, and a 36 character hex code entered manually is more secure than a badly chosen simple WPA passkey.

Do NOT just delete your wireless connection, this is often given as a cure all answer, you end up with a network connection called something like Local Area Connection 5 after 5 attempts, and this is because it leaves traces of previous connections behind.

A few cards are even case sensitive and will require the hex letters entered in upercase.XP connecting wirelessly to WEP network with Linksys?
Delete the wireless network on your laptop and then try to connect to the router again. Windows machines save a profile of the wireless network and try to use the same settings as when it first manages to connect until you delete the profile. WEP is a terrible encryption and takes less than 10 minutes to break and gain the security key. I'd strongly suggest using WPA encryption on your router and getting an access point that can be configured for WEP for the DS to connect to so the access point can be unplugged from your network when you're not using it.
