DS connection help

[Vipershark]

That depends. (I'm assuming you have a WRT54G, it's what I have)

If the lock is gray, it's most likely set to WPA. DS models before the DSi don't accept WPA, so you'll need to set the router back to WEP settings. While this makes your network much less secure (WEP is relatively easy to crack), you can connect to it.

You'll generally have a code made of random numbers and letters (yes, the hex code you mentioned) and yes, anything else connected to the network will have to reconnect using the hex code rather than the current WPA password. Make sure to write it down somewhere.

either that, or buy one of those nintendo brand USB dongles off the internet

I haven't been able to connect using my DS because my router is set to WPA, and setting it to WEP will just create a huge clusterfuck since everyone in the house has multiple things that connect to the network, so I didn't even bother.
