Apologize for this being in the wrong forum if it is . . . AND for such a basic question to what is so obviously an informed group of networking gurus, but here goes anyway: I have a WRT54G hardware version 1.0, running Linksys official firmware version v2.04.4, although I doubt it even matters because my question is so basic LOL. In the <Wireless><Wireless Security> screen of the router's config, I'm running * WEP Security Mode * Default Transmit Key =1 * WEP Encryption 128 bits 26 hex bits And there's a Passphrase and four Key fields with a lot of characters in them. I've never understood how to cross-reference these fields to those required to set up the PC side of things. For example, on my PC's (Windows XP) wireless adapter properties, under the wireless network properties, <Association> screen, it wants me to enter a "Network key," but only has eight characters (hidden out). Even ONE field of the router's config (either passphrase or any single one of the key fields) has like 4 times this number of characters!! I don't remember what I entered for those eight characters (my connection is working), but now I need to add another PC and can't figure out what to put in that field on the new PC Help! Also, why is the "Default Transmit Key" =1 when there are FOUR keys listed in the wireless router's config screen?!?
