I just bought the WRT54G router and the WPC54G adapter card for my laptop. I have my desktop hardwired to the new router and have installed the software and adapter card in my laptop. I cannot seem to get the WEP set. I want to set the SSID and the then the WEP to 128. Where do I get the WEP key? What is a Hex digits? Are there already upgrades that I need to download for this router? It is the version 5.
