Which updates are you talking about- did you change kernels? Maybe you need to reemerge all the wifi and dhcpcd stuff. I have a D-link Atheros based card, and here's what I do: 1. compile into the kernel all support items for wifi (not modules) 2. emerge all madwifi stuff (tools, driver), and dhcpcd 3. As root, type iwconfig ath0 This brings up the config list, but no essid, and the address is all zeros. then I type dhcpcd ath0 and it connects fine. If I redo the iwconfig ath0 command, it now lists the essid name of my wireless router (linksys), and the numerical isp address dhcpcd found. Hope this helps.
