That's the LAN card. We all know the model on the D630.
I meant the info for the Wireless card! Until we find out the model and ascertain the kext that supports it, you could stay in the dark... Maybe you don't need the patched IO80211Family kext at all.
myFix repairs file permissions (ownership + Read/Write/Exec attributes) and renews Kernel/kext cache. Since you said your LAN had worked before but no longer was, I simply concluded that there was a possibility of a need for myFix.
If IO80211Family is indeed required, you'll always need to use it and possibly port it at system upgrades. Regarding Lion update, do not update via Apple Menu -> Sotfware update or you'll screw up your installation. Download and install the 10.7.5 combo update off Apple website and, before reboot, re-run EDP kext installation.
Read-up past threads, it's all out there.
