Here's the MAC address fix for your Pros running CM7. If you have had an issue connecting to wifi, it's probably because each time the device's wifi is restarted, a new MAC address is generated which will clog up your router as you can easily run out of IP addresses to lease to each and every new MAC address that's generated each time your device's wifi is restarted. The link can be downloaded here. The instructions are simple:
1. Flash it in clockwork no need to wipe anything
2. "Activate it" by going into the terminal emulator app, typing "su" (without the quotes) then typing "fix-mac-address.sh" (without the quotes). A bunch of weird symbols should come up, but that's normal.
What this does is it auto-generates and writes your permanent MAC address to a file called called nvs_map.bin under /data/misc/wifi/nvs_map.bin. It will remain there and your MAC address will remain the same unless you wipe your /data whereas you will simply have to redo it
