At least on older bcm47xx/MIPS devices nvram was also used for (user changable) configuration like lan ip address, and consequently erasing nvram caused CFE to restore the default values, which should include the right wifi configuration values. Several devices even do so when holding down reset for a long time at power up*. Does this not happen anymore with bcm53xx/ARM? Are user values now stored in a different partition?
