CBX,
I just purchased a DS-2CD2432F-I (no 'W'). Yes, no wireless, but interestingly, the wireless module and antenna are on the board.
So, I assume the hardware is the same between the DS-2CD2432F-I and the DS-2CD2432F-IW, which probably means that the manufacturer is just changing the firmware, much like how it makes Chinese and English versions of the cameras.
I assume it might be possible to do a patch similar to the Chinese day of the week fix to make the wireless work. Does that seem like it would work?
Anyway, if you'd like to investigate this, great. If not, I'll get to it as my interest waxes and wanes.
Obviously there are ethical issues with actually making the wireless work on a device sold without it enabled. Personally, I do not intend to benefit from this- I just want to see if it could be made to work (but I really prefer running it wired), but I understand that others may profit off of it, causing the manufacturer lost profits.
I assume this is why a there is no permanent fix for the Chinese day of the week. Though there might be checksum issues in making a fix in the flash, they probably are not insurmountable.
