Well, the modem does have firmware (CDMA, UMTS), the Touchpanel has firmware, but as far as WiFi goes, there is no firmware for WiFi that I can tell (looking at a extract of a Verizon Pre2 build webOS 2.2.4), so I am not sure how I would help.

I have had issues with built in apps, they seem fine, and pass doctor checksum check, but fail...
My guess, is the NAND chip is failing and it is writing the drivers right where you have a bad sector or your WiFi chip is failing? I will look later when I have more time to see if I can find any firmware, but I do not think there is such a thing for WiFi subsystem.
Kind of like Bluetooth, it seems to be software driven.
