I found a fix the wifi issue on the HP DM1Z. HP released a Bios Update F.02 / F.13. This update was to add the Intel 6230 2.4 and 5GHz dual channel N plus bluetooth to the whitelist of adapters. I previously tried to add just a 6200 and it wouldn't work. I have confirmed that the 6230 works and gets 150-300mbps. Thank You HP!!!!!
