Thanks for the info ala42.
I read your earlier post regarding time on the weekend so please don't get the impression that we are rushing you.
Your efforts are immensely appreciated.
Based on your efforts and subsequent success with the DW1650 firmware it appeared as if you had conceded in your efforts to achieve MCSE compatibility with the new DW1655 firmware.
From what you have posted, there is no need to speedpatch any of the DW1655 firmware as they are not riplocked by default.
Thanks for the information, new lesson learnt.
