This Forum Beta is ONLY for registered owners of D-Link products in the USA for which we have created boards at this time.
I cannot downgrade with 1.33. You will need a NON-Dlink customized version. I do not recommend this since you will be exposed to possible malicious coding (it's NON-DLINK and possibly even illegal to do so, the firmwarecode is not Open source or GPL).
The firmware is from the dlinkru website, and very legal to do!!!!
or you use the ubiocom source file.
