What region is everyone from?
When upgrading FW, are you doing a factory reset first, upgrade the FW then doing one more factory reset then set up from scratch using a wired connection? This ensures a good seating of the FW file using this process.
For now, use v1.01.18 as others have downgraded to this version and seems to work. I've passed this on to D-Link for review.
Please be patient.
