Well that's it for this device.
The internet connection finally stopped working altogether after one of its regular dropouts and it had to be rebooted. It's a brick. I'm now up running on the old NETGEAR one. Back to 10/100 but at least working.
If I'm lucky I'll get my money back. I'll not be getting another of these or probably any D-link device after this debacle.
A small message to D-Link.
Test your instructions in real-world situations. If the instructions are incomplete, correct them.
If AV or firewall need to be disabled include it in the product specific documentation and don't expect your customers to look at some other generic document located somewhere else on your site. They shouldn't have to.
And just as a final suggestion, this device has a USB port. How about modifying your system by having the boot process look for FIRMWARE.BIN in the root directory of any attached USB storage device and doing a firmware flash if it finds it. On successful completion it could then rename FIRMWARE.BIN to FIRMWARE.BIX and reboot thereby avoiding a continual cyclic flashing. Perhaps even automatically do a full restore back to factory default settings as this would probably have been a "last resort" fix.
