When it is working, it will work forever, as long as I don't turn the computer off, or put it in sleep mode. Many times when I turn on the computer, it works, but many times it doesn't either.
I've made no changes to the router settings since the day I set it up. It's all about the router just flat out losing communications with whatever USB device I have plugged into it, ie a printer, jump drive or portable HD. When this happens, Shareport activates as it should, but the link to the USB device is apparently open, as I don't get the customary USB connect tones.
In order to get it working again, I have to power down the router. It then starts working again.
D-Link Tech Support seems to think the solution to every problem is to reset the router to factory defaults or upgrade the firmware. This is BS. Everytime you do that, you have issues with settings, passwords on Wifi, etc. Hopefully someone out there has solved this issue.......I've seen many posts talking about exactly this issue.
