I tried to us a usb portable hard disk on the router. I was able to activate SharePort and was able to access the drive data from the direct link and mobile app.
However, I notice that the wifi will fail after 10 to 15 minutes. My wifi will show as connected, but status will be "may not have internet connect".
Once i unplug the usb drive, wifi seems to recover. I wonder whether this is due to any setting? or is it the router problem?
