Hello ,
i've bought a TD-W8980 wireless router about an year ago ; It seems to have some problems when i connect one or two usb drives at its usb ports.
The problem occurred also in the first weeks of router's life , later it luckily disappeared . in these days the problem started again.
I use the pppoe interface for wan connectivity and the isp says that no problem is on the line...
Two days ago i updated the device to the last firmware but today i 've the same problem.
Simply any device connected to the wifi or the cable suddenly lose connectivity to the network until i reset the router itself.... as i said , it seems that this problem occurs only with shared usb disks

Thanks for your support
