- What Hardware version is your router? Look at sticker under router.
 - Link>What Firmware (http://forums.dlink.com/index.php?topic=47512.0) version is currently loaded? Found on routers web page under status.
 - What region are you located?
 
Internet Service Provider and Modem Configurations
- What ISP Service do you have? Cable or DSL?
 - What ISP Modem Mfr. and model # do you have?
 - Check ISP MTU requirements, Cable is usually 1500, DSL is around 1492 down to 1472. Call the ISP and ask. Link>Checking MTU Values (http://forums.dlink.com/index.php?topic=53008.0)
 - For DSL/PPPoE connections on the router, ensure that "Always ON" option is enabled.

				Router and Wired Configurations
Some things to try: - Log into the routers web page at 192.168.0.1. Use IE, Opera or FF to manage the router.
- Turn off ALL QoS (http://vonage.nmhoy.net/qos.html) or Disable Traffic Shaping (DIR only) GameFuel (DGL only and if ON.) options, Advanced/QoS (http://en.wikipedia.org/wiki/Quality_of_service) or Gamefuel.
 - Turn off Advanced DNS Services if you have this option under Setup/Internet/Manual or under Setup/PARENTAL CONTROL/Set to>None: Static IP or Obtain Automatically From ISP.
 - Enable Use Unicasting (compatibility for some ISP DHCP Servers) under Setup/Internet/Manual.
 - Turn on DNS Relay under Setup/Networking. Link>Finding Faster DNS Addresses using Name Bench (http://forums.dlink.com/index.php?topic=53222.0)
 - Setup DHCP reserved IP addresses for all devices ON the router. Setup/Networking. This ensures each devices gets its own IP address when turned on and connected, eliminates IP address conflicts and helps in troubleshooting.
 - Ensure devices are set to auto obtain an IP address.
 - If IPv6 is an option on the router, select Local Connection Only or Disable IPv6 options under Setup/IPv6.
 - Set Firewall settings to Endpoint Independent for TCP and UDP under Advanced/Firewall.
 - Enable uPnP and Multi-cast Streaming under Advanced/Networking. Disable uPnP for testing Port Forwarding rules. Enable IPv6 Multi-cast Streaming for routers that have a Media Server option. Disable IPv6 Multi-cast Streaming if IPv6 or Media Server is not being used.
 - Turn off WISH, and WPS under Advanced.
 - WAN Port Speed set to Auto or specific speed? Some newer ISP modems support 1000Mb so manually setting to Gb speeds can be supported by the router. Advanced/Advanced Networking/WAN Port Speed
 - Set current Time Zone, Date and Time. Use an NTP Server (http://forums.dlink.com/index.php?topic=48695.0) feature. Tools/Time.

				Are there others online while you are sending to the router and USB drive? 
Ensure your 3rd party security PC programs are temporarily disabled while xfer'g files.
I recommend that you might want to phone contact your regional D-Link support, ask for level 2 or higher and see. 
This seems to be a possible problem either with the ISP possibly or the router.
Let us know how it goes.
