I have version A3 hardware with the latest firmware installed.  When i use wireless N, after transferring a large file from my PC to my NAS over wireless, the router slows to a crawl once the file is done.  The next file i try to transfer moves at about 200-300kB/s as opposed the the previous 8+MB/s.  Watching nextflix and gaming is also slow.  After i unplug and plug back in the router, everything is fine.  It doesn't do it everytime, but does happen often enough to be frustrating. 

After experimenting with different wireless N settings, and trust me i've tried like every combination.  I set the router to wireless G only, the transfer speeds are about 2-3MB/s but it always has that speed.  It's been stable for well over a month now.  But i bought an N router, and want faster speeds.  What's the warranty period for this router?

Has anyone else experienced similar slow down issues after transferring a large file?

Some reading with another user with same situation:

Is your wireless adaptor N supporting?
What wireless modes are you using?
Try single mode N or mixed G and N?
What security mode are you using? WEP, WPA or WPA2? Preferred is WPA-Personal. WPA2/Auto TPIK and AES.
What wireless devices do you have connected?
Any cordless house phones?
Any other WiFi routers in the area?
Turn off Short GI and Extra Wireless Protection if you have it. Under Advanced/Advanced Wireless.
Turn off all anti virus and firewall programs on PC while testing.
Turn off all devices accept for one wired PC while testing.
How far way is the PC from the router?

What ISP Service do you have? Cable or DSL?
What ISP Modem do you have? Stand Alone or built in router?
What ISP Modem make and model do you have?
If this modem has a built in router, it's best to bridge the modem. Having 2 routers on the same line can cause connection problems.

Some things to try:
Ensure DNS IP addresses are being filled in under Setup/Internet/Manual? You can find these under Status/Device Info/Wan section.
Turn off ALL QoS (DIR only) GameFuel (DGL only and if ON.) options. Advanced/QoS or Gamefuel.
Turn off Advanced DNS Services if you have this option under Setup/Internet/Manual.
Turn on DNS Relay under Setup/Networking.
Setup DHCP reserved IP addresses for all devices on the router. Setup/Networking
Ensure devices are set to auto obtain an IP address.
Set Firewall settings to Endpoint Independent for TCP and UDP.

Best thing for NAS is wired for best performance.

Hows this going? Any word? Any feedback on the suggestions?

The DIR-655 has to be set with the mixed mode n/g or n/g/b in order to use the 20/40Mbps transfer speed.  You can try to disable the QoS and the WISH mode if you have a heavy data traffic.
