It has always been the case with my laptop and another usb N adapter I bought a while back but this time when i upgraded my PC and got a DWA-552 adapter and the problem occurs again I was forced to try and debug it.

PingPlotter had a constant ping check on my router's network address every second, every few minutes and sometimes seconds apart there would be 100+ ping spikes which always correlate with troublesome lag spikes in-game. And that's with Roaming Policy set to very low. Once set to normal it got much worse with 500+ ping spikes, and just to cement the correlation I set the policy to very high and 1000+ ping spikes happened.
Could it be that DIR655 incorrectly reports to the adapter that it is about to drop the connection forcing a roam that results in nothing but a latency hiccup? I am not well versed in wireless mechanics. These ping spikes are often accompanied with packet loss.

My DIR655 has several G cards connected to it (which work fine btw, my 552 seems to work fine in G mode too though I haven't tested it extensively yet -  may be forced to since dir655 appears to be bugged with N mode) and several N cards that aren't used for gaming so this issue has never been a problem before.

Does anyone have at least an inkling to a solution here?
Thank you.

Link>Welcome!
What Hardware version is your router? Look at sticker under router.
Link>What Firmware version is currently loaded? Found on routers web page under status.
What region are you located?
What game are you using?
Has a Factory Reset been performed?

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: - Log into the routers web page at 192.168.0.1.
Turn off ALL QoS or Disable Traffic Shaping (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 under Advanced/Firewall.
Enable uPnP and Multi-cast Streaming under Advanced/Networking.
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

Link>Wireless Installation Considerations
What wireless modes are you using? Under Setup/Wireless/Manual.
Try single mode G or N or mixed G and N?
Channel Width set for Auto 20/40Mhz or try 20Mhz only.
Try setting a manual channel to a open or unused channel. 1, 6 or 11. 11 for single mode N if the channel is clear.
What security mode are you using? Preferred security is WPA-Personal. WPA2/AES Only. Some WiFi adapters don't support AES, so you might want to try TPIK only or Auto.

Any cordless house phones?
Any other WiFi routers in the area? Link> Use InSSIDer to find out. How many?
Turn off WISH, and WPS under Advanced.
Try turning off Short GI, WLAN Partition,and Extra Wireless Protection if you have it. Under Advanced/Advanced Wireless.
Ensure WMM Enable is ON.

Turn off all anti virus and firewall programs on PC while testing. 3rd party firewalls are not generally needed when using routers as they are effective on blocking malicious inbound traffic.
Turn off all devices accept for one wired PC while testing.

I will try some of these things later. I doubt it can be blamed on other hardware/software because this problem does not persist when I switch to G only in adapter advanced settings. Which obviously means the problem is only with DIR655 and it's handling of N connections in a busy environment (other router, internet phone, both wireless and wired computers etc...) if any of these things must be disabled for DIR655 to suddenly start handling N properly it is no solution but a faulty wireless router.
