Asus RT-AC66U+Asus USB-N66, huge lag/ping spikes

post #1 of 8
Thread Starter 
Couple a weeks ago, i bought this setup, Asus RT-AC66U+Asus USB-N66 to replace my Linksys E4200 Router+D-Link DWA556 Extreme PCIe Wireless adapter. i had to replace the PCIe adapter with a PCIe SATA controller due to lack of SATA ports, so the Asus USB-N66 seemed to be the best choise.

The problem:

Most of the time, there is no issue, i have good signal strength both on 2.4 and 5Ghz, and there is no issues while downloading huge files over night or gaming.

But sometimes i get this HUGE ping spikes in BF3, it can start out fine, after a couple of minutes, the game just go haywire and my ping is reaching 1500-2000. I reboot my router and reconnect my USB adapter and everything is fine again, and i can play for days without any issues.

I'm using the 5Ghz band on this computer, as i have several other devices running the 2.4Ghz.

I had no such issues on my previous wireless setup.

Anyone with the same setup? or with the same issue?

Not alot to go on.

But, my best guess is the drivers for the USB-Wifi device or drivers for the USB-Controller it self.
Another possibility is that the USB-Controller might have some hardware issues that rarely affects performance.

Get the absolute latest drivers for the USB-controller from the manufacturer and not from ASUS.
Install the latest chipset driver with the online installer at Intel.

Update the USB-Wifi device drivers+firmware.
Update router firmware to latest or try DD-WRT.

Disable QOS and Firewall/SPI in router.

*Edit:
Do not forget to get the latest BIOS
And here is the latest USB3 driver. Newer than the one given by Asus.

Here is the latest driver for the USB-N66.
http://dlcdnet.asus.com/pub/ASUS/wireless/USB-N66/DR_USB_N66_1007.zip

Again, get the latest Chipset driver for the motherboard.. and flash the latest BIOS.

I think the only changes for the newest driver on the N66 is support for Windows 8, the driver version is exactly the same.

The chipset is already the newest version..However my network has been fine for several days now. i have hardreset my router, so lets see how it goes in the next days,

Then my best bet is USB driver or controller going haywire in some rare, yet unpredictable situations.

Hi Simkin,

I also have the RT-AC66U, and I have been getting a lot of ping spikes while playing BF3 just like you mentioned. I found that turning off UPnP helps reduce the spikes, but doesn't stop them completely. Makes playing BF3 a bit more bearable. I'm using firmware version 3.0.0.4.260. I was using the latest firmware, but I found that some of my home wireless devices where not able to connect, or even find the wireless access point.

Hope it helps.

I ended up sending my USB-N66 back, and replaced it with the Ethernet version, EA-N66.

Now, even if it is better, i still get this ping spikes in BF3, but they seem to go away by itself after a minute or so, so i dont need to reset anything. Still annyoing.

However 4-5 times the lights have started blinking on the device, saying it have low signal strength (according to the manual), and the 5Ghz just loose its signal, this have happend 4-5 times, and i have to reset and whatnot to get the signal back, log back in to my network and so on.
