Gaming Lag: Wireless but not Ethernet

Hey guys,

I recently purchased a Sony S15 laptop, one of the early '13 models with Windows 8 on it. So far I'm enjoying it--aside from one main issue, gaming lag. This is something I only experience on wireless (and on multiple networks, not just my home), though it seems to be fine on ethernet, and only on this laptop running Windows 8. I run anything on Win7 on my home network or these other networks and I've never had an issue.

Yes, I completely understand that wireless can be unstable. No, my wireless connection is not. I've played side-by-side with other people running Win7 who have completely seamless connections. I'll be running perfectly well but get massive latency spikes every dozen to thirty seconds. I've done some looking into it and people have reported issues with the 'Homegroup sharing' or 'Apps' trying to connect or sync and disrupting it. I've tried to disable these functions with no success (at dropping the ping).

The main culprit is svchost.exe (LocalServiceAndNoImpersonation), which I know can be many things, but could help pin it down.

Thanks in advance.

tldr; Wireless on Win8 has periodic lag spikes while same wireless on Win7 does not. Ethernet on Win8 runs without spikes.

Do you get dropped packets if you ping your gateway?

ipconfig will show your gateway

ping xxx.xxx.xxx.xxx -t (Xs are your gateway)

You should not get any dropped packets

If its fine with a cable and fine with W7 machines on the same WIFI, it suggests a problem with the laptops wifi, have you checked the sony site for driver updates? It might be a known issue

I realized I should've made this a discussion...

I did try this, and after spamming it a few times I did get a response that shows it: 4ms, 4ms, 576ms, 198ms; no dropped packets. I will reinstall the most recent drivers but I've already done this.

You could try running netstat -e command to see if your connection is really okay.
That being said, I'm experiencing the same lag on my desktop running wifi at home - killed a hardcore char in d3 that way recently).
Anyway, at work we've experienced lan driver issues with serveral laptop models. A Fujitsu model where they consequently were unstable using the provided drivers - new intel ones fixed it. And the hp model I'm using now also did poorly on wifi until I updated to intel drivers instead of hp's - in short try getting the newest wifi drivers from the chip provider if possible (broadcom doesn't provide them)

I have seen a delay every 65 seconds that is due to periodic background scanning that Windows (XP/W7/W8?) networking performs to maintain seamless wifi roaming capability. This is obviously of no value for a stationary computer, and the background scanning can be suppressed by enabling "streaming mode".

Microsoft document "Delivering Lync 2013 Real-Time Communications over Wi-Fi" mentions streaming mode to avoid audio glitches in Lync and Skype, but it applies to any streaming media. See section 5.1.4: http://www.microsoft.com/en-us/download/details.aspx?id=36494

I found WLAN Optimizer http://www.martin-majowski.de/wlanoptimizer/ to enable streaming mode on the fly.
