Random DPC Latency Spikes with Intel N6200

I was just monitoring my latency in DPC latency checker when i noticed random spikes in the yellow and red regions. I tried disabling and enabling drivers to find the culprit and found that my new Intel N6200 WLAN is causing these.

At that given time, my wireless router was acting up and net connection was down.

This is from when i noticed it.



This is from when i identified it and disabled it.



This is from when i re-enabled it



This is from when i re-enabled it and switched the wifi off(Fn+F1)



This from when i re-enabled it and net was up and running again.



Now what i am confused is whether this is a common problem when the card is not detecting its preferred network or is there something else wrong here?

Also, is my normal latency(the last one) NORMAL?? What should i do now?

Any insight into this is highly appreciated.

 

Have you tried to install latest drivers for your wireless card. It should help.

 

I have the latest drivers and i havent noticed any latency problems.
Does your laptop actually get laggy - stuttering in sound and such - or is it just the DPC Latency Checker that made you aware of the problem?

 

No, i haven't tried the latest drivers yet. Definitely will give that a try.

I havent noticed it get laggy or stutter as such. And, yeah, I only noticed it in the DPC latency checker. Also, i found that when the router is sending the signal properly, there is no spikes in yellow, or red. It just happens when the router is not functioning. I guess those spikes are due to the fact that the card tries to acquire signal or something. Can someone try this theory out to see if they can re-enact the problem?

 

I wouldnt worry about what DPC Latency Checker tells you. If you actually dont see any problems (such as stuttering sound, laggy mouse or really bad performance in games even though fps is high enough) id say you dont have to do anything...

 

yeah, You are right. I dont see any kind of stuttering or laggy problems at all. Games perform really well too. It just happened when the router was offline. After that, only one spike in yellow region was found. That too, after driver update of 6200, became fine. Now no problem at all. But i am curious as to whether the intel card does that when it is trying to connect and no network is available. Hmm..Curiosity...

 

I have Dell Latitude E6410 with Intel N6200 Wlan card. I produce music and for me DPC latency is major issue. Though it helps to turn off WIFI while performing live, so it's not a problem. But now I have seen a new problem arising:
Seems that when downloading stuff from internet, the faster the worse, my wireless turns off and says that WIFI button is not turned ON, though it is. I have to "repair" wireless connection, to gain access to internet again. But this issue doesn't allow me to download samples and other stuff any more. That's a big issue already. What can I do about it? Is there a fix for this issue?
