New finding: Latency & WiFi issue

Hi-
 
I recently started having major issues streaming live TV, recording audio, etc. when my WiFi connection is enabled. The audio and video stutters and stops briefly and repeatedly. I ran LatencyMon and the DPC execution time and latency shoot way up when WiFi is connected. My resource usage is quite low. Right now, for instance, it's 8% CPU, 18% Memory, 0% Disk & Network.
 
I've tried resetting my router to no effect. Comcast has not been helpful. I haven't installed any apps lately and I tried updating my graphics & sound drivers, but that didn't help. I'd rather not have a service call from Comcast if it's something on my end, but I'm running out of things to check. This all worked fine up until about 10 days ago.
 
Any ideas?
 
My system:
Samsung Series 7 Gamer NP700G7C-S01US 17.3-Inch Laptop
2.30 gigahertz Intel Core i7-3610QM, 16 GB RAM
Windows 10 x64
 
Speedtest results: 80.29 mbps download, 6.07 mbps upload
 
Thanks!
 
-Susan
 
P.S. My PC is connected to the router via Ethernet, but I have to have WiFi on to connect to the Internet. I thought I could bypass the WiFi connection to get on the Internet at one point, but maybe I was imagining that?
 
P.P.S The worst offenders acc. to LatencyMon are dxgkrnl.sys and ndis.sys.

    I'm no expert, but having two interfaces (WiFI and ethernet) going at the same time just plain sounds wrong. I say this because there would need to be some sort of arbitration between the two.
     
    Not sure what type of router you have, but if it is actually a modem/router (i.e. a DSL or cable), there no reason why you shouldn't be able to hit the internet via an ethernet connection.

    Hi Susan, Windows has an "auto detect" feature built in, and that pings around every 4 seconds and spikes the crap out of latency. This post is linked to a few items, but the one which may be most applicable is here (i.e., how to shut network discovery off, also the first link in the first post). Sorry for the daisy chaining; I never got around to consolidating all of that stuff. HTH

    Susan,
    I agree with SuperG.  Just to clarify, are you saying that if you disable wi-fi, your internet connection to the PC (via ethernet) is lost?

    Hi All-
     
    Solved! When these problems started, I lost the ability to connect to the Internet via Ethernet and wasn't even aware of it since I was still able to get on with the wireless connection.
     
    I ran a diagnosis on the Ethernet connection after seeing your questions and got a Windows Sockets registry entries missing and then a DCHP error. I was able to correct both of these and now I can connect to the Internet directly via Ethernet and the latency issue is gone (at least reduced by a lot.)
     
    Thanks so much for pointing me in the right direction!

    Hi Michael-


    I tried your suggestion after getting my Ethernet connection working again and it seems to have helped quite a bit. I'm still getting some stuttering while live streaming, but I think it might be a graphics card driver issue.
     
    Thanks very much!

    I was still having severe latency issues to the point where my NI Komplete Audio 6 interface control panel said my computer wasn't able to handle real-time audio.
     
    I finally tracked this down to my laptop running at *very* high temps for both my CPU and motherboard. Once I resolved that, the latency problems disappeared and everything is back to normal. For anyone else having similar problems, that's another thing to check. I used Speccy, but HW Monitor provided similar results.
     
    One happy camper-

    That is a very good point (and why I am not a fan of laptops or overclocking 24/7). The engineering design of electronics fall apart quickly once temperatures fall outside of "normal operating band." "Limits" are the extreme values for most cases (with design buffer) to prevent damage, but the performance does drop off before that point.
     
    Windows-based programs that tap into the computer sensors are highly advisable for anyone until they know what things look like "typically." For electronics, the cooler the better...

    Are you seeing any new wifi activity e.g. from your neighbours?  There are a limited number of channels available and quite often they'll interfere with each other.  I ditched mine recently (more as an experiment to take some of the load off the USB subsystem really, and to free up a USB port) for a new pair of home plug devices which work much better than wifi in a house.

    Hi Michael-


    I've always used desktops and much prefer them! The only reason I'm using a laptop now is because I inherited it from my Dad and its specs are much better than what I had. I'd be limping along with SONAR with my old desktop. My laptop still feels foreign to me after 3+ years, since I can't just open it up and swap out this, that or the other. I consider myself lucky that I had nothing worse than massive latency considering the internal temps were maxing out the readings.
     
    Thanks-

    Hi ston-
     
    I'm all set for now (see above.) It was a combination of WiFi being enabled when it didn't need to be and extreme overheating, which I've since resolved.
     
    Thanks-

    Cool over heating , will reduce cpu speed wirch increase dpc latency

    P= f * V°2 *£

    P = heat
    F = cpu frequency
    V = voltage
    £ = adjustement coefficient

    To reduce P , f gonna be lowered and so v .... Basically this is what happen to macbook pro , when it s overheated , they loose perf

    My last advice , is if you go laptop , go with real Pro ones ( hp zbook , hp elitebook , dell precision , lenovo w series ect )

    LOTS of folks have issues with DPC Latency spikes that are triggered by their WiFi adapters.  The simple fix for that for ME (and many others) is to disable the WiFi adapter (some laptops have a function key or a physical switch, or they go into Windows Device Manager and Disable it there).  THEN Sonar can be launched and the WiFi isn't there to interfere with latency during the Sonar session.  Once finished with Sonar and it is closed, then simply turn WiFi back on (or Enable it in device manager), and all is back to working fine.

    Hi Bob-
     
    I disabled WiFi (see post#5 above for details) and that helped quite a bit, but my PC was also running *very* hot and once I solved that everything went back to normal. So I actually had two separate issues, but all's good now.
     
    Thanks!
