My internet slows down after 'sleeping'

Hi,

I just got a brand new PC 1.5 month ago, but I have noticed whenever I leave my PC and it goes into sleeping mode - and wake it up again, my internet is slow despite Speedtest.net shows I have full 300 Mbps speed. I have tested it on a few sites, where fx the graphics renders slow or download of large files downloads in kb/s rather than mb/s. 

I tried to search the internet for a solution, but most of the sites claims it can be on the other end the issue is (i.e. the remote site is causing the bottle neck), but that is not the case, as a restart of my computer brings it back to normal speed.

It was also suggested to disable/re-enable my ethernet controller (Killer E2400), which I have tried to do without any luck as the result is still slow. I even tried to disable my ethernet and only use my wifi, but it is still slow, so my limited test skills tells me it is something both my ethernet and wifi shares that is causing the issue. 

I also tried to reset (in windows) my Ethernet controller and have it reinstalled but to no avail. The only solution for now seems to restart my PC every time I get into this scenario, which is quite inconvenient. 

Do you have any idea, what else I should look at?

My drivers and Windows updates are up to date. 

The fact that it corrects itself after a restart makes me suspect it is software related and not hardware related.

Hope you can help as it is driving me desperate.

Thank you in advance,

Best regards

Thomas

    I fixed the problem. After digging a little more on the web regarding this issue, I found that not all on/off sleep settings can be found in the Powerplan, but on the actual devices in the Device Manager. Here I went into the properties of my Network Adapters, and disabled the computers ability to shut off the power in the power management tab. I also did this on the 'hidden items' Network Adapters and that resolved the issue. All is good and I can enjoy my new PC. 

    Thank you, though, for your response. It was greatly appreciated.

    Hello again,

    Thanks for the many useful links. Before using it investigating for memory leaks, I want to share some more observations.

    Today I had my PC on for 8 hours straight and never at the time it was on, I experienced my problem. Not after 8 hours either, so I do not think it is a memory leak. Neither do I see excessive usage in my Task Manager after wake-up.

    The minute it goes to sleep and internal fan, drives, etc. turn off - and after waking it up again - the issue is there. I am wondering if it could be related to something on the hardware shutting off when it goes to sleep and never wakes up. I did look at my power plan settings, and ensured it had MAXIMUM PERFORMANCE - or DISABLED (for the USB suspension), but even with those settings on it doesn't help.

    I am wondering - since I see the issue on both Ethernet and Wifi, we should be able to strike out the Ethernet adapter as the culprit, right? 

    The funny thing is:

    • On speedtest.net I get a normal speed (also after wakeup)
    • But surfing is slower
    • Going to https://www.thinkbroadband.com/download trying to download a 1GB file, I see the problem. This is what I use whenever I want to test for the problem. What took less than a few minutes before the sleep, now predicts a 12 hour download after waking up. Again - I dont think it is the remote site, as it works fast again after restarting my computer.
    • Going to the website for my work to login to Citrix (The entry site is called a NETSCALER GATEWAY) takes forever to load - especially the background picture. Normally it takes a few seconds. When I finally log in, I cannot use it as there is a very long delay on my actual movement and the mouse rendering. Again - I dont think it is the remote site, as it works fast again after restarting my computer.

    The latter is the annoying part, which basically means, when I come back from lunch, I have to restart my whole computer to be able to use it properly for work again. 

    So the big question is - how can I have full speed on www.speedtest.net, but at the same time see slow surfing and graphics rendering. I should also add the same behavior is to be found in both Google Chrome and Microsoft Edge.

    My computer is a Dell XPS 8930 desktop computer i7-8700 CPU @ 3.2 GHz with 16 GB ram. NVIDIA GeForce GTX 1050 Ti. As mentioned it is barely a few months old, so it is annoying I have this problem. I think it may be overkill to return it and set it up again for this issue, if there is an easier way. 

    All help is appreciated.

    Thanks,

    /Thomas

    SysInternals has developed several tools that can monitor the system and reveal information on Processes.

    Use Procman to monitor the system.

    Memtest can be used to check Memory. It's the most recommended utility.

    Hi Pat,

    Thank you for your response and your link. 

    Whether or not disabling will help on my problem, I have now read the article and disabled most of the services mentioned. 

    So do you think it is memory leaking from a running service that are cause to my observed issue? In that case, wouldn't I see eventually see slowness even if the PC does not go to sleep?

    If that is the case isnt there a way I can pinpoint exactly the service, that causes this problem? Such as looking at the Memory or Network performance columns in the Task manager?

    All help is appreciated.

    Thanks,

    Best regards

    Hi, Thomas,

    Even though it sleeps, there are still background processes that utilize memory. When you reboot you release the memory. 

    You can disable services that are not necessary. See the following,
