Windows 10 constant ping spike

Question

I recently bought a new laptop (about a week ago) but I am constantly getting strange ping spikes that never stop. Tried restarting my laptop, with no avail.

Before I begin describing my issue let me paste the output of the command ping

ping -n 20 192.168.8.1 (my router's ip, approximately same result with 8.8.8.8 or any other ip or website)

Pinging 192.168.8.1 with 32 bytes of data:

Ping statistics for 192.168.8.1:
    Packets: Sent = 20, Received = 20, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 2ms, Maximum = 2904ms, Average = 419ms

With 20 total pings, this command outputs at least two ping spikes ranging from 2000ms to 3000ms, nearly always. I'm pretty sure this problem is related to my laptop (not my router) since I tried running this command in another windows 10 computer, and also an android device (with termux) all connected to the same router, with a resulting ping never hitting more than 50ms. I also tried to connect to another router but got the exact same result.

Given all these statements, I can conclude that the problem is from my laptop hardware (network adapter card) / software (network adapter driver (there are no suggested updates) / some faulty configuration in my internet settings / ...).

So, how can I further investigate in my issue, find the cause of it and finally fix it. Thanks for devoting your time to helping me <3 ❤

My wifi model:

Answer 1

The short example you put in shows that these ping spikes occur with a steady rate, every 8 seconds. An app like Wi-Fi Analyzer from Microsoft Store is likely to show a drastic signal drop at the same time you see a ping spike.

That kind of signal drops at steady intervals are common for certain types of non-Wi-Fi interference. Unfortunately common Wi-Fi analyzer tools can't identify this kind of interference, it's only detectable with an expensive spectrum analyzer. There's a myriad of possible sources like radio controlled doors, alarm systems, some lighting installations... From what I've seen this kind of interference tends to happen on the lower end of the spectrum.

Check your router's Wi-Fi radio settings and change it to run on a different channel. Non-Wi-Fi interference is usually very narrow band, so it normally only affects one channel.

The current setting is most likely auto. If the settings have a channel exclusion list, you can also leave it on auto and just add the current channel to the exclusion list. This prevents the radio from ever using that channel at all.

Answer 2

I have come across this issue across 3 different PCs at work and was only able to do a workaround as these are for staff working from home. These users run a phone client through the computer and whenever there is a ping spike (no timeouts), the phone line goes quiet so it cuts out (not a delay).

The workaround was to use a different network adapter so either using the LAN network adapter or use a 4G mobile broadband USB. This also has its own network adapter.

I leaning towards some Windows update causing the issue.

So still trying to pinpoint what's causing the wifi adapter connection to get ping spikes. BTW all 3 PCs are using same wifi usb on 3 different routers.

Answer 3

I had the same problem in my laptop, tried all the solutions, even changed my wifi adapter and still spikes were showing each 10 seconds. Finally the following solution worked for me, hope it works for you as well:

You need to reset and enable WWAN and WLAN services, these services are essential to run the wireless and wired connection properly. Follow the steps below:

1. Open Services (Press Windows key + R then type in services.msc then click OK)

2. Look for WLAN Autoconfig and WWAN Autoconfig> Right Click Properties and set it to automatic (If it's already set to automatic, right click then click stop then start it again)

3. Restart PC and check

Cheers!
