Your computer scans for wireless access points nearby every 30 seconds or so. It also updates your current connection quality, etc. this scan that it performs causes a pause, hence the spike in ping. 2 ways of turning it off: do what Kristopher said in the comments, however, the wlan autoconfig service likes to go from manual back to automatic on its own and continues scanning for wireless networks. Hence, method two, my original post which stops it.

Ok - so if you turn of these automatic checks, how does the info about wireless networks get updated so you get the up-to-date list of available WLANs, when you use your laptop outside of your home?

I updated this mini guide. You have to turn the interface back on manually.

I tried and it just says I do not have sufficient privileges. What now?

run CMD as an admin

I love you

Thanks for the great tips !! I've frustrated with my Wi-Fi and planning to set up a wired connection, try to google the fix of Wi-Fi lag spike last time and see your post. you give me to save my money for a LAN cable :D

I really hope it helped. Though I do advise you get a lan cable, sometimes it's just not possible and/or ugly. Have fun!

I wanted to make a .bat file for a while and thought that this would be the perfect little project. Link to batfile download You can see what is written in the .bat file and download underneath.

Edit: just tested this ingame and it did not work for me. Maybe it'll work for somebody else though. :)

It's still necesarry to rightclick "Run as admin".

still having strong ping spikes every 10-30 seconds or so
it happened after window update i can't figure out what's the reason, i tried reinstalling drivers countlessly...
running a tplink archer t600u nano
anyone knows a possible fix :(?

Full makes my pc crash now when ever I try turn it back on :(

I am here to thank you. I wasn't expecting to find the solution here but fuck this fucking product I shouldn't have to command line this! Anyways, thanks for the fix.

My solution is to force Windows to shut down. Pings become bearable after that, though they still drop me to 40fps. Better than the 7 fps before.

so after disabling it do i have to turn it back on?

If you disable it and restart the os, you won’t be able to reconnect to the wireless network without enabling autoconfig

Very thankful this helpped a lot but now my download speed went from 15MB/S to 300kb/s anyone knows why or how to fix ?

It really shouldn’t have any effect on it. You can always reset all your network settings for good measure.

yep fixed it by reseting

ive been having this issue for a while now and its just really annoying, when i reset network settings, it fixes temporarily, but then comes back within like an hour or 2, so i constantly have to reset my network settings. i have tried disabling this autoconfig but it always just completely disconnects me from wifi and i cant even open the wifi menu in settings or reconnect at all and it just screws up my whole pc for some reason and even just trying to open the settings app becomes supper buggy which makes literally zero sense at all, but the only way to get things to work again is to reenable it, however, the ping spikes are still there. this is starting to get really annoying, and i have been scouring the internet trying to find a permanent fix for like the past week and a half and nothing i have found has worked at all and i just dont know what to do. have a feeling this will go unseen tho considering this post is 7y old tho lol

pretty crazy that 7 years on, this fix still works. it's also crazy that this bug still exists all over various wlan devices

Thanks mate!

Jesus. 7 years later, thank you. Just finally got my ping to stop reaching 200ms to router on WiFi6.

Damn man, you’re my hero. I googled everything but nothing worked or some options were out of the question. I finally found your thread, and now my Rog Strix G513 WiFi6 connected to a 5Ghz network is running a stable 3ms from 2 rooms away. Before this it was jumping from 1ms <1ms 120ms 240ms 130ms 4ms, you get it. It was driving me NUTS. It happened out of no where, seemingly after I uninstalled McAfee Web Advisor. The laptop is 4 days young and worked fine the first 2 1/2 days. Once I started removing and disabling nonsense that is absolutely not needed (like McAfee, automatic Spotify, Windows Teams), my ping to the router started going haywire.

You’re a blessing. Thank you. You should revive this information. It is widely unavailable.

Unbelievably this 7y old post was the only thing that worked (Valorant instead of CS:GO). Found out it was a non-Valorant issue by spamming ping command at the shell.

A better solution is to use this: https://www.reddit.com/r/ShadowPC/comments/c8ippp/good_experience_with_wlan_optimizer_to_reduce/ which makes it so you dont need to toggle this on startup. Background Wi-Fi scanning options are not available on the command line afaik :/

Yep. Just chiming in. On the god damn A7000 netgear, this scan or whatever is happening every few seconds, raising the ping to 1000s of msecs. Cannot believe such a thing is still broken. Guess the WiFi usb adapters are not so common to warrant a proper way of handling this

it worked bruh, thank you very much

I was losing my mind over ping spikes that was causing issues with Teams and games. Tried a bunch of things but this post was the key. Thank you!!

Happy to hear it’s still helping people after 7 years! Unhappy to hear it’s still a problem after 7 years lol

I'm so upset that this worked lol, thanks! I wonder why this hasn't been an issue before.. (also, my spikes were every 3 seconds: 3 secs of regular ping, 3 secs of high ping, so even if it's not every 30-60 seconds this could still work for you)

Thank you so much!

I play on the attic and used to have connection via Powerline, but I started to have problems with them maybe because of their age. My parents bought a Wi-Fi but I couldn't play CS because of the ping spikes. My parents didn't want to put ethernet cables to the attic so I tought I was screwed, but you save me.
Again thank you so much, I'm very happy for real :)

Know this is 7 years old but holy shit thank you.

I don't even play CS I just got a link here from another reddit post after searching for my problem in about 700 different ways. I tried literally everything it was driving me insane. Restarting fixed it temporarily. Full clean install of Windows did nothing.

But this immediately fixed the issue. I'm really confused why this would cause the issue, but for now I'm just glad it's working.

Is there any other way to do this without turning it off and on all the time? Is there an automatic method for example

With a bit of programming magic you could have it turn off when you launch the game and have it turn on when you exit. Unfortunately games do not do this natively nor does windows. Maybe game mode? Not sure.

Ahh I see, Ill do my research on it. Thank you
