sudden slow internet speed on windows 11
anupbadri If you go to services and then search for the killer services and 'kill' them then your problems are over.

Thanks man, THAT indeed worked for me!
The earlier solutions did not work out on my systemFew people have Killer apps. This is not a solution.
- oh my, this worked, thanks!
- Killer network is not in my computer services, What to do??
mstremmelaar So what services would someone kill in Windows 11 to help the Internet speed be faster? I have Xfinity for my Internet and noticed with speed test, it's way slower than what it should be. I disabled IP v6 like someone suggested earlier. I hope someone will help me and others out with what services to disable. Thanks in advance!
- I'm not having these 😞
Tech_Lover I tried all the fixes that were suggested. Nothing worked. I don't have the Killer drivers or software. I decided to experiment. So far I have had luck by setting all my network properties to match the properties in my Windows 10 desktop. This has helped (for now) it's been about 12 hours since I made the changes and I have maintained over 200mbps speeds. Control Panel>Network and Sharing>left click on your connected Internet>Properties>Configure>Advance. I attached snapshots of the steps and 2 snapshots showing Windows 10 Network Advance Properties.
I hope this helps.
- dude thank you so much i can finally watch youtube again.
mstremmelaar of course, I love you now - works perfectly!
- Hey man, thanks a lot. This worked like a charm.
- Thanks. Did as you suggested and worked instantly. My question is tho does anyone know why this is happening?
The Reason for the Speed Problem is very Easy. On the Device Manager, select the Network Interface, right click and then on preferences. Click on Extended. Seach for Speed & Dublex. On my device the 2,5Gbs entry was selected. Go to 1.0 GBS FullDublex and the Problem is solved!!!
SidEwigk THIS WORKED, like a charm!! New PC build was fine yesterday, this morning it was very slow. Changing the adapter to 1Gps Full Duplex fixed it. Thank You!
WenchxHunter No clue. The upgrade must use generic Registry values that don't work for all. But this little tool has always fixed my problem. It simply tweaks the registry values for better throughput. Wish I had a better reason as I'm just guessing. But this always seems to happen with upgrades and some updates. Glad the fix worked for you.
In my case, I simply disabled Citrix Virtual Adapter. It seems this virtual device did not like the upgrade from Windows 10.
mstremmelaar Thanks It works for me
mstremmelaar it works went to services and stop killer
