Hello. I have a problem that started somehow 1 month ago, or at least then is when i first saw it. My laptop seems to stutter and lag during any kind of network traffic to my laptop. At first I thought it was just happening when I was watching Youtube vids or downloading torrents but sitting there with nothing running and a simple message through skype will trigger it too. First i thought is a Laptop fault, but yesterday i digged bigger, and i noticed first it was when i used torrent. Tried to install other versions and nothing happened. Then i realized it was when i have any download traffic. Started youtube in 240p and when i make a bandwidth test everything get slow. I get frames in 240p on a Thinkpad t440p with i5 4300M, 8GB of 1600 RAM and 180 intel 530 SSD.
I really don't know what to do. I installed LatencyMon and i get this:
PS: Please, don't come with Update the Audio Drivers, or the mouse driver, or things like that. I did all these things, i even installed a fresh copy of Windows . Nothing worked. It is something that has to do with the Wireless driver, as this thing only occurs when high traffic happenes, when i download or things like that. Thanks
One thing to consider is this:
BIOS Update Utility for Windows 10 (64-bit), 8.1 (64-bit), 8 (64-bit), 7 (32-bit, 64-bit) - ThinkPad T440p - Lenovo Support (US)
It may be totally irrelevant - these issues need your personal investigation.
If you would care to search the forum for
latency
stuttering
pops
crackles
for example - you will find more examples of people using LatencyMon and trying to resolve this.
I guess, given the BIOS update, your machine is Win 10 compatible
Updating drivers yourself in Win10, for the major drivers provided by Win 10, won't help as Uncle MS will replace versions different to those he thinks are good for you unless you take special action.
Unfortunetely i can't update bios as the laptop has an superviser password that i don't know. About the drivers i can say that are still the drivers that i installed from lenovo website and i double checked, windows did not replaced them with others
Inspect the LatencyMon report - click on the Drivers and Statistics tabs looking for clues.
Check for reports of your laptop model with similar problems.
Search this forum for examples of others investigating this as suggested above.
These show there is no one fix, unfortunately.
E.g.
Some people find reverting to an older version driver may help.
There are plenty of hints about WLAN NIC drivers.
Sorry I can't be precise..
I've had similar issues myself at one time, ndis.sys is network related driver so it's either your network driver itself or other network managment/monitoring service. For me it was BitDefender's port scanning protection feature, once I've disabled that problems were gone. Try booting in safe mode this should eliminate a bunch of possible causes or narrow it down to a few as for example your antivirus won't load by default.
Wow thanks. I will try this. As a fact i use bitdefender too
Try this then, open BitDefender, go to Modules (in the bottom) > Firewall and there disable Block port scans in the network and restart LatencyMon to see if it worked, changes should be immediate.
It's some how better, but still not how it should be :Try this then, open BitDefender, go to Modules (in the bottom) > Firewall and there disable Block port scans in the network and restart LatencyMon to see if it worked, changes should be immediate.
Here are some fixes and threads I've collated:

Thank you sir. Most of them i tried. I have the latest intel driver for my wireless adaptor, the beacon is set to 100 on the router, i allways use my laptop in high performace. minimum processor state is 100%, the bios update is not an option for me as i don't have the supervisor password, i just installed the latest Intel Rapid Storage driver, and i can say it's a change, after i disabled the scan port on bitdefender too, but still i get bad numbers :
I think the best choice will be to just move back to windows 7. Never had problems with it, only the Widi didn't work everytime
