Windows 10: Why doesn't my Windows PC have a "Large Send Offload" option?

my PC has the slowest internet speed in my home for some reason, I get around 300mbps on all other devices give or take, and with my PC I'm lucky to get 25mbps. I wanted to do a network troubleshooting that Microsoft support has provided but that seems to be the one option I cant do because I don't have the option. I do use an ethernet adapter that uses the power outlet so i don't have to run a long cable throughout my home could that be it?

Windows doesn`t start. Authomatic repair doesn`t work.

Thanks again!!

I`m sorry I had not noticed that the text on the picture was in spanish. It says that windows has replaced some damaged clusters in "name" file and "directory". Then, at the end "an unspecified error occurred (75736e6a726e6c2e 4f6)".

I`ll do it and I`ll be updating this thread when I have the report.

I ran SeaTools. These are the results:




Does it mean my HDD is useless?

 

Slow network throughput on windows 10


This seemed to work for me:

Disabling “Large Send Offload (LSO)”

Large Send Offload is a technique of improving network performance while at the same time reducing CPU overhead. Apparently it does not work very well, so it was suggested to disable it. If you would like to know about LSO, check this MSDN article from 2001 (Task Offload (NDIS 5.1) (Windows Drivers)).

LSO is an option located in a Device Manager under your network adapter, so this solution requires Administrator Privileges.

Follow these steps:
1.Open Start Menu, right-click on Computer and select Properties
2.Under Control Panel Home located on the left side of the window click on Device Manager
3.You will get a list of all devices on your machine. Expand Network Adapters.
4.Find your Network Card and double-click on it.
5.Select Advanced tab. You will get a list filled with different options.
6.Select Large Send Offload V2 (IPv4) and set the value to Disabled
7.Do the same for Large Send Offload V2 (IPv6) if it is available
8.Click OK

After clicking OK, tried to send a file over the LAN network. Transfer speed started very slow, but it was gradually picking up speed. Decided to restart the computer and try to send that file again and this time it worked like a charm.

Now that sending of files worked as it should, also checked speed for receiving files. It turned out that it was still slow but all that was needed to fix was to disable Large Send Offload V2 on the other computer. Once done, problem was solved for receiving files as well.

Hope this works for you guys / girls

 

Slow network throughput on windows 10

Made an account to chime in -- this worked for me. Speed jumped from ~3.0 MB/s to 30 MB/s.

Thank you very much
