wireless-AC 7265 5x slower in Windows 10 vs Linux Mint 17.3

[kken2]

my old laptop has a atheros wireless chip inside.

my current laptop has an intel 7265. latest drivers installed.

Both are synced with the router at 150mbps.

From the same position on my desk, same TPLINK wr841n N-router, same modem, downloading the same speed test file ..... http://speedtest.choopa.net/1GBtest.bin http://speedtest.choopa.net/1GBtest.bin

The intel only gets 700K/s, while the Atheros gets 2900K/s

With 8 parallel threads, I can't even max out my internet connection with the Intel. I get 5300KB/s.

With 2 threads, the Atheros gets 5300K/s, and 3 threads maxes out my connection at 7MB/s.

Why does the Intel run 4x slower than the atheros? It feels like the Intel is capped.

It's consistently slower. Single thread performance is terrible.

For example, downloading Nvidia driver package, the Intel only does 3.6MB/s, whereas the Atheros maxes the connection out at 7MB/s. The Atheros could probably go faster if I had a faster broadband connection.

How can I get the Intel to perform similarly to the Atheros

I already have the wireless on max power setting in Power options.

What settings and hacks do I need to implement?

throughput booster setting does nothing

Installed the latest driver.

still the same garbage speed 600-700 KB/s for that speed test file.

and linux gives me 3-4 MB/s for that same test file.

Next I'm going to try to install Windows 7 on a usb drive and see if I get the same garbage download speed

link626,

Please let us know the results as soon as you try it with Windows*7.Best regards,Aleki

Ok, I did a fresh install of Windows 7.

I'm able to get the same fast speed in windows 7 as I am in Linux Mint. 3-6 MB/s !

I don't know why singlethread download speed sucks so much in Windows 10.

All the settings are exactly the same as in Windows 7. In windows 10, the wifi is also synced at 300Mbps, but the test file is still only downloading at <700 KB/s.

Does Windows 10 have some other special settings that might be throttling the speed? like different default registry settings?

I have both bluetooth and location turned off too.

Here's Win7 vs Win10. There is up to 10x speed difference.

I don't know what I'm doing, but I ran a command in windows 10 powershell with this output....

link626,

Windows®10 is a powerful OS full of new features and speaking about features, it comes with one called https://support.microsoft.com/en-us/help/12446/windows-10-update-delivery-optimization-faq Windows Update Delivery Optimization (WUDO), and it is initially designed to help users to get faster software updates.

This feature works a lot like torrents work. A computer running Windows®10 is used as part of a peer-to-peer network to deliver software updates faster to others, each computer distributing a little bit of the files across multiple computers and helping everyone download updates quickly.

This method seems to use bandwidth in the background. Disabling this feature may help improving the speed. Here is how you can do it. However, to learn more details about it, we recommend to contact Microsoft* for additional support.

To turn off this feature, follow these given steps:

1. Got to Settings in the start menu

2. Search for Updates & Security

3. Under Windows Update, open Advanced Options

4. Under Choose How Updates are Installed, select Choose How Updates are Delivered

5. Disable the toggle under Updated from More than One Place

Additionally, you might want to take a look at these online solutions as they may contain information that might help you improve your experience.

I completely reformatted and reinstalled Windows 10 from scratch.

This solved my problem.

I wish I didn't have to do something so drastic to fix an issue, but it was the biggest time saver in this case.

Something indeterminate was causing singlethread download speeds to suffer, and even uninstalling and deleting all the wifi drivers didn't help.
