Windows 10: Slow internet with speeds of 3mbps download and decent upload of 10+

I have a new router and motem and a internet plan that is supposed to give me 100mbps but I am only getting 1-10 (download), average of 3. Some days I get stable internet speed that is what was advertised with everyone in the house using it. How ever some days in day and night it dips down randomly to like 3mbps with less people on it. When I restart my router I get smooth 90mbps for a couple of seconds.... then it drops back down to under 10 mbps.

I use Windows 10 and have a wireless adapter for my pc. My upload speeds are fine tho with over 10 mbps constantly.

Slow download speed on Windows 10

When I built my computer I only had a Windows 7 disk lying around, so I installed Windows 7; Internet worked completely fine and didn't have any issues with the download speed.
I then downloaded Windows 10 onto a USB stick and ran a fresh install (since I read that upgrade installs can cause problems); the first time round the download speed was fine, but now my download speed is incredibly slow.

This doesn't seem to be related to a current ongoing problem with the motherboard as Internet worked fine in Windows 7.

On testing the speed, I found that I get a maximum of 3Mbps download and 0.96Mbps upload:





The Internet connection is rated at a maximum of 20Mbps download and 1Mbps upload; it seems that while the download speed has been impacted, upload speed is not. When I download anything, the entire Internet connectivity of the machine is bottlenecked by the program doing the download; this doesn't usually happen as my router's QoS prevents this from happening.

Thinking that it was a driver issue, I reinstalled the driver for the Ethernet (Intel(R) 82576 Gigabit Dual Port Network Connection) with no effect. I then downloaded and installed the driver for my motherboard from the manufacturer's website, again to no effect.

I read that disabling “Large Send Offload (LSO) could fix the problem; I have done so but yet again, to no effect. I've also done the standard stuff of rebooting the router & verifying the speed with another Ethernet device.

I also ran a speed-test on my phone, and it's the normal speed (so the router or the actual Internet connection isn't the issue here):





There are also quite a few settings in the Ethernet adapter's properties; perhaps one of these could be the cause?

The settings are as follows:

 

Extremely slow internet speed on Lumia 650

Hi, I just received my new Lumia 650 today. However I found that the internet speed seems to be extremely slow. My network is 100mbps educational network. And using Speedtest software, my iPad has a speed of 90 Mbps upload and 90 Mbps download. However
for Lumia 650, it only gots 3mbps up and down load under the same wifi environment. The LTE network is also very disappointing 8mbps .so I wonder if there is a problem with my phone.

 

Slow Download Speed

Hi,

Thank you for posting your query in Microsoft forums.

• I would suggest you to test the speed using any of the speed test website or app to confirm the upload and download speed.
• I also suggest you to reset the wireless router to check if that helps.
  
• You may plug in the Ethernet cable if available and check the speed.
