Windows 10: Internet download speed is slow on only one device in house

Hello everyone,


so 6 days ago we installed a new Fiber internet with a speed up to 100Mbps and so far its pretty good in all devices until yesterday I was downloading a game with a size of 65GB the download speed was steady at 11MB/s which is very good until suddenly the down speed dropped to 400KB/s.

Normally within the last few days when I perform a speed test I get around 90Mbps but now I get 3.5Mbps


I checked the other devices in the house all of them are operating normally and no one was downloading or uploading anything.


i didn't know what to do so I asked google and I came across a lot of solution tried all of them but the problem is not solved.


I'm using

Acer Aspire A715-71G

serial Number: NXGP9EM0017410D1813400

SNID:74105363334

Qualcomm Atheros QCA61x4A Wireless Network Adapter




Please help I'm frustrated

:)

 

Slow Internet speed on only one computer.

Hi Cody,

Slow internet speed on one of your computer could be due to the following:

• Outdated network adapter driver
• Different Wi-Fi chipset
• Computer processing speed

Make sure that the network driver of your computer(s) are always updated.

We also suggest you to contact your internet service provider for them to check your internet connection speed and give you more information.

Feel free to post back if you have other concerns.

 

Slow internet download speeds

I've got an Inspiron 7579 with the Intel Wireless Dual Band AC 3165. I have an internet connection with Spectrum Cable with a download speed of 100mbps. I receive over this amount with a Ethernet connection but only around 30-34 mbps wirelessly. I tried
several suggestions I've found but with no major improvements. I've tested the wireless in several locations in my house and even right next to the router with not much difference

Any suggestions would be appreciated or is this about what I should expect.

Thanks in advance

 

Slow Internet Over Wifi. Only Internet Speed Weirdly Slowed.

Hi, Microsoft.

Wireless Environment Details

Previously, I am using Windows 7 and upgraded to Windows 10 in my Dell laptop with overall environment details as below,

• Intel® Dual Band Wireless-AC 3165 Wifi adapter, using 5Ghz band at 433Mbps.
• Using Asus RT-AC68U, performing 600Mbps (2.4GHz) + 1300Mbps (5GHz).
• Subscribing fiber optic 300Mbps ISP speed.

Problem Statements

I am facing internet speed throttled over Wifi but not wired LAN connection. The speed throttled below than 100Mbps during downloading. The Wifi weirdly throttled the internet speed only but not local network file transfer over wireless.

Test Methods and Problem Analysis.

• The laptop and router range within 2 meters away.
• No multiple devices connected to the router during the test.
• DNS set in router is Google's DNS, 8.8.8.8
• My laptop using default Windows 10 Firewall and set network to "Private".
• No VPN were used nor installed.
• All hardwares installed with latest drivers from Dell website.
• All networking speed monitored using Resource Monitor.
• Download files from internet into laptop over LAN cable. Full speed at 300Mbps.
• Download files from internet into laptop over Wifi. Speed slowed down less than 100Mbps.
• I have a desktop PC too, using Windows 10 and LAN cable connection to router.
• Transferring files from desktop PC to Asus router and finally wireless to my laptop.
  FULL SPEED around 400Mbps.
• This is so odd. Wireless file transfer over local network can be full speed but internet over wireless slowed. Obviously not Wifi adapter problem.
• I decided to further test the router hardware.
• Download files from internet into desktop PC over LAN cable. Full speed at 300Mbps.
• Download files from internet over smartphone and tablet (both Android and iOS) wireless.
  FULL SPEED at 300Mbps. Obviously not router problem too.
• So I narrowed down the problem only can be Windows 10. Can you help me identify the problems?
