Windows 10: WiFi Internet Speed is slow. I can restore it to very good, but after shut down it becomes...

So the problem is that I get 1-6 mbps by Speedtest, but it should be 100 mbps.
I have Asus K501UQ, with Intel Dual Band Wireless AC-7265. After uninstalling the device's driver windows installs the most suitable driver, I connect to my network and get my 100 mbps. BUT when I shut down my laptop it shows me previous 1-6 mbps.

I have the same laptop with the same wireless card and it shows the same results.

Booting with Ubuntu LiveUSB is OK, solid 100 mbps. Then I boot to Windows and it gives me the same solid 100 mbps. But after a while 1-6 mbps.

My iPhone SE always give me 40-50 mbps, in the time when my laptop shows 1-6 and 100 mbps. So I don't think it's the router or provider's issue.

I can't even understand how to google this problem and can't say, whether it's adapter's issue or WIndows. How can I check where the problem goes from? Maybe some tips? It's very annoying.

Quick note: Sometimes, when you go to "update & security" and force to update windows, it downloads something, intalls, then reboots and speed shows you 100 mbps. If that's the problem (that windows is always downloading updates) then why it's doing it every day delaying my workflow?

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?

 

Windows 10 Home - WIFI Slow internet speed - limited

Hi,

I Have installed on my brand new laptop windows 10 Home "already updated", I have a 10 Mbps internet connection but only reaches 1.2 Mbps, I ran a speed test on my phone that uses the same WiFi and is reaching 9 Mbps. Something is limiting the bandwidth
almost in 90% of its capacity, WiFi driver is Updated and I'm sitting next to the modem to get a better signal strength and I get full signal bars but the speed still the same, I already tried some basic troubleshooting suggested by Microsoft but still does
not work, I don't think something is consuming the bandwidth because my phone gets a good speed. I don't know what else to do.

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.
