Windows 10: Slow wifi speed with only one laptop

Hi all, im trying to fix slow wifi speed only with one laptop asus x515. All devices laptops, phones across home, connected to same WIFi have speed around 800mbps. Only one has around 20mbps when connected to WIFI, when its connected via cabel it has around 800mbps. What i tried? - update drivers - another wifi, or connect with mobile hotspot - different OS ubuntu - clean mode - checked laptop with eset, malwarebytes and ccleaner - USB WIFI ADAPTER Do you have any other ideas what can fix my problem? Thank you in advance.

Wifi speed on my HP laptop slows down after being on for a while.

Wifi speed on my HP laptop slows down after being on for a while. If I check wifi speed with other devices it is 200 mpbs. The slow down is not the modem or router. The laptop is at 30 mpbs. If I disable the wifi adapter and then enable it the laptop will be at the 200 mpbs speed agian for a while. Is there a setting that I can change to prevent the slow downs?

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?
