Windows 10: Slow Wi Fi speed

I have Windows 10 on my DELL Inspiron 2020 PC. When connected to the router using the LAN cable I get very good download speed. However when I connect using Wi Fi the speed is very slow.

My drivers are updated.

What should I do ?

WI FI SPEED SLOW DOWN AFTER UPGRADE TO WINDOWS 10

I have wi-fi router having Ethernet as well as wi-fi port, on LAN internet speed is good i.e. same as win 8.1. But on WI-FI port internet speed is slow down.

I have Macfee Antivirus i.e. came along with Laptop.

 

Extremely slow speeds on wi-fi (win10)

I'm having a lot of problems with win10 lately... Now my speed connection sucks! I can get more than 3mbps on Wi-Fi.

1- Checked router- OK

2- Internet speed on iPhone: 305mbps

3- Internet speed on iPad: 298mbps

4- Internet speed on PC (hotwire): 395mbps

5- Internet speed on PC (Wi-Fi): 3mbps

First device manager said I had the latest driver for my network adapter - Qualcomm Atheros AR9285 - wrong!!

I found a newer version and reinstalled the hardware with the new driver (8/1/2017) but speed is still slow as my old dial-up.

Any advices out there?

 

WI FI SPEED SLOW DOWN AFTER UPGRADE TO WINDOWS 10

When I have Windows 8.1 OS, I am getting full 8 MBPS speed on WI-FI as well as on LAN.

I tried with my friend Laptop having OS Windows 7, on that laptop I am getting full WI-FI speed i.e. 8 MBPS.

I also tried with Cell Phone, WI-FI speed is getting 8 MBPS.

As per your suggestion I checked WI-FI speed by disabling Anti Virus. but problem remains same.

When I search on google for this problem it is observed that lot of users facing such type of problem, many of them revert back to Original OS.

So I need solution.
