Slow WiFi connection - Ubuntu 18.04

[gitsad]

Hi,

I've posted here ealier: https://ubuntuforums.org/showthread.php?t=2392862 .
It was successfully resolved but still I have one problem with WiFI.

I have two OS on my laptop: Windows and Ubuntu. I have done speed test on both. Here is the results:
Ubuntu
Download: 3.68 Mb/s
Upload: 6.83 Mb/s

Windows
Download: 109.94 Mb/s
Upload: 30.22 Mb/s

As you can see the difference is enormous. I have tried every solution from this page https://itsfoss.com/speed-up-slow-wi...ection-ubuntu/ which could be connected with my problem. However, nothing has helped.

Here is my network controller

02:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8821AE 802.11ac PCIe Wireless Network Adapter

Every help would be appreciated. Thanks!

Lets check

echo "options rtl8821ae swenc=1 swlps=1 fwlps=0 ips=0" | sudo tee /etc/modprobe.d/rtl88821ae_options.conf

Reboot

It doesn't solve slow connection. Still the same .

Please run the wireless script from the sticky thread and show the outputs

Could you be more specific? What are wireless script and sticky thread ?

Open a terminal (Ctrl+Alt+T in Ubuntu) and use the following commands one by one:
sudo su
echo "options ath9k nohwcrypt=1" >> /etc/modprobe.d/ath9k.conf
Restart your computer and you should be good to go

Hello amvitty and welcome to the forum, what you told this user to do will not work, the command you posted is for devices that use the ath9k driver and the OP of this thread does not have that device, before giving recommendations you must first now the device that is being used and do research to see what is most likely the cause of the users issue.

Thanks

Oh right, thank you @praseodym for your help. I have done the wireless script. Here's the output: https://pastebin.com/YWU7jthq
