[Solved] Speed up slow WiFi on Ubuntu 20.04

Sometimes Ubuntu 20.04 [Focal Fossa] and the late distributions are having a slow WiFi connection speed issue, that could be related to multi factors like the old WiFi adapter being used and the not fully supported versions of those adapters, and some factors related to the WiFi module settings and the WiFi channel connection rate (2.4GHz or 5.5GHz).
Here I'm just sharing my fix and how I handled this issue, there is another solutions to be considered and you can find some on this Ubuntu thread depending on your machine and your adapter:
askubuntu.com/...
Commands used in the video:
1- sudo lshw -class newtwork -short && nmcli device status
2- sudo iwlist [your_wifi_device_name] scanning
3- sudo nano /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

Usually i dont write comments, this is probably my second comment in my life, but it helped me a lot. I had 1.4Mbit/s and now i have 59Mbit/s. Solution works on Ubuntu 22.04 aswell :} thanks !

[@YaserAz]

So glad it helped

[@alanngo268]

For those of you wondering what the values of "/etc/NetworkManager/conf.d/default-wifi-powersave-on.conf" 0: use default settings 1: ignore 2: disable power saving 3: enable power saving

[@walterorsi8552]

Thank you very much! Everybody says you have to change the value to 2 but nobody explains the meaning of the values as you've done!

[@arminshahab2836]

Thanks Yaser, You are amazing. You saved around 1000 dollar for me to not buy new laptop for the faulty internet connection in Dual boot Ubuntu 22.04 with Windows 11.

[@Shubham__Saroj]

This video is amazing, this is the issue most of the linux OS by default has. Awesome.

[@HGAr]

Thanks bro, Having the "wifi.powersave = 3" the results of the speedtest i did where: Download: 23.20 Mbps, Upload: 6.55 Mbps, Ping: 64, Download Latency: 84, Upload Latency: 104. And after changing it's value to '2' the results chaged to: Download: 29.9 Mbps, Upload: 8.39 Mbps, Ping: 21, Download Latency: 67, Upload Latency: 19. What impressed me the most was how the ping value changed from 64 to 21. Also some times the download speed gets near 40 Mbps so It really helped me a lot. Thanks again.

After typing 2 over there should we just exit? ^+x ? Pls help out new ubuntu user here.

[@lawrencecavens5760]

The other thing you can also do is research the fastest DNS server online and when you find it change your WiFi parameters setting to that new DNS and you'll gain better speed to Click on >Network Settings> select either wired or WiFi > select the little gear cog to open the settings > find the DNS section > turn off the automatic DNS and Put in the DNS server manually and once that is done save and close. you should get better results...

So if I have 2.4 frequency what should I exactly do to change the channel and how can I know that my device supports that channel. Sorry if I'm asking for to much I'm just still new to the world of tech

So is that a new internal network adapter your using or external like a USB adapter. Main reason I ask is cause we have the same default internal network adapter and I've been trying to find one thats dual band and is supported on Linux Distros.?

[@YaserAz]

The one I bought is an external USB adapter.

is there any other values that can increase the wifi speed? Also good video

[@YaserAz]

Yes it's a multi factor issue, you can check the link in the video description there are some other solutions.

[@zPrizeey]

I dont mean that, i mean like if there is another values that can increase the network speed or if 2 is the only value.

[@YaserAz]

Most answers suggested switching to 2 value, you can try switching between 1,2 and three and check the best suit for your issue.
