- Go To W-FI Settings, Your Currently connected Wi-Fi /Access Point Name will be shown. - Click on the "settings" icon on the right side of it. Details of the connected Wi-Fi are shown. - Check the **DNS** IP being used. Is it the same as the **Default Route** IP? — ByronTaaka, Jun 20 '22 at 12:14
Use `ip link` to see your WiFi MTU. If it's 1500 see my answer to https://askubuntu.com/questions/1353705/ubuntu-20-04-wifi-keeps-dropping/1353723#1353723 . Your MTU should be 1492 for WiFi. — waltinator, Jun 20 '22 at 13:38
I have 3 mtu values, two of them are 1500, and one of them is 65536 — Muhammad Alaa-Eldin, Jun 20 '22 at 16:51
Please [edit] your question and add output of `lspci -knn | grep Net -A3` terminal command. — Pilot6, Jun 22 '22 at 08:00
I don't understand what should I do, I'm new to this, would you explain more.@Pilot6 — Muhammad Alaa-Eldin, Jun 24 '22 at 08:36
@MuhammadAlaa-Eldin instead of an image copy and paste text into the question That way people searching for lspci will find this and people wanting to copy your command can also do that. This site is for all not just the peiople that ask questions ;-) — Rinzwind, Aug 02 '22 at 18:24

I'd recommend that you delete the wifi connection, then re-connect.

nmcli connection delete <CONNECTION-NAME>
sudo systemctl restart network-manager.service

nmcli supports tab completion. You can find the connection to be deleted by pressing the tab

Then simply re-connect from the UI as you normally would.
