The first thing I would try is disabling IPv6.
Please do not post pictures of terminal outputs.
If disabling IPv6 does not help, then try disabling your wifi's power saving features.
Run the following command to auto-generate an iwlwifi driver options configuration file in
echo -e "options iwlwifi power_save=0\noptions iwlmvm power_scheme=1" | sudo tee -a /etc/modprobe.d/iwlwifi.conf
Reboot after the creation of the configuration file.
If the new iwlwifi driver options file produces no improvement after rebooting it may be deleted, as on a laptop battery life is a concern.
