I recently changed apartment and suddenly I keep loosing the wifi connection even though I do not have problem on other laptops or my phone. I saw that other persons were also experiencing that issue in the past but it usually comes with tailor made solution. I am using the last version of elementaryOS which essentially Ubuntu behind.

I am not sure what outputs I should provide but here are some.

Outputs from lspci -knn | grep Net -A2:

02:00.0 Network controller [0280]: Intel Corporation Wireless 8265 / 8275 [8086:24fd] (rev 78)
    Subsystem: Intel Corporation Wireless 8265 / 8275 [8086:0050]
    Kernel driver in use: iwlwifi

Here are some outputs from /var/log/syslog:
