I often connect my laptop (U20.04) via Android hotspot (Redmi Note 10 5G).
Systematically, after a while, internet connection on my laptop disappears. In particular, the indicator shows that there is still a wifi connection with my phone, but internet is not available.
If I turn off and turn on wifi on my laptop or turn off and turn on the hotspot on my phone, the internet connection comes back, but in either case after a while the internet connection disappears again.
The settings on the phone are ok (no data limits, no power saving mode). I'm wondering if the problem is on my laptop and if there are tests I can perform in order to understand what is happening.
Thanks in advance
