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

    Did you notice this issue with any other device (other than your laptop) connected to the hotspot? Feb 5, 2022 at 14:27
  • Yes, also on the laptop of my girlfriend (U20.04 too) Feb 5, 2022 at 18:01
  • To be more precise, this happens also sometimes at work when my laptop is connected to the enterprise wifi Feb 5, 2022 at 18:01
  • Can you give more details about your laptop? Brand, model number, wifi chipset name, etc.? Feb 5, 2022 at 18:24

First try:

sudo ufw disable

If that solves the problem, you can do:

sudo ufw enable
sudo ufw       allow in  on wlo1
sudo ufw route allow out on enp41s0

My system works with:

$ sudo ufw status numbered
[ 1] Anywhere on wlo1           ALLOW IN    Anywhere
[ 2] Anywhere on enp41s0        ALLOW FWD   Anywhere       (out)
[ 3] Anywhere (v6) on wlo1      ALLOW IN    Anywhere (v6)
[ 4] Anywhere (v6) on enp41s0   ALLOW FWD   Anywhere (v6)  (out)

Only [ 1] and [ 2] are strictly necessary.
