IPv4 specific issue with USB tethering between my Debian laptop and my phone
Hi,
When I use USB tethering between my Debian/unstable laptop and my
Samsung Galaxy Note10+ phone (Android 11), everything is OK with
IPv6 connections (e.g. "wget -6"), but IPv4 connections freeze
(e.g. "wget -4" or "ssh -4"). I can notice this in particular when
testing with the same remote server. For instance, with "wget -4",
a few dozens of KB are downloaded, then the connection is completely
frozen.
I don't have any issue with the mobile hotspot (thus wifi between the
laptop and the phone) or with a Cosmo under Android 9 (instead of the
Samsung Galaxy Note10+), but in both cases, this is much slower, and
I sometimes get wifi disconnections.
On my Debian laptop, I'm using NetworkManager (nmcli).
