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). -- Vincent Lefèvre <[email protected]> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
