“I was getting intermittent dropouts on LAN connections, which turned out to be a known problem in the r8152 drivers in debian / raspbian (and other distros). What you get is random dropouts and dmesg entries:
[ 125.855442] r8152 1-1:1.0 eth0: carrier off
[ 128.564423] r8152 1-1:1.0 eth0: carrier on
[ 130.396088] r8152 1-1:1.0 eth0: carrier off
[ 133.107800] r8152 1-1:1.0 eth0: carrier on
[ 148.125673] r8152 1-1:1.0 eth0: carrier off
[ 150.963953] r8152 1-1:1.0 eth0: carrier on
I fixed it using ethtool / forcing the config in the network switch. Details are on the pi forums here:

“Nice, simple, cheap 100Mb/s Ethernet adaptor. Worked right away with my Pi Zero without the need for any software or config.
It loses a star just for the garish blue light - an unfortunate trend with cheap tech these days.
I can't comment on the USB ports as this is being used for Ethernet only.”
“Accurately described, the adapter arrived the day after ordering. It was connected and up and running within minutes following some straightforward configuration.”
“Ethernet connectivity worked first time connected to a Raspberry Pi Zero W so I can now bridge and tap successfully. USB ports work fine too (keyboard). Happy customer.”
