What model switch is it? There has been some negotiation issues with a D-Link DGS-108 that are worked around in a kernel patch.
Along a similar line, I just discovered my Pi 4 won't connect with the gigabit switch here. I've done "apt-get update; apt-get upgrade" and the problem still persists. Since the same cables and switch work at gigabit speeds with multiple other computers, I suspect it is related to a negotiation problem. For the record, the switch is this
8-port model by Rosewill.
Still no luck with the 4B and the Rosewill RC-416 8-port Gigabit Green Switch. I suspect the Pi is unable to wake the ports out of low power idle which is part of IEEE802.3az Energy Efficient Ethernet.
On the Pi I tried forcing 100 mbit mode
Code: Select all
# /sbin/ethtool -s eth0 speed 100 duplex full autoneg on
as well as resetting the mii transceiver
Neither of those settings helped.
The switch works fine with the Pi 3B+ computer. However, I wanted to use the true gigabit Ethernet and USB3 of the Pi 4B for creating a reasonably quick network file server. It is good that only the 2GB model was available, because that extra pizza I was able to afford due to the resulting savings is a comforting memory at the moment.
Has anyone else tried the Pi 4B with the same Rosewill switch?
As I only have one gigabit switch at home it will be next week before I can try the Pi 4B on a different switch.
Does anyone have an idea how to make the 4B work with my gigabit switch?
