I have an Realtek Semiconductor Co., Ltd. RTL8101/2/6E PCI Express
Fast/Gigabit Ethernet controller (rev 02) Subsystem: Acer Incorporated
[ALI] RTL810xE PCI Express Fast Ethernet controller
There is also a Realtek Semiconductor Co., Ltd. Device 8161 (rev 15)
Subsystem: Realtek Semiconductor Co., Ltd. Device 8168 100BaseT not
being used.
lspci -v says the driver is R8169 for both.
firmware-realtek is installed and does not appear to provide R8169 but
I'm a novice about these things.
The cable leading to the debian computer, when connected to a different
computer, runs at almost 1000 Mb according to iperf3.
When talking to Debian Buster it runs about 100Mb give or take.
ethtool says its running Speed: 1000Mb/s Duplex: Full
I just noticed this - in the past it ran at 1000Mb/s rates. It may have
happened when I recently went from squeeze to buster, but I can't be
sure of that.
Any suggestion on how to proceed.
