I upgraded my cable modem to an Arris S33, which has a 2.5G Ethernet port. On a good day, I can measure very close to 1Gbps through my fanless Intel i7 mobile CPU-based Nethserver with plenty of CPU left. Anybody used a USB 3 2.5G Ethernet adapter? Which brand? Did you have to install a driver?
AFAIK NethServer use latest CentOS 3.10 kernel. If your adapter declare to have a driver for CentOS 7, you’re onboard.
Otherwise, you can go for ElRepo, which contains some kmods supporting severals devices, including older or newer drivers and/or adapters.
useful also for older network cards for dummy tests
pike, thank you. I haven’t decided what I want to do yet, but if I decide to add to my system, I will provide the results.
