I bought a 10Gbps network adapter (https://www.amazon.com/dp/B07K7SMF89) and I added it to VirtualBox as Bridged Adapter (eth2) following the official documentation: https://openwrt.org/docs/guide-user/virtualization/virtualbox-vm
The problem is that the OpenWRT read the adapter only as 1000Mbps and not 10000Mbps
root@openWrt: ethtool eth2 Settings for eth2: Supported ports: [ TP ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Supported pause frame use: No Supports auto-negotiation: Yes Supported FEC modes: Not reported Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Advertised pause frame use: No Advertised auto-negotiation: Yes Advertised FEC modes: Not reported Speed: 1000Mb/s Duplex: Full Port: Twisted Pair PHYAD: 0 Transceiver: internal Auto-negotiation: on MDI-X: off (auto) Supports Wake-on: umbg Wake-on: d Current message level: 0x00000007 (7) drv probe link Link detected: yes root@openWrt:~#
What can I do to use the full throughput? Maybe I can edit the Adapter Type?
Thanks in advance for all suggestions
