>Synopsis: Realtek USB 10/100/1G/2.5G LAN goes active but does not pass
>traffic
>Category: system kernel
>Environment:
System : OpenBSD 7.7
Details : OpenBSD 7.7 (GENERIC.MP) #625: Sun Apr 13 08:30:20 MDT
2025
[email protected]:/usr/src/sys/arch/amd64/compile/GENERIC.MP
Architecture: OpenBSD.amd64
Machine : amd64
>Description:
Onboard NIC works, but is slower than expected. This usb nic (dongle)
lights up, and goes active, but does not acquire an ip address and does not
pass traffic.
>How-To-Repeat:
1. turn on device
2. plug network into internal nic
3. verify nic device
em0: flags=808843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST,AUTOCONF4> mtu
1500
lladdr b8:ae:ed:e9:74:d2
index 1 priority 0 llprio 3
groups: egress
media: Ethernet autoselect (1000baseT
full-duplex,rxpause,txpause)
status: active
inet 192.168.1.136 netmask 0xffffff00 broadcast 192.168.1.25
4. unplug network and plug network into device using the realtek usb adapter
5. verify device
ure0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500
lladdr 8c:ae:4c:b9:3c:45
index 6 priority 0 llprio 3
media: Ethernet autoselect (10baseT full-duplex)
status: active
6. note that there is no ip address acquired
7. plug network back into onboard nic to send this email
>Fix:
Dunno.
