Ethernet and WLAN connection at the same time?

[Thorsten]

Orange Pi Plus 2E, Armbian 21.02.1 Buster

I can use Ethernet OR WLAN but not both connections at the same time.

To use WLAN I have to disconnect the ethernet cable.

Do you have any idea to solve this issue?

Thanks

You cant use two different network connections at the same time as packets can only be routed to one

 gateway (usually your router or whatever device is acting as your default gateway).  If you have both WLAN and  Ethernet connected  simultaneously then the  metric with lowest value will be used:

/sbin/route
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
default         _gateway        0.0.0.0         UG    100    0        0 eth0
link-local      0.0.0.0         255.255.0.0     U     1000   0        0 eth0
192.168.254.0   0.0.0.0         255.255.255.0   U     100    0        0 eth0

 

 

The Metric field indicates the cost of a route. If multiple routes exist to a given destination network ID, the metric is used to decide which route is to be taken. The route with the lowest metric is the preferred route.
