I have a Linux PC with two network interface cards (NICs): one wired Ethernet and one wireless. I've set up a netplan bond configuration, which is supposed to allow the Ethernet and Wi-Fi to work together, but I'm experiencing slow speeds transferring files over Samba. Here's my bond configuration:
```yaml
network:
version: 2
bonds:
bond0:
dhcp4: true
interfaces:
- enp130s0
- wlp129s0
parameters:
mode: active-backup
primary: enp130s0
```
When I check the `ip addr`, it indicates that both interfaces are up, and the bond appears to be configured correctly. However, I'm only achieving about 10 MiB/sec when the Wi-Fi is included in the bond, but when I comment out the Wi-Fi interface, the speed jumps to around 100 MiB/sec. My expectation was for the Wi-Fi to act as a backup when the wired connection fails, but it seems to slow everything down instead. What steps can I take to diagnose this issue further?

Bonding wired and wireless interfaces isn't generally recommended due to potential performance issues. You might want to verify your setup to ensure that the Wi-Fi is indeed only being used as a failover. If they are on the same network, this shouldn't normally slow your connection unless there’s a misconfiguration. Maybe check for any issues in the bonding mode you’re using, as it may not be functioning as expected.
It turns out this might be linked to a known bug in Linux networking with bond modes. When I switched from round robin to active-backup, I didn’t realize that it wouldn’t take effect right away after applying settings. You might want to check if you’re in a similar situation and consider looking into this bug report for more context: [here](https://bugs.launchpad.net/ubuntu/+source/nplan/+bug/1746419). Maybe that can guide you to a solution!
