Problem with wifi connection when usb ethernet is connected

jo flag

I have a usb ethernet connection and a wifi connection. My problem is that sometimes when the usb ethernet is connected my wifi stops working and I can't use the internet anymore. How do I solve this problem? I am using Ubuntu 20.04.

I read the following posts but none of them solved my problem.

ubuntu server 16.04 wifi connection to internert lost when assign static ip address to ethernet

Cannot ping machine on ethernet while having two interfaces active (Ethernet and Wifi)

Make wifi preferable over wired connection in Ubuntu 14.04?

Internet via Wifi disconnects when I connect ethernet cable to connect a ethernet device?

UPDATE: my laptop is ASUS K555L and usb ethernet connected to a Lichee pi zero board.

Check your routing tables, before and after, with `ip route`. ReD

**Welcome to the Ask Ubuntu community.** To help us in resolving your issue, and for any members who run into the same issue in the future, can you please edit your question to include your computer's make/model (particularly if it's a laptop)? Also, you mention a USB ethernet connection. Is this a dongle that you're using, and if so, what's the hardware make/model? As you might imagine, I'm trying to rule out any known hardware issues. Thanks

I created a file at /etc/netplan/01-network-manager-all.yaml and put the following statements inside it:

auto usb0
iface usb0 inet dhcp
metrics 1

And then the following command:

sudo systemctl restart NetworkManager
I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
