[SOLVED] usb ethernet adapter detected but no connection

hey guys, I have tried to connect my usb ethernet adapter but unfortunately it has no connection at all. I have installed usb_modeswitch but doesn't had done any configuration or command with it to try to solve, I just don't know what to do, and I guess that isn't a driver problem right, if it is detected and appears on sys/class/net and stuff. Thx in advance. (シ_ _)シ

Here are some logs.

ls sys/class/net >

kaneda@heaven:~$ ls /sys/class/net/

Well you had told us nothing about doing any kind of configuration, so...

If you actually used dhcpd instead of dhcpcd, that could be your problem.

Actually here is the log for dhcpcd.

btw I use NetworkManager for wireless, don't know if it can occur any conflict. Even when everything looking fine with dhcpcd I get no connection at all.

Re: [SOLVED] usb ethernet adapter detected but no connection

Yes.
But also everything you posted says that you've a lease and a route on enp0s20f0u1c2

You've networkmanager, systemd-networkd and dhcpcd (but only on wlp2s0) running.
=> Pick one, stop and disable the others (eg. NM can handle all your connections)

Then explain what makes you believe that the ethernet dongle " has no connection at all" - because that's not correct at all.

Re: [SOLVED] usb ethernet adapter detected but no connection

Well you're correct, after looking better, the problem is, the Network is not unreachable anymore, but when I send a ping, or try to browser, it begins to load forever, if I don't got an IP the ping would just stop and said that could not reach the network, I will do what you said, remove the others, and see what happens.

Re: [SOLVED] usb ethernet adapter detected but no connection

Unfortunately, I removed all services instead NetworkManager and still with problem, even with an address leased, I tried a ping and all received only packets loss

Re: [SOLVED] usb ethernet adapter detected but no connection

What did you do to remove the services exactly? You need to both 'stop' and 'disable' them and then restart the NetworkManager service. Can you ping an IP in your LAN e.g. 192.168.1.1?

I’m not on the device right now, but I suppose that yes I can, about the other services, sorry how I expressed myself, but I just done what you had said, stop and disabled. Maybe this could be some problem with DNS?

Re: [SOLVED] usb ethernet adapter detected but no connection

You're trying to ping an IP directly, so there's no domain name to resolve. So DNS shouldn't be relevant, I don't think?

About trying to ping google dns, or browsing anything.

Re: [SOLVED] usb ethernet adapter detected but no connection

When you're back on the device and preferably after a reboot:

find /etc/systemd -type l -exec test -f {} \; -print | awk -F'/' '{ printf ("%-40s | %s\n", $(NF-0), $(NF-1)) }' | sort -f
ip a
ip r
ping -c1 _gateway
ping -c1 2001:4860:4860::8888 # googles IPv6 DNS server

This is not a DNS issue for the reason cfr pointed out. There's no DNS in "ping 8.8.8.8"

Re: [SOLVED] usb ethernet adapter detected but no connection

You've carrier, lease and a route and can ping the _gateway (via IPv6)

ping -c1 -4 _gateway
ping -c1 2001:4860:4860::8888%enp0s20f0u1c2

Re: [SOLVED] usb ethernet adapter detected but no connection

ping -c1 _gateway

still works?
The traffic apparently gets dropped in the router or a firewall in the LAN.

Sanity check: does *any* device behind that router have internet connection?
Does the router have internet connection?
Log into the router and try to ping 8.8.8.8 from there…

Yep, I can still ping the gateway.

Sanity check: Yes all of them work, but they are all wireless connections, maybe is something with wired connections on the router? I will try to log into thw router and see.

Edit: For some reason it just started to work after a reboot, tbh I changed the router port that I connected the cable, and now, it just works, I will mark this as solved, THX A LOT for the patience seth, you are a hero.
