Problems with Wired Connection Configuration

Postby lusvelt » 2020-11-01 11:27

Hello everybody,
I've been struggling with this problem for a while. I have performed an installation of Debian 10.6.0 on my 64-bit machine (dual boot with Windows 10), and during the installation (netinst) all went ok (DHCP configured, got IP address, downloaded from the mirror, etc.).
However, when I now boot into Debian, the wired won't connect. A notification appears which says "Activation of network connection failed".
I disabled Windows fast startup option as some website stated for solving the problem, but nothing.
This is my lshw output for the Ethernet interface:
Code: Select all
*-network
             description: Ethernet interface
             product: Ethernet Connection I217-V
             vendor: Intel Corporation
             physical id: 19
             bus info: pci@0000:00:19.0
             logical name: eno1

             resources: irq:24 memory:f7f00000-f7f1ffff memory:f7f39000-f7f39fff ioport:f040(size=32)

The interface seems not to be taking an IP address, so there may be something wrong with DHCP. But DHCP is well configured and working if I connect via WiFi. This is the output of ip a:
Code: Select all
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: eno1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 74:d0:2b:a2:63:bb brd ff:ff:ff:ff:ff:ff
3: wlp3s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
    link/ether 24:0a:64:10:d6:48 brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.69/24 brd 192.168.1.255 scope global dynamic noprefixroute wlp3s0
       valid_lft 20722sec preferred_lft 20722sec
    inet6 fe80::5e8a:8604:14d9:ad06/64 scope link noprefixroute
       valid_lft forever preferred_lft forever

If I try to assign a static address to the interface it seems to be connected, but the network is not accessible. This is the output of ip a when I use static configuration:
Code: Select all
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: eno1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 74:d0:2b:a2:63:bb brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.2/24 brd 192.168.1.255 scope global noprefixroute eno1
       valid_lft forever preferred_lft forever
    inet6 fe80::40ec:3796:ca3e:7968/64 scope link noprefixroute
       valid_lft forever preferred_lft forever
3: wlp3s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
    link/ether 24:0a:64:10:d6:48 brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.69/24 brd 192.168.1.255 scope global dynamic noprefixroute wlp3s0
       valid_lft 20494sec preferred_lft 20494sec
    inet6 fe80::5e8a:8604:14d9:ad06/64 scope link noprefixroute
       valid_lft forever preferred_lft forever

But if I switch off the WiFi connection and I ping 8.8.8.8, I get no response. Even if I ping the gateway (192.168.1.1) I get nothing.
The routes seem to be fine, as this output of ip route list shows:
Code: Select all
default via 192.168.1.1 dev eno1 proto static metric 100
192.168.1.0/24 dev eno1 proto kernel scope link src 192.168.1.2 metric 100

I tried to reinstall Intel I217-V drivers, but nothing. I really have no idea on what I may be missing.
I would really appreciate any help.
