Olá Pessoal!
Estou com um problema com a configuração de rede em minha máquina. Eu uso Linux Mint 19.1, após baixar o programa da Receita Federal para imposto de renda, minha rede foi desconfigurada. Eu refiz a configuração e ela voltou a funcionar, mas quando reinicio a máquina ela conecta à rede mas não navega.
Segue abaixo os arquivos interfaces, resolv.conf e grub:

INTERFACES:
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

auto eth0
allow-hotplug eth0
iface eth0 inet dhcp

RESOLV.CONF:
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
# 127.0.0.53 is the systemd-resolved stub resolver.
# run "systemd-resolve --status" to see details about the actual nameservers.

# DNS 1
nameserver 8.8.8.8
# DNS 2
nameserver 8.8.4.4

GRUB:
# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
# info -f grub -n 'Simple configuration'

GRUB_DEFAULT=0
GRUB_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0"

# Uncomment to enable BadRAM filtering, modify to suit your needs
# This works with Linux (no patch required) and with any kernel that obtains
# the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...)
#GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef"

# Uncomment to disable graphical terminal (grub-pc only)
#GRUB_TERMINAL=console

# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo'
#GRUB_GFXMODE=640x480

# Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux
#GRUB_DISABLE_LINUX_UUID=true

# Uncomment to disable generation of recovery mode menu entries
#GRUB_DISABLE_RECOVERY="true"

# Uncomment to get a beep at grub start
#GRUB_INIT_TUNE="480 440 1"

Depois que fiz as alterações no interfaces e no resolv.conf, usei o comando:
sudo /etc/init.d/networking restart

Usando o ifconfig -a tem o seguinte:
clovis@Clovis-HP:~$ ifconfig -a
eth0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500

E usando o route eu obtenho:

clovis@Clovis-HP:~$ route

Se alguém poder me ajudar, serei grato!
