I'm new to both Elementary OS and Linux on the whole. I have made a LiveUsb to try it out before installing it on my notebook. Everything works fine except for the internet. I don't have WiFi, but a wired connection. I cannot connect to the internet in any way. As I'm new to Linux I don't understand what I should do. My Ethernet card is a Realtek Lan RTL8105TA.elementary@elementary:~$ ifconfigeth0      Link encap:Ethernet  HWaddr 04:7d:7b:9f:8a:72            inet addr:10.118.14.86  Bcast:10.118.255.255  Mask:255.255.0.0          inet6 addr: fe80::67d:7bff:fe9f:8a72/64 Scope:Link          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1          RX packets:21692 errors:0 dropped:8 overruns:0 frame:0          TX packets:935 errors:0 dropped:0 overruns:0 carrier:0          collisions:0 txqueuelen:1000           RX bytes:1809988 (1.8 MB)  TX bytes:97546 (97.5 KB)          Interrupt:44 Base address:0xe000 lo        Link encap:Local Loopback            inet addr:127.0.0.1  Mask:255.0.0.0          inet6 addr: ::1/128 Scope:Host          UP LOOPBACK RUNNING  MTU:16436  Metric:1          RX packets:1261 errors:0 dropped:0 overruns:0 frame:0          TX packets:1261 errors:0 dropped:0 overruns:0 carrier:0          collisions:0 txqueuelen:0           RX bytes:84217 (84.2 KB)  TX bytes:84217 (84.2 KB)elementary@elementary:~$ cat /etc/network/interfacesauto loiface lo inet loopbackelementary@elementary:~$ cat /etc/udev/rules.d/70-persistent-net.ruleselementary@elementary:~$ lspci -k | grep -A2i net ; nmcli d listgrep: 2i: invalid context length argumentGENERAL.DEVICE:                         wlan0GENERAL.TYPE:                           802-11-wirelessGENERAL.VENDOR:                         Atheros Communications Inc.GENERAL.PRODUCT:                        AR9462 Wireless Network AdapterGENERAL.DRIVER:                         ath9kGENERAL.HWADDR:                         08:ED:B9:79:C6:99GENERAL.STATE:                          20 (unavailable)GENERAL.REASON:                         0 (No reason given)GENERAL.UDI:                            /sys/devices/pci0000:00/0000:00:05.0/0000:02:00.0/net/wlan0GENERAL.IP-IFACE:GENERAL.NM-MANAGED:                     yesGENERAL.FIRMWARE-MISSING:               noGENERAL.CONNECTION:                     not connectedCAPABILITIES.CARRIER-DETECT:            noCAPABILITIES.SPEED:                     unknownWIFI-PROPERTIES.WEP:                    yesWIFI-PROPERTIES.WPA:                    yesWIFI-PROPERTIES.WPA2:                   yesWIFI-PROPERTIES.TKIP:                   yesWIFI-PROPERTIES.CCMP:                   yesGENERAL.DEVICE:                         eth0GENERAL.TYPE:                           802-3-ethernetGENERAL.VENDOR:                         Realtek Semiconductor Co., Ltd.GENERAL.PRODUCT:                        RTL8101E/RTL8102E PCI Express Fast Ethernet controllerGENERAL.DRIVER:                         r8169GENERAL.HWADDR:                         04:7D:7B:9F:8A:72GENERAL.STATE:                          100 (connected)GENERAL.REASON:                         0 (No reason given)GENERAL.UDI:                            /sys/devices/pci0000:00/0000:00:04.0/0000:01:00.0/net/eth0GENERAL.IP-IFACE:                       eth0GENERAL.NM-MANAGED:                     yesGENERAL.FIRMWARE-MISSING:               noGENERAL.CONNECTION:                     /org/freedesktop/NetworkManager/ActiveConnection/5CAPABILITIES.CARRIER-DETECT:            yesCAPABILITIES.SPEED:                     100 Mb/sWIRED-PROPERTIES.CARRIER:               onIP4.ADDRESS[1]:                         ip = 10.118.14.86/16, gw = 10.118.0.1IP4.DNS[1]:                             172.16.172.9IP4.DNS[2]:                             172.16.172.10DHCP4.OPTION[1]:                        expiry = 1416959395DHCP4.OPTION[2]:                        broadcast_address = 10.118.255.255DHCP4.OPTION[3]:                        dhcp_message_type = 5DHCP4.OPTION[4]:                        routers = 10.118.0.1DHCP4.OPTION[5]:                        dhcp_lease_time = 2592000DHCP4.OPTION[6]:                        ip_address = 10.118.14.86DHCP4.OPTION[7]:                        subnet_mask = 255.255.0.0DHCP4.OPTION[8]:                        domain_name_servers = 172.16.172.9 172.16.172.10DHCP4.OPTION[9]:                        ntp_servers = 192.43.244.18DHCP4.OPTION[10]:                       network_number = 10.118.0.0DHCP4.OPTION[11]:                       dhcp_server_identifier = 192.168.3.1
