Situation:

I have a server with Ubuntu Server 16.04 operating system. I need to connect it to the wifi network using usb wifi adapter, but I have some issues tuning that.

When I was pluging in usb wifi adapter and runing ifconfig -a I could see this information (before settings I made):

wlx000e0008833e Link encap:Ethernet  HWaddr 00:0e:00:08:83:3e  
                BROADCAST MULTICAST  MTU:1500  Metric:1
                RX packets:0 errors:0 dropped:0 overruns:0 frame:0
                TX packets:0 errors:0 dropped:0 overruns:0 carrier:0

                RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

Wifi configuration:

  • network name (ssid): developer-modem
  • password: cHc0h6qZ3Hv8wscF
  • security: WPA/WPA2
  • IPv4 address: 192.168.0.109

Information about the same network when I connect to my PC (Ubuntu Desktop 16.04 AMD64):

Network Information

Information about my modem:

enter image description here

Settings I made:

I added this script to /etc/networks/interfaces:

# The wifi network interface 
auto wlx000e0008833e
iface wlx000e0008833e inet static 
address 192.168.0.109 
netmask 255.255.255.0 
network 192.168.0.0 
broadcast 192.168.0.255
dns-nameservers 192.168.0.1 8.8.8.8
wpa-ssid developer-modem
wpa-psk cHc0h6qZ3Hv8wscF

Problem:

When I ping 192.168.0.109 (my modem) I get responses:

PING 192.168.0.109 (192.168.0.109) 56(84) bytes of data:

When I ping 192.168.0.1 (1st dns-nameserver) I get responses with error:

5 packets transmitted, 0 received, +3 errors, 100% packet loss, time 3017 ms

When I ping 8.8.8.8 (2nd dns-nameserver) I get an error:

connect: Network is unreachable

When I ping any other address (e.g www.google.com) I get an error:

ping: unknown host www.google.com

Questions:

I am not sure that everything is setup, cause I just changed /etc/network/interfaces (see changes above) and nothing else.

How to fix this issue?

Thanks for help

  • I suggest that you remove the network and broadcast ines and then do: sudo ifdown wlx000e0008833e && sudo ifup -v wlx000e0008833e Next, edit your question to show the result. I assume the password is redacted as usually the minimum length is 8 characters. – chili555 Aug 02 '18 at 21:20
  • Also, if your Desktop already has x.109, you can not also give the same x.109 to the server. – chili555 Aug 03 '18 at 16:23
  • @chili555 I removed network from /etc/network/interfaces. After running that command I got Unknown interface wlx000e0008833e – Max Mikhalchuk Aug 03 '18 at 16:27
  • @chili555 My desktop has x.109 and server has x.109 (cause I has just one modem and one wifi adapter). So I need to remove Network Interface from my Desktop to have Interner connection on Server? – Max Mikhalchuk Aug 03 '18 at 16:33
  • If you look around in the configuration pages of the modem/router, isn't there a provision for DHCP? Is there a DHCP range? x.100 to x.150 or some such? – chili555 Aug 03 '18 at 16:52
  • @chili555 Yes, there is. DHCP IP Pool: 192.168.0.100 - 192.168.0.200 – Max Mikhalchuk Aug 03 '18 at 17:26

I suggest that you change the interfaces file on the server to:

auto lo
iface lo inet loopback

# The wifi network interface 
auto wlx000e0008833e
iface wlx000e0008833e inet static 
address 192.168.0.50
netmask 255.255.255.0 
gateway 192.168.0.1
dns-nameservers 192.168.0.1 8.8.8.8
wpa-ssid developer-modem
wpa-psk cHc0h6qZ3Hv8wscF

Reboot.

Did the server connect? Check:

ping -c3 192.168.0.1
ping -c3 www.ubuntu.com
