Connected to wifi, but no Internet. On Ubuntu.

jkilla1000 · 07-19-2014, 08:46 PM

Okay, so I'm very new to Ubuntu/Linux in general and just installed it on my desktop. For connecting to the internet I use a netgear WNA 3100. I used Wine and ndiswrapper to install the drivers for that. I followed the instructions in the ndiswrapper readme file, and connected to my home wifi. At first it let me load pages, etc, but it stopped. I tried pinging google, with no result, and being new to Ubuntu I'm not sure what to do.

Hi!

see this...

Thats not exactly what i'm looking for. The drivers are installed i just can't get an internet connection, although i can connect to wifi.

Some more information might be helpful.

What is the output of cat /etc/network/interfaces and ifconfig -a run in a terminal (you may have to run these commands as root)?

Have you tested with a wired connection? If you haven't, please do so, as that would provide valuable diagnostic information.

What type of internet access are you using (cable, DSL, etc.)?

Are their other computers in your local network that can connect to the internet?

Please be sure to surround the output of any commands with "code" tags for readability; they become available when you click the "Go Advanced" button to the right of the "Post Quick Reply" button at the bottom of the reply window.

Okay so I have the output from running those two programs, and to answer some of your questions, yes other computers can connect to the internet. And no I haven't connected the computer via wire yet.

ifconfig -a

Code:

eth0      Link encap:Ethernet  HWaddr 60:a4:4c:62:4d:37  
          UP BROADCAST MULTICAST  MTU:1500  Metric:1

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

          collisions:0 txqueuelen:0 
          RX bytes:12273 (12.2 KB)  TX bytes:12273 (12.2 KB)

cat /etc/network/interfaces

Code:

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

Your interfaces file looks a little brief. For example, this is mine with both wired and wireless connections.

Code:

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
allow-hotplug eth0
iface eth0 inet dhcp

auto wlan0
iface wlan0 inet dhcp
    wireless-essid [name_of_host]

Your netmask is 255.0.0.0? Interesting. It is usually 255.255.255.0, although I do not know enough to know if that has any significance on your system.

Just out of curiosity, why are you using Wine for your network connection?

jkilla1000 · 07-20-2014, 12:29 PM

I was using wine to extract the driver files from the installer, so that I could use them with ndiswrapper.

jkilla1000, your ifconfig -a does not show an valid ip address for a network.

It should look something like this (though wireless would be wlan0 rather than eth0)--the relevant line is in bold:

Code:

eth0      Link encap:Ethernet  HWaddr 00:11:11:a9:7d:8d  
          inet addr:192.168.2.5  Bcast:192.168.2.255  Mask:255.255.255.0
          inet6 addr: fe80::211:11ff:fea9:7d8d/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:13815586 errors:0 dropped:170 overruns:0 frame:0
          TX packets:7027093 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:2975446581 (2.7 GiB)  TX bytes:502220338 (478.9 MiB)

What wireless chipset is in this computer? (Running the command lspci in a terminal should reveal that, as long as you are not using some sort of USB adapter.) Also, what make/model of computer? Your user agent icon says Mac OS, but a) that may be another computer if the problem machine can't connect to the net and 2) the user agent icons can be mistaken.
