Unable to access internet via ethernet/wi fi

Installed Zorin 0S 9 on Dell Inspiron B120,
Does not recognize ethernet cable is attached, will not connect to internet
via wifi either. Please advise.. Worked before as Win 7.
Newbie to Linux.

HI, and welcome! Please be patient and wait for madvinegar our resident network expert. In the meantime please take a look here:

In terms of wireless - is there a physical switch that has to be set to 'on' to turn it on? Have you enabled 'full' wireless capability in the Notebook's BIOS (wireless discoverability)? (Press F2 to Enter BIOS at Startup).

Also, in a terminal (Ctrl+ Alt+ T or Menu | Accessories | Terminal), type:

Code:

sudo ifconfig

to see if it pulls up all your network devices and post back here but DON'T include the MAC address (6 block hexadecimal code) or any ip addresses for security precaution.

(Note on use of 'sudo' command - you will be asked for your login password to elevate you to 'root' (=Administrator in Windows) - be very careful as you will not see any asterisks like you do at login - this is a security measure used with 'sudo' usage - you get 3 attempts before dropping back to standard user.

On some Dell's what should be wlan0 for wireless can be eth1 (speaking from personal experience!)

Checked bios settings, everything is enabled.
I'm unable to even use my wired ethernet connection. Keeps timing out.
Cable is good as I use it on the desktop.

I installed Zorin on old laptop which ran fine (but slow) using Win7
everything seems fine except no access to network ehternet or wireless.

ifconfig reveals:

To get the make and model of hardware, what are the results of:

Code:

lspci

ALSO.. b43 firmware not install. I think install wiped out drivers for network card and wireless card so software update via internet did not happen. How can I install drivers via USB? K

Apparently, if you cannot access the internet, this is what you should follow:

https://help.ubuntu.com/community/WifiD ... t%20access

Keep us posted!

Follow my below guide.

Download from here the b43 firmware: https://www.dropbox.com/s/n2tjz9jnj9xw5 ... ar.gz?dl=0
(I have uploaded it onto my dropbox account). (If you have ethernet connection do it on your own PC, otherwise you can download it from another PC that has internet connection, and then copy/paste it to your Zorin PC with the use of a USB stick).

As soon as it is downloaded, paste the b43.tar.gz firmware file you downloaded into your home folder.
Right click on it and select "extract here". A new file will be created named "b43".
Open terminal (ctrl+alt+T) and write the following commands, the one after the other, pressing <enter> after each one:

sudo apt-get remove --purge bcmwl-kernel-source
sudo mkdir /lib/firmware/b43
sudo cp b43/* /lib/firmware/b43
sudo modprobe -r b43
sudo modprobe b43

Your wireless should start working.

Hi madvinegar, thanks for stepping in!

ifconfig shows the eth port as being up, weird.

Run this please and provide the results.

Code:

ethtool eth0

It should look something like this.

Code:

$ ethtool eth0

post back here but DON'T include the MAC address (6 block hexadecimal code) or any ip addresses for security precaution.

The mac address isn't going to give anyone anything they can use for hacking, at most it would tell us the maker of the board.
I can understand the IP address, as if the IP address is not a private IP address than that could be used by hackers =/

On another note, did you know ifconfig is now deprecated, "ip addr" should be used instead.

To get more information without providing any identifiable information run this please.

Code:

ip route | grep default

It should look something like this

Code:

$ ip route | grep default
default via 172.20.42.1 dev eth0  proto static


We can use this information to determine if you have a global or private address. In my case I have a private address meaning I can show you my IP and it wont impact my security at all. It will also provide some useful routing information, if you don't get a response then a default route isn't being configured, likely meaning you are failing to contact the DHCP server. and being that you don't have an IPv4 address, this is somewhat likely (maybe you do have an IPv6 enabled connection, I don't know).
