wifi problem

Post by MZippy »

Good afternoon,

I installed Mint on a Dell D420 and all is great apart from that I cannot get wifi to work. It connect fine via cable but no wifi.

I tried:

* Switching wifi on - nothing happens
* Downloading drivers from Dell - no joy.(Maybe I haven't installed the driver properly?)
* Going to the menu item "Window Wireless Drivers - ndiswrapper driver installation tool" which asks for a inf file at which point I draw a blank.

Any help would be greatfully received.

Thank you caf.

For this simpleton, please confirm what it is I have to do. Do you mean that I go into the command prompt and just type "lspci -nnk | grep -iA2 net" and then post the result?

Open a terminal and use your mouse to paste that in
Hit enter

Copy the result here.

Typically Dell use broadcom but they are not all the same. The output will tell us what we need to do to get the correct firmware for your wireless

Make sure you are connected to ethernet
Open a terminal
Paste this and hit enter

Code: Select all

sudo apt-get install firmware-b43-installer
Once it's done, reboot.

Wireless should work.
If not report back

Thanks.
I pasted and entered then it asks "[sudo] password for mark"
I try to enter passwrod but typing does not work so i try to copy/paste the passwrod in but pasting does not work. It seems nto to let me write anything more in terminal.
Trying again, I opened terminal again and tried typing something which worked. So I deleted my typing and pasted your command. which worked but it asked for the passwrod again and would not let me type anything.

What am I doping wrong?


****Holld the rpley...tried again and seems to work. Just about to reboot.....*********
