No Wifi [SOLVED]
« on: August 13, 2015, 10:48:43 pm »
Hi there
I am a new user to Linux.
I am running an old Dell Inspiron 6400.
The win7 was driving me crazy, so I decided to install Linux.
I heard good things about Peppermint so I went for it...Big mistake.
It took me 4 hrs to realize that your installation does not like my Kingston 8GB USB drive, So I found an older USB and finally was able to install it.
Now that the Peppermint is running, it has no Wifi, not even an icon- NADA.
I tries to use a few guides to install Driver update for the Brodcom but instead of having a wifi connection, I now lost my LAN connection (wire connection directly to my router).
Wrong foot to start my Linux experience.
I need a detailed and simple guide to connect to my Wifi, or I'm going back to Windows...!!!

Hi yaron66, and welcome to the forum :)

Can I start with - saying things like "or I'm going back to Windows" as if it's some kind of threat is not going to endear you to anyone nor prompt them to lend you assistance, you're more likely to just get a "goodbye then" .. please remember the people here are unpaid volunteers who  give their valuable time helping others because they enjoy doing so, please afford them the respect they deserve and I'm sure they'll then be more than happy to assist :)

OK, now to the problem at hand...

You're going to need a wired connection to install the broadcom drivers so you have 2 options here:-

a) attempt to fix the cabled connection first, then sort out wireless
or
b) reinstall, then sort out wireless

At this point, where it's a new installation anyway, (b) would probably be the easier option unless there's a reason not to ?

Do you want to reinstall, then come back here with a working wired connection ?

If so, once you're back here can you open a terminal and post the output from the following commands:
Code: [Select]
lsusband
Code: [Select]
lspci -vnn | grep -i netand
Code: [Select]
sudo lshw -C networkand
Code: [Select]
iwconfigand
Code: [Select]
rfkill listand
Code: [Select]
sudo iwlist scan

Welcome to the forum.

As hardware vendors do not have an incentive to support Linux, they don't always.

Please be patient during the first steps to Linux. It is not always easy to get everything working, but once it is set up it is generally a pleasure to use.

Hi There
Thanks for offering assistance.
So far- no success.
I've reinstalled peppermint 6.0
Ethernet came back to live miraculously.
I run the preferences and driver update
it recognized that braodcom driver was missing and asked to update and install it.
I confirmed, and it did, but still no WIFI.
I went to update manager
I installed all the suggested updates that apeared there, and restarted the PC.
Back to square one- NO WIFI and the Ethernet is gone as well.
So I reinstalled Peppermint for the third time.
And answering you questions:

Hi yaron66, welcome to the Peppermint Forum.  Yeah, drivers for Broadcom hardware can be a pain; they're real oddballs.  Not insurmountable by a long shot though.  Hang in there and PCNetSpec should get you up and running.  It's not the first time he's done this  ;D

In the future, could you please encapsulate terminal outputs with the # Insert Code function.  This is located in the forum editor, just above the, Embarrassed  :-[ emoticon.  It makes it much easier for people to read and preserves the original format of the output.  This time I've done this for you - many thanks and have fun  ;).

Tip: From experience, SanDisk and Lexar thumb drives have alway proved really reliable Linux work horses.

Got it working!!!
Using this guide:
http://askubuntu.com/questions/55868/installing-broadcom-wireless-drivers
That's outstanding news - well done.  Thank you for providing a link to your solution  ;)!!  For future reference, when an issue is resolved.  Could you please remember to mark a topic as [SOLVED] in the subject line of the first posting.  I've done this for you this time - many thanks  ;).
