Can't connect wifi(SOLVED)
« on: December 26, 2015, 10:40:57 am »
Hi,
Have just installed Peppermint 6 on my Grandsons laptop, Dell Inspiron 6400, this to replace his Pep 5, he was having problems following some trouble with home wifi router ( now resolved) and updates he lost connectivity. I am able to connect via wired connection but how do I connect to wifi please. A fairly quick response would be much appreciated so I can get him back up and running before new school term starts.

Many thanks in anticipation of the usual excellent help on here,

Regards,
Degsy

Hi Degsy, how's it going  ;)?  To connect to WiFi you left click on the Wifi icon on the right hand side of the panel.  Select your network connection from the list, (if it's not present, click on More networks).  Enter you Network password in the setup box.  This is usually found on the back of your network router.  If this doesn't work, have you run a post-installation update and upgrade?  If you haven't done this, we highly recommend you do so.  This often fixes many issues without the need for any further action. 

Since the time when your installation ISO was originally created, the kernel and the installed software packages will have gone through several upgrades.  Peppermint, like other Linux distributions is a very dynamic and rapidly evolving operating system.  Consequently, it needs to be kept as current as possible for optimal performance.  Please open a terminal window with the following keystrokes: Ctrl+Alt+t.  Enter the following commands into the terminal window.

TipLinux is case sensitive.  To reduce the possibility of typographical errors please click the Code: [Select] function below to highlight the contents. Click on the centre mouse button/wheel while the cursor is in the terminal window to paste the contents.

Note: For enhanced security, passwords are entered invisibly.  There is NO indication of any user input.  You may enter an incorrect password 3 times before you have to repeat the action you are trying to execute.

Code: [Select]
apt update && apt upgrade
Hit enter and enter your user password when asked.  Hit enter again and follow the on screen instructions.  After that has completed, continue with:
Code: [Select]
apt dist-upgrade
Hit enter and enter your user password if asked.  Hit enter again and follow the on screen instructions.

After the upgrade has completed, reboot your machine because it's highly likely the kernel will have been upgraded.  Check your WiFi and go through the setup process again.  You can also check for available drivers by navigating to: menu > Preferences > Software & Updates and select the Additional Drivers tab.  The search will continue for a few minutes.  When it's finished, select the appropriate WiFi card driver, if one is available.

If the above either doesn't work or is irrelevant, please run the following command in a terminal window and post the output back to the forum:
Code: [Select]
inxi -F

Connect with an ethernet cable, then open a terminal and run:
Code: [Select]
sudo apt-get install firmware-b43-installer
did wireless spring to life ?

if not, post the output from:
Code: [Select]
lspci -vnn | grep -i net
and
Code: [Select]
rfkill list
and
Code: [Select]
iwconfig
and
Code: [Select]
iwlist scan

Hi Mark,
Thank you for your help, however, for some reason I cannot even connect with a wired connection at the moment! Don't know what is going on, do you have any suggestions?
I could try completely re-installing if you think that might provide a solution.

Regards,
Degsy
Ps, not sure if this is relevant at all but it takes forever just to shut down.

gonna need the output from these commands .. maybe write the output to a text file then move it via usb stick to a PC you can post from
Code: [Select]
lspci -vnn | grep -i net
and
Code: [Select]
sudo lshw -C network

were you previously able to connect via ethernet cable ?

Also in reply to your question, yes I was able to connect earlier via a wired ethernet cable, no idea why it stopped working. As I said before it takes so long to shut down that I did do a switch off, using the on/off button.
Hope the info provided is helpful

Regards,

Degsy

does the cabled connection start to work if you run:
Code: [Select]
sudo modprobe b44
?

Hi Mark,
Tried the last command you suggested but nothing happened, the cursor blinked for a few seconds then stopped and nothing happened.
I have booted to the live cd and the wired connection is active from the live cd, does this help at all?

SAVE the file and exit gedit

REBOOT

Does the cabled connection now work ?

Since I re-installed the cable connection has worked.
Should I still carry out your last instruction?
