[SOLVED] Intel Wireless card connectivity Issue - Mint 15

Postby Stretchkev1 on Wed Jun 26, 2013 6:11 pm

Hi,

I recently did a clean install of Linux 15 Mint: Cinnamon, after rebooting I can't connect to my Wi-Fi network. My network pops up no problem, but after entering my password Mint thinks for a minute or two, but it fails to connect every time. t this point I don't know how to diagnosis the issue without being able to connect to the network. Any help would be appreciated.

Machine: ASUS U56E

Re: Unable to connect to Wi-Fi network after upgrade

Postby Stretchkev1 on Mon Jul 01, 2013 9:16 pm

So I have tried the following:

Code: Select all
echo "options iwlwifi 11n_disable=1" | sudo tee /etc/modprobe.d/iwlwifi.conf
sudo modprobe -r iwldvm
sudo modprobe -rfv iwlwifi
sudo modprobe -v iwlwifi


Has stopped the endless thinking, but it not keeps asking for authentication without connecting. Any suggestions?

You might wnat to run rfkill list also in case wireless is turned off on the keyboard or bios or is softblocked.

Mine as a example

Code: Select all
 $ rfkill list
0: phy0: Wireless LAN
   Soft blocked: no
   Hard blocked: no
1: samsung-wlan: Wireless LAN
   Soft blocked: no
   Hard blocked: no

My bad: double post. So I guess I will put something useful in it.

"Soft blocked" means "blocked by software". A faulty driver or other kernel module can lead to connectivity loss. So at least we know now that your problem is not a hot key switch on keyboard or a
bios setting.

Code: Select all
sudo rfkill unblock all


Then try rfkill list again to see if that took.

Since the info in INXI helped me. I found this on the forum

http://forum.linuxmint.com/viewtopic.php?f=53&t=117773
viewtopic.php?f=90&t=114978&hilit=iwlwifi

Good luck with it and Happy Trails, Rok

Edit: you might need a reboot after running sudo rfkill unblock all. I am not sure though if a reboot is needed though.

Niether of those things worked. Still shows a soft block after trying the rfkill unblock and reboot. And I can't get very far with the modify command since it keeps giving me a fatal error:

Code: Select all
FATAL: Module iwlagn not found.

FATAL: Module iwlagn not found.


That is because iwlwifi took iwlagn place as the module for your chip. Scratches head.

Maybe better? Just wondering. Why can't you just roll back to a earlier kernel? Use the shift key on power up to bring up grub menu choices.

Edit: oops. I thought upgrade meant a kernel upgrade. I see this is a clean install.

Re: [SOLVED] Intel Wireless card connectivity Issue - Mint 1

Postby Stretchkev1 on Thu Jul 04, 2013 5:43 pm

Solved the problem with a file edit to the wifi configuration:

Command:
Code: Select all
gksudo gedit /etc/modprobe.d/iwlwifi.conf


Paste to file:
Code: Select all
options iwlwifi 11n_disable=1 swcrypto=1 bt_coex_active=N


Save, close gedit, and reboot.

Thanks, I was having slow connectivity on a clean install of Linux Mint 15 MATE. I put in the options line in the .conf file and my speed is back to normal.

SOLUTION :

If you can connect to the internet with a hardline, or through an unsecured network then it is a software problem. If you are being asked for a the passkey repeatedly even after entering the correct one, it is again a software problem.

To check the block execute:

rfkill list

This command should show something like
0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
1: phy0: Wireless LAN
Soft blocked: yes
Hard blocked: no
2: i2400m-usb:2-1.5:1.0: WiMAX
Soft blocked: yes
Hard blocked: no

The problem is being caused by a software error

Execute this in the terminal window to remove the softblocks:

rfkill unblock all

And there you have it. Your password should work now.
