LinuxQuestions.org - [SOLVED] Wifi blocked.

- Ubuntu (https://www.linuxquestions.org/questions/ubuntu-63/)

- - Wifi blocked. (https://www.linuxquestions.org/questions/ubuntu-63/wifi-blocked-944777/)

So I was using my Linux box just fine with no issues. Up until I upgraded. I am running 11.10. I tried removing various modules and rfkill unblock all. As well as various other commands and tricks I could think of. Nothing worked. So, I reinstalled and the probelm went away until I Updated my system. Then the problem came back. When I reinstalled my system, I piped the contents of lsmod to a txt file and have compared the new results with the old.

Here are the old.
The asterisk means unchanged. The greater than sign means the amount of user(used by) has changed.

I do not want to have to reinstall my system to be able to use wifi. Can some one please help me out? Thanks!

I am running Ubuntu 11.10 on a Compaq Presario. 32bit, AMD CPU.

Hi amboxer21, Welcome to LQ. What exactly is the problem with your wifi? Is the card not configurable, is it up and not connecting to the AP, or is it not coming up at all, not recognized? Does the wifi led come on? Have you tried the wifi switch or keystroke combination on the machine to activate or turn on the wifi?

Please post the results of the following:

Code:

$ sudo ifconfig -a

$ sudo lspci -v | grep -i net

Good luck. ;-)

hey @ , Sorry I figured the name of my post said it all... Wifi blocked. So, Eth0 works no matter what, but after the upgrade from 11.10 to 12.04 my wifi stopped working. I toggled the switch. tried removing various modules. The only thing that seems to work is a re-installation of 11.04. Something in the new updates is doing it. Thanks Also please reread my first post.

here is the output of rfkill

Code:



root@blah# rfkill list all

the wlan0 interface is available just soft blocked. I have

I opened up the bottom of my computer and removed my wireless adapter wires then checked

rfkill list all and received:

Code:

THEN, removed the adapter from my PCI-x slot all together and still received

Here is a photo of my wireless icon menu
Attachment 9711

If I click on the enable wireless option, It closes the menu. I reopen it and the option has no check next to it.

So, it doesnt matter if the adapter is in or not. Which I "assume" means that I am missing the wireless driver!?

I have 3 hard drives. I am reinstalling a fresh copy of Ubuntu 11.10 with a wired connection so the installation will download/install the proper wireless drivers, firmware, etc. Ill comb through the necessary files and see if I can find the difference and what is missing, blocked, wrong, etc.

I've even ran through the modprobe blacklist.conf

This is such a pain!!

Even after the new installation, 3rd party sources enabled, with a wired connection... Still no wireless. WTF?

I went back and read the thread again.
1) At any point after the upgrades did you try toggling the wifi switch or keystoke combination to enable/disable the wifi?

2) Did you have a look at your bios options for wifi? I ask because one of the new drivers added is the ath3k module which is a bluetooth driver and some laptop models (my Dell Studio) have only one switch for both cards.

3) Do you have any wifi cards you can try other than this card, a usb card possibly?

Good luck. ;-)

I am so ****ing pissed right now!! I have tried everything. This has even carried over to the internal 250GIB Sata HDD with Windows 7. This happened before and I had to disconnect my linux hdd and factory reset my windows 7 hdd. Then re-install Ubuntu. I am beyond ****ing furious!! I'm moving to another distro! **** Ubuntu!

On top of it, my dumb *** ****ing android keeps auto correcting me and I'm going to smash it with a brick!!!!!!!!!!!

[sarcasm]What check the wifi toggle button? You mean the thing with the wifi icon on it? No, I never thought to check that. [/sarcasm] Sorry to be a jerk but I'm pretty mad and your asking a question that makes me feel dumb!! I of course checked the wifi toggle button bro. I'm not 12 or new to computers.

No other wifi cards or usb dongle.

I just updated my kernel to 3.3 from 3.2 after dist upgrade and it made my computer hang before the login screen. Just a purple screen. No password login UI.

I'm going to proceed with the steps I have specified then download arch Linux, or some debian variant. Screw this bro!

enabling the combo(wifi/bluetooth) did it. I did a factory reset, then enabled. I am sure you could just enable without a factory reset. I didn't think of that until after though. There has to be an easier more straight forward way! A Linux approach.

So, I assume the enabling of the combo toggle thingy installed or inserted the proper firmware/modules. It then carried over to Linux.

Glad you got it sorted.

Good luck. ;-)
