How to fix: Android Samsung Galaxy S2 not recognized on Linux

Problem:

I was facing problems connecting my Samsung Galaxy S2 on Ubuntu, which is particularly annoying bearing in mind the total lack of support by Samsung for Linux (even Kies is of no use). Strange enough, it works flawlessly on Windows 7, where it recognises it instantly and I can transfer files between my phone and computer.
When I plug it into my Linux machine, it is recognised and I can see the contents of the root of /sdcard and the SD card but I cannot access the contents of any file or folder as all the folders are empty.
When I connect my phone to USB there is no “mount USB” option but just MTP application in the home screen. [Read more…]

How to solve: No Wireless Network Detected in Ubuntu 11.10

One of the most common problem one faces after a fresh install of Ubuntu is the loss of Wireless Network. And believe me that is the biggest pain for a normal user. The problem double-folds if the wireless adapter is broadcom (do not know what is your wireless adapter? click here). Some of the general problems are showing no wireless adapter, showing wireless adapter but detecting no wireless networks etc. [Read more…]

How to solve: No wireless network in Ubuntu 11.04 : Centrino Wireless-N 1000

Wireless and Ubuntu never go hand in hand. No version of Ubuntu has worked out of box for all wireless hardware. This post is meant for people who has Centrino Wireless-N 1000 wireless adapter. If you do not know what is the make of your hardware, follow this link: Know your Network Adapter.

If your network Adapter is of Broadcom BCM 43XX series, you may want to follow this link: Wireless problem with Broadcom in Ubuntu 11.04

Problem Detection:

Now if you are still here I assume that you have a Centrino Wireless adapter from Intel. Run the following command:

 sudo rfkill list 
1: phy0: Wireless LAN
    Soft blocked: yes
    Hard blocked: no
2: acer-wireless: Wireless LAN
    Soft blocked: yes
    Hard blocked: no

Instead of acer-wireless, there may be other result as well. If it says Soft blocked: YES that means the wireless is turned off in software. Follow these solutions.

Solution 1:

If you are connected to Ethernet (Wired Network) disconnect it and type this command:

sudo rfkill unblock all 
sudo rfkill list all

Solution 2: 

If the above command does not solve the problem. Try with this command (replace the acer with your result in previous command output ):

sudo rmmod -f acer-wmi 
sudo rfkill unblock all 
sudo rfkill list all

Make the changes permanent:

If the above mentioned solution worked then you might want to make it permanent by amending a few lines in the configuration file so that you don’t need to type these commands again and again on each boot. Type the following commands (again replacing “acer”):

sudo su 
echo "blacklist acer-wmi" >> /etc/modprobe.d/blacklist.conf 
exit

Hopefully this works for you all! Questions, suggestions and feedbacks are welcomed. If you liked the post then please acknowledge it by liking/voting/commenting on the post. Enjoy :)
