How can I force Windows to re-scan for available wireless networks from the command line?  (i.e. I'm looking for the command-line equivalent of pressing F5 on the GUI.)

I have a rooted Samsung device(system-as-root). When I open adb shell and run the dmesg  then it behaves differently for su and normal user. It throws      dmesg: klogctl: Permission denied   error when I run it without su shell.  Please suggest how can I fix this?

My university uses WPA2 Enterprise encryption for students to login their wireless. In NetworkManager I have keyed in everything that they needed   Security : WPA &amp; WPA2 Enterprise  Authentication : Protected EAP (PEAP) CA certificate is not needed PEAP version : Automatic Inner authentication : MSCHAPv2 Username and Password are correct.   Everytime I try to connect, I get a window asking me to input my password over and over again

Have reinstalled Ubuntu on my web dev server. On the old one I had an smbfs share setup to access a share over the local network to other Ubuntu boxes. It was setup using the following and worked fine -   This time round I am using cifs-utils instead of smbfs, but I presume this is fine?  Upon reinstalling the server I have been having issues making the files writable. Its mounted ok, and when from my local machine I ls -l it shows me write permissions (although from my local user), but when I goto create or save over a file it gives me a no permissions error  Here is the line in my /etc/fstab. I had to make one change to be able to mount, and I added the ,sec=ntlmv2 option, without which I was getting mount error(13)  //192.168.0.40/webserver    /media/webserver        cifs    credentials=/root/.smbcredentials,sec=ntlmv2,iocharset=utf8,file_mode=0777,dir_mode=0777,uid=1000,gid=1000 0 0   and my credentials file (unchanged from when it was previously working)  username=melon password=xxxxxxxxxxxx   How can I fix it so that I have write permissions on my mount?

I factory reset my rooted Android M phone but now I realize that there was a file in the /data directory which I need.  Is it possible to create an image (.img or something similar) of the /data partition so that I could run some recovery software for ext4 on that image? I have a little knowledge about ADB.

When it comes to , I often read recommendations like "Use adb logcat to find some more details". Looking for a good way to backup all my apps including their data,  refers to adb backup and adb restore. In several places one can find ways to remotely do on an Android device with the use of , such as transferring files using adb push or adb pull, accessing the  via adb shell, and more. So ADB seems to be a good thing to have for an Android user.  But how to get this "ADB thingy" on my computer? Not being a developer, installing the entire  seems a bit overkill. Is there a more minimalistic approach available?

I have several WiFi networks setup on my android device. I want most of them to automatically connect, but one specifically I don't want to automatically connect to. I want to manually connect to it only.  I don't want to forget it because I don't want to lose the settings for it.

I try desesperately to push an app with adb  on the /system/app folder (to install the PlayStore on my low cost tablet). So i tried to remount the /system partition with root rights :  mount -o remount,rw /system    But it give me everytimes the same response :   mount: Read-only filesystem   And i tried also with this command :  mount -o remount,rw -t ext4 /dev/block/actc /system   but it's the same thing... And i don't understand really why, even with the root user, i can't modify this...  So if someone have an idea, it could be save one person in distress :p

I'd like to move up and down available wireless access points, setting priorities as we can do in Microsoft Windows. I can't remember to have ever succeeded in this since using network-manager. Maybe something with conf files is possible...  I'm not interested in different network managers.

I'm looking for the best / friendliest way to reboot my rooted android 4.1.1 device. I found these solutions so far:   su -c "reboot" - Causes problems with wifi after restart on my device... I read that this can cause a currupt file system in some cases... Doesn't work via ssh for me. toolbox reboot - Same concerns here, but works via ssh. reboot -d 8 -f - causes problems after restart e.g. some apps wont start busybox killall system_server - "Hot Reboot" (not really a system restart) start|stop - Starts/stops Android Runtime (not really a system restart)   What is the device doing exactly when I'm pushing the (hardware) power button? I guess that's the most friendly way.

Why is one preferred over the other in this example?  sudo su echo "options iwlwifi 11n_disable=1" &gt;&gt; /etc/modprobe.d/iwlwifi.conf exit   Please provide links to Ubuntu documentation.

I'm aware there's already been  regarding Nvidia drivers, but my case is a little different. My wireless adapter's driver is proprietary, and for a minimal install, I need a command to install it. A general command for any other restricted driver that I may come across in the future would also be extremely helpful.

I've read , and carefully followed the instructions provided. I am sure the wireless card in my laptop supports going into wireless access point mode. But unfortunately, when I use the following command to start hostapd service it throws an error:   $ sudo service hostapd stop  Starting advanced IEEE 802.11 management hostapd                      [fail]    The instructions mentioned above said this could possibly be because my wireless card does not support the g mode, and provided the wiki of hostapd. But what is g mode? I tried to switch to a, or b mode, but it just didn't work.  Can anyone help with this or recommend a tool like connectify in windows ?  ps. I am using Ubuntu 12.04, 32 bit. I have an ADSL wired network, and I want to share it by setting my laptop into a WiFi hotspot with  my windows phone.

I'm a first time Linux user. My laptop wasn't connecting to the wifi so I followed the instructions from .  On typing sudo apt-get update after that, I got this error:  E: Type 'sudo' is not known on line 2 in source list /etc/apt/sources.list E: The list of sources could not be read.   What can I do?
