wifi drop off

[niterider]

So my wifi keep on dropping off. I have to constantly turn off and on.

The weird thing is there is no problem when I stream a radio show where it is constantly receiving 1 to 9 KiB/sec and sending a few hunder bytes/sec.

it will drop off if it is idle like I surfing the web or streaming youtube. Youtube send intermittent packets. What is the cause of this? Should I just stream a radio show and turn off the volume? seem like a waste.

Please generate an overview of your system like this:
- launch a terminal window and make it full screen, to avoid chopped lines;
- copy/paste this command into the terminal:

Code: Select all

inxi -Fxz

(if you type: the letter F is a capital letter)

Press Enter.

Copy/paste the output in your next message.

Continuous ping may helps.

Code: Select all

ping -i 5 someaddress.com

My other housemate have the same from with their wifi, so it not specific to my computer. I think this is a general wifi issue. I wonder what could cause this.

I think that the main reason is the power management.
How to permanently turn off wi-fi power management in Ubuntu

Step 1 – Check that wi-fi power management is turned on

In order to turn off the power management we first need to ensure that it is turned on.

*Open a terminal window by pressing Ctrl+Alt+t
*Now type: iwconfig and press Enter


*Type: sudo iwconfig wlan0 power off – This disables the wi-fi power management

Step 3 will show us how to make this fix permanent by firstly moving to another directory and then editing or creating (if it doesn’t exist already) the file /etc/pm/power.d/wireless

Step 3 – Making the fix permanent – Moving to /etc/pm/power.d directory

We must now move to the directory/etc/pm/power.d we do this by typing the command below into the terminal (see image below)- Note, if the directory does not exist you must create it by typing: mkdir /etc/pm/power.d

Step 4 – Creating the wireless file in the /etc/pm/power.d directory

Once we are in /etc/pm/power.d we must create the wireless file.

*Type: sudo pico /etc/pm/power.d/wireless into the terminal command and press enter, this will create the wireless file and open the file for editing as a root user.

Step 5 – Add a couple of lines of code to the wireless file, save and exit and its all done !

Now that you are in /etc/pm/power.d/wireless we add two lines of code (shown below) which tell Ubuntu to stop managing the power management of our wireless device, thus keeping the wi-fi power management permanently turned off (even if we shut down or restart the system)

*Type: #!/bin/sh

/sbin/iwconfig wlan0 power off

Now save and exit – note if you can’t find a save button (like us) just close the terminal window and restart your laptop/notebook. The changes will take effect. Also note that when you reboot, do it on battery power, reopen the terminal and type iwconfig’ and check that the power management for your wlan0 device reads: OFF.

Sit back and enjoy browsing the web and having your laptop/notebook back to its good old self, without having to have your AC cable plugged in all the time.

You need to change the driver for your RTL8192CU chipset. Like this:
