Thread moved to Networking & Wireless.
@rafael10: it looks like you've posted the contents of the script, and not the results.

[Vladlenin5000]

Hi, welcome.

Without other info little can be done...
There are already many topics in the specialized section - http://ubuntuforums.org/forumdisplay.php?f=336 -. Perhaps you should search for issues specific to your wifi device and OS version in the Networking & Wireless section and/or post there with informations about your hardware, namely the WiFi of course, and Ubuntu version and whether it is 32 or 64-bit.

    ======== Done ========

Please do not bump the thread in less than 24 hrs unless there is a real good reason. Other peoples' threads deserve the same level of attention as yours does.

For the problem, please try this -

1) In your router, change the encryption type from WPA/WPA2 mixed mode to pure WPA2-PSK with AES (CCMP). Avoid the mixed mode and TKIP.

2) In Ubuntu, please open a terminal, and run the following command -

sudo iwconfig wlan0 power off

Do these changes fix the problem? Or at least make the stability any better? Keep watching every 10-20 minutes the output of -

iwconfig

..and make sure "Power Management" in the output remains "off". If it turns "on" automatically after sometime, the connection may suffer again and we'll need to make it permanently "off" using other ways.

This is the script, not the report I expected. Please read the instructions carefully, as well as the prompts that appear on the terminal while running it.

And please use 'Code' tags to post the outputs. It preserves the formatting, and makes the post more readable. Please follow the "Use Code Tags" link in my signature to see how to use it.
