Slow wireless internet upon installation 12.04LTS

[radamez85]

With the upgrade to ubuntu 12.04 LTS, my internet speed is way slowed then that of my windows 7.
I have been poking around these forums looking at different threads on how to fix this issue, and have yet to find a resolution.

Please help, or can you please point me to a good thread on how to fix this issue?

Hi radamez85,

Please download the 'wireless_script' linked in my signature, run it and post back the contents (within [code] and [/code] tags) of the 'netinfo.txt' file it creates. In addition to the script's results, please also post the output of:

ifconfig

This will provide us all the initial info required to figure out the cause of the problem and possibly troubleshoot it.

If internet is slow try to perform the following :

Disable IPv6 If your internet is working Slow in Ubuntu 12.04 Precise Pangolin/Linux Mint 13/Any Ubuntu or Mint Version

Follow this to Disable IPv6, So we have to edit the sysctl.conf file.

To do this open Terminal (Press Ctrl+Alt+T) and copy the following commands in the Terminal:

sudo gedit /etc/sysctl.conf

Now add these lines at the end of file:

# IPv6
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1

Now Save sysctl.conf file and close.

Hope it helps

if it thus does not work.. then use a strong internet conection or a Lan to be sure that it is not from your service provider

Hi radamez85,

Please download the 'wireless_script' linked in my signature,

Nice script! Had to learn what 'rfkill' was. Gotz new toolz

Thanks.

Note to newbies: Take a look at the script (this or any other) and if you don't know what it does, don't run it (this one is safe) before you know what it is going to do. From the terminal type 'info [command]' where [command] is the program of interest. For instance, I didn't know what 'rfkill' did so I did 'info rfkill' to find out that the 'list' command was safe (as in this script) but others were not necessarily safe and could put you in a worse (or possibly better?) state.

Hi, the easiest way to run this script that I wrote is to run this command.

wget -N -t 5 -T 10 http://dl.dropbox.com/u/57264241/wireless_script && chmod +x wireless_script && ./wireless_script

then it creates netinfo text file in your home folder.
Thanks
