Loss of internet connection over Wi-Fi in Ubuntu 10.10 ? Fix it!


Ever wondered about why frequently getting disconnected over Wi-fi in Ubuntu 10.10 Maverick? Either when you upgrade  from Ubuntu 10.04 to 10.10 or when you do a fresh install of Ubuntu 10.10 Maverick, the Internet connection over Wi-fi breaks up intermittently or in some cases degrades and breaks up after a few minutes of being connected to the web.

The culprit here is possibly Ipv6 and disabling it may fix this issue. Here is how to disable Ipv6 in Ubuntu 10.10 Maverick:

Step 1. Check ipv6 status , if return value is 0 then Ipv6 is active in your computer. Type the following command in terminal:

cat /proc/sys/net/ipv6/conf/all/disable_ipv6

Step 2. disable ipv6 by adding the following command in your /etc/sysctl.conf by typing the following:

sudo gedit /etc/sysctl.conf

and then paste the following code to the end of line.

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

Step 3. Re check ipv6 status

cat /proc/sys/net/ipv6/conf/all/disable_ipv6

and it should return 1
