How-To: Fix slow reconnection to Wireless after suspend/sleep in Linux
r3dux | March 13, 2012Every time I’d put my LMDE-running machine to sleep, the wireless wouldn’t come up for maybe a minute or so… which is both new and rubbish. So, how to fix it?
Simple: Change your IPv6 settings from Automatic to Ignore, like this:

If you’re not using Gnome 3 (like in the above screenshot), then maybe try modifying /etc/network/interfaces – really, it’ll depend on your Linux distro where the config is located.
But once IPv6 is disabled, your wireless won’t have to wait for the DHCPv6 timeout, which is the cause of the slow reconnection.
