Title:
If IPv6 enabled, Wi-Fi connection is lost every ten seconds; disabling
IPv6 fixes it
Status in “network-manager” package in Ubuntu:
Fix Released
Bug description:
After the last NetworkManager update in Precise, wifi connection
resets after setting the password, so there is like 10 seconds of
connection, and afterwards it resets and a dialog asks to enter the
password again. Disabling IPv6 for this connection solved the problem.
Here are some relevant lines from the system log when the wifi
connection reset happens:
