Bug Description
I found a few similar bugs in launchpad history but they are at least 3-4 years old, and I encounter this problem just after upgrade to 12.04!
I consulted a colleague who is a network expert, he suggested me to stop using wireless mouse, adjusted router settings, such as changed channels, added mac address binding, stopped ssid broadcasting, just in case there are some hackers trying to attack my network, but to no avail.
Their are still possibilities of hardware configuration, environment issues or hackers around my house, but the most strange thing that triggered me reporting this bug is that all my other devices like windows laptop, android phones are all OK, only this Ubuntu laptop having problem!
I also attach 2 files, one is the output of a ping command so that you can see what happened (during the ping session I tried to let network manager reconnect, even if it reconnected, the network is still not pingable.
Another file is syslog about the network manager.
