Wireless connection doesn't start after computer awakes frome standby mode

[J-Paul BERARD]

Network manager run normally when I start the computer with an automatic wireless connection.
If I put the computer in standby mode and I make it run again, often, I have no more wireless connection.
The command 'restart network-manager' in a terminal solve the problem
