When I suspend my laptop the wifi disconnects obviously, however 9/10 times when it resumes from suspension the wifi is just sitting there on "authentication required" and no popup appears for me to authenticate, even turning off the wifi and back on does not fix it, I need to log out and back in for it to work.
What would be causing this and how may I fix it?
Seems this has a similar post here from the Ubuntu forums.
The Solution that seemed to work was as follows:
I have resolved the same problem very simply.
Click on Applications/System Tools/System Settings.
In the Hardware collection of icons, click on Network, then Wireless.
In the lower right hand corner of the Wireless Connected window (I earlier connected)
click on Configure…
I have Connect Automatically checked (near the top), and Available to all users checked >(near the bottom.
Click on the Wireless Security tab.
In my case for Security I have: WPA & WPA2 Personal
Fill in the Password.
Click Save.
When I restarted the system all went automatically.
