On my two wire-networked Ubuntu PCs the Network Manager icons at the bottom of my screen behave differently, although I had never noticed this until now. One flashes, the other doesn't flash.
The PC with the non-flashing icon is working OK but the PC with a flashing icon has developed a network fault. Is the flashing an indication of the fault? The fault is that the PC cannot connect to the network or Internet after boot. After doing sudo /etc/init.d/networking restart it connects to the Internet but not the network. The icon flashes both before and after the restart.
I posted about the fault here 24 hours ago but have not received any replies yet.
