Bug Description

About 1 out of 3 boots on my HP TC4200, Wireless Networking is disabled upon logging in (I get an immediate notification that I am disconnected) requiring me to right click the network icon and 'enable'. I have been using 10.04 since December and this problem started happening around 1-2 weeks ago.

I have the same problem with an Ethernet connection.
Since I don't know much about network-manager internals, let's search for coincidences:
- Are there 2 connections with in network-manager? (right-click the "connection" icon, choose "Edit Connections...")
- Is your connection configured to be "Available to all users"? (mine isn't)
- What's your original installation? (mine was 9.10, gradually - and frequently - updated into 10.04)

@Flavio Yes, I have 2 connections, it isnt configured to all users, and my upgrade path has been ubuntu since Hardy much the same as yours.

I am currently having a problem with my suspend as well (logged in a different bug) where it locks up my machine with a black screen. I am beginning to wonder if the network gets disabled during a suspend and a hard reboot afterwards brings it up in disabled state? This may have seemed random to me before but it may be a pattern that I will pay attention to the next few days.

Figured out the cause of this problem.

If I suspend my laptop and it hangs for whatever reason when I try and bring it back up (happens a lot due to a different issue), I will hard reboot (hold power button down) thus causing the issue. I would guess that the suspend portion is disabling the interface somehow that prevents it from loading immediately after failed resume and subsequent hard-reboot.
