This could be related to signal quality, most laptops have their wireless antenna's built into the lid. When you close the lid you are changing your signal from vertical polarity to horizontal, when you have mismatched polarity the 2 units (laptop and AP) won't be able to talk to each other.
Try tipping your notebook on it's back with the screen open and see if you still have signal, or open the lid all the way so the screen is oriented horizontal. -- wireless loses signal when closing the lid https://bugs.launchpad.net/bugs/198489 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
