[arch-general] Network issue with broadcom-wl-dkms

Hi everyone, I have some issues with my wireless. It is capable to connect to a network (with a static IP address) but when i launch a application which network, my laptop froze. The last driver version is installed with dkms (I removed all other versions). My laptop is the Dell XPS 13 (2015), I uses linux-lts. Any hint will be appreciate, Thomas
