Hi I am also experiencing this issue sometimes. I will connect to my hotspot and things will mostly work great and then abruptly the connection will die.
Here's some info about my drivers blubee:~$ dpkg --status broadcom-sta-dkms Package: broadcom-sta-dkms Status: install ok installed Priority: optional Section: non-free/kernel Installed-Size: 14108 Maintainer: Cyril Lacoux <clac...@easter-eggs.com> Architecture: all Source: broadcom-sta Version: 6.30.223.248-3 Replaces: broadcom-sta-common, broadcom-sta-modules (<< 5.100.82.112-6~), broadcom-sta-source Provides: broadcom-sta-modules Depends: dkms (>= 2.1.0.0) Recommends: wireless-tools Breaks: broadcom-sta-common, broadcom-sta-modules (<< 5.100.82.112-6~), broadcom-sta-source Conffiles: /etc/modprobe.d/broadcom-sta-dkms.conf c5d2490e6167f876e7aae7b4f08e16e6 Description: dkms source for the Broadcom STA Wireless driver Broadcom STA is a binary-only device driver to support the following IEEE 802.11a/b/g/n wireless network cards: BCM4311-, BCM4312-, BCM4313-, BCM4321-, BCM4322-, BCM43142-, BCM43224-, BCM43225-, BCM43227-, BCM43228-, BCM4331-, BCM4360-, and BCM4352-based hardware. . This package provides the source code for the wl kernel modules. The wireless-tools package is also required in order to make use of these modules. Kernel source or headers are required to compile these modules.
