I had some problems to get the wifi connection work on my Dell Latitude E5400.
I could easily create the connection to my wireless LAN via the network manager applet, got an IP but that was all.
I could not ping any other network device or access the internet.
Finally I found some kind of solution: When I disconnect (apparently important to do that first!), unload the iwlwifi &
BCM4313 chip on my laptop. When using the Broadcom STA (wl) driver, wifi connects successfully to the Netgear N150 router but when I ping the router (192.168.1.1) it says Host Unreachble. If I connect to any other wifi router like D-Link or Linksys (or even tethered android phone) everything works fine.
