I have a dell xps 9343 with ubuntu 15.10 ; I have a Asus RP-N53 N600 Dual-Band WLAN Repeater which I use as a wireless access point connected with a cable to my router. It used to work fine. Since a week or so the connection is not recognized anymore (not shown). My history tells me it has been 11 days ago I last connected. The wireless connection of the router itself is shown and working and other wireless connections (neighbours) are also shown. I tried deleting the connection and adding it again as if it was a hidden connection but that does not work.
The wifi connection still works fine with my android phone.
I tried: - resetting router - reinstall of broadcom drivers (PCI ID: 14e4:43b1 rev 03) using this: Installing Broadcom Wireless Drivers
but did not work.
