WIFI not working on Mint 17.1

[seavagabond]

Hello,
I had Linux Mint 15 Cinnamon installed on my laptop, which was new at the time, and the internal WIFI only worked if in the immediate vicinity of a WIFI.
So I bought the following external WIFI that worked fine:
Realtek RTL8723AE PCIe Wireless Network Adapter (Realtek ASUS EZ)

I installed recently Linux Mint 17.1 and now neither of the two WIFI work at all.

Can anyone advice please?

Step 1

Code: Select all

echo "options rtl8723ae ips=0 fwlps=0" | sudo tee /etc/modprobe.d/rtl8723.conf

Reboot and see if it is better

Step 2

Code: Select all

sudo apt-get install linux-headers-generic build-essential 

Code: Select all

wget https://www.kernel.org/pub/linux/kernel/projects/backports/stable/v3.19-rc1/backports-3.19-rc1-1.tar.gz

Code: Select all

tar -zxvf backports-3.19-rc1-1.tar.gz

Please run these commands in terminal and post the output to see if correct drivers are loaded for your hardware, and to make sure that wireless isn't blocked for some reason:

Code: Select all

inxi -N
rfkill list

It will also include the internal wifi, maybe that one can be fixed as well (ie for Atheros wireless, the fix for better signal strength is easy).

Hi,
Thank you for the help.
I run the commands suggested by JeremyB but there has been no visible change.
This is the outcome of the commands suggested by AlbertP:


francesca@zoostorm ~ $ inxi -N
Network: Card-1: Realtek RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller driver: r8169
Card-2: Realtek RTL8723AE PCIe Wireless Network Adapter driver: rtl8723ae
Card-3: ASUSTek USB-N10 802.11n Network Adapter [Realtek RTL8188SU] driver: r8712u
francesca@zoostorm ~ $ rfkill list
0: hci0: Bluetooth

Hard blocked: yes

It's hard blocked.... Try this:

Code: Select all

sudo rfkill unblock all

You might also try to unblock by using the Fn key combination on your laptop for that. Or there might be an option in the BIOS of your laptop, which allows you to set the wireless to "always on".

What model computer is it?

It works!
I can use the internal WIFI, at last!
