I have been running happily with WiFi on an HP 255 G3 laptop since installing Mint 13 10 day ago. Suddenly today I have no WiFi Connection and the 'Wireless Connection' has disappeared totally from 'Network Connections' accessed by Adminstration->Network! If I go via the icon on the bottom panel it tells me I was last connected to the DrayTek earlier today. I have tried installing the driver (as originally done during installation) to no avail and am unsure where to go now! mintWifi gives:-

Hello, MichaelJohn.

Please, open a terminal window. Execute the following commands and post the complete screen output for each command here.

Concise sysem overview including the network interfaces, their states and the drivers in use:
Code: Select all
```
inxi -Fxz
```
Is any wifi adapter blocked, soft or hard?
Code: Select all
```
sudo rfkill list
```
(It will not kill anything, only "list".)

Cheers,
Karl
