Akut-hjälp: Asus AC66U funkar ej efter flash

Here's the whole recommended method for recovery that I use myself in case of problem:

To reset the router settings:

1) Turn the router off
2) Unplug modem and every computers from ther outer except for one single computer
3) Press the WPS button, and keep it pressed
4) Turn the router on
5) Wait 10 seconds, then release the WPS button
6) Wait about 10 seconds, then turn it off

For the recovery flash:

1) Start the Firmware Recovery tool on your computer. Select the file, then click on Upload. It will start looking for the router.
2) Press the reset button, and while it's pressed turn the router back on
3) Give it about 20 seconds - the Recovery tool should then detect the router, and start uploading the firmware.

The reason I like to start the upload process BEFORE turning the router back on is that sometimes, you might have a timing issue where you start the upload too late. So long you turn the router on within 5-10 seconds after clicking on "Upload" you should be fine.
