Good: A total of 5 vulnerabilities in some D-Link routers allows external access to the router bypassing and/all authentication. You do not want anyone of the 5 billion folks on the internet to have access to your home router. For some D-Link routers a firmware update to address the vulnerabilities will not be made available. If your D-Link router has a firmware update available, update the firmware.
Visit the D-Link support page, find your router, download and update the firmware.
Bad: ASUS has another problem. Phishing, Pop-up, and drive-by campaigns are offering router firmware updates that then infect your ASUS router, then the network it is protecting.
To protect your ASUS router, visit the administrator page on the router, use the Advanced or Management page to apply an update.
