Running V 220.127.116.11.100 loaded Feb 2012. Wanting to setup a 4G USB wireless modem for emergency internet access. Asus compatability list says my Sierra 320U is supported with FW V 18.104.22.168.260 So long since I have done this just checking on procedure. 1. Save my settings (In Administration) 2. Get copy of new FW and place on computer 3. Go to firmware upgrade (In Administration) and load new fw 4. Wait for router to reboot 5. Restore my settings Is that it or should I do a hard reset? Should I worry about clearing NVRAM?
