Just bouoght the unit. First Asus router. Exploring the device and turned on the AIprotection feature (Trend Micro). From what I have discovered online is I should have a place in the firmware update section to update the trend Micro signature. I saw it on a YouTube video but was not sure it was the same model. I am on the latest firmware 3.0.0.4.388_22525. Am I missing this feature? Thx.
