I have a DSL-2730U and the current firmware version shows:
Current Firmware Version: AT_1.01
Current Firmware Date: Jul 9 2015 11:08:06
I looked up the available upgrades on the DLink website and it shows three different firmware upgrade options: Files with the suffixes I1 / U1 / V1
How do I decide which is the correct firmware for my router? Any tips?
