Firmware version confusion...
Can anyone help me please?....i ordered two kits a WPA4220 and a WPA4220 -T, (one has an extender and a single Ethernet Port, the 4220-T has one extender and two Ethernet Ports). My confusion arises because the extenders in both kits say they are Hardware Version 3.0, but all the Ethernet Ports in both kits say they are hardware version 4. How do I check if they need a firmware update, and if they do, does the same firmware version work on both hardware versions, 3.0 and 4.0??
