What Zyxel downloads should I use with PLA5456?

JBrondos

I noticed that there are some Zyxel utilities such as ZyWall and firmware updater. How many of these downloads are there? How shall I use them? Are they necessary?

Hi, 

If you see there is firmware upgarde tool with PLA5456, that means you can use it to do firmware upgade.
But if you doesn't meet any problem with your PLA, then I remmand you just keep using and no need to upgarde, because PLA is the bridge device in your electric circuit and under LAN, not directly to WAN.
