Hello 

I have a little knowlegde of these things so i may soun silly. 

I have 3 X20 deco setup and using a 100mbps internet connection.  2 floor apartment. 

All decos are connected trough ethernet cable in the my network. I am quite happy with them.

I am planning to add another one in order to boost my covarage in a certain zone where we use lots of wireless. 

I will connect the new unit to ethernet again. 

What i can not decide to add a x20 or x60 ? 

will x60 give me better speeds on wireless depite my 100mbps internet speed? or should i go with a x20 ? 

there is a considerable price difference. like 1 to 1,5 on single units. 

Any feedback appritiated.
