I'm not sure I'm on the right category here, but here goes:

I have a (rather old) TL-PA4010 and two TL-WPA4220.

The PA4010 is connected directly to my TalkTalk router and the two other WPA4220s are connected to mains sockets.

My problem is that they all have different Network Names and this means that when I move my iPad or iPhone around to different rooms, unless I change the Network name, I lose the contact. 

The TL-PA4010 is namedTalkTalk1910415 and the other two are named:

TP-link_70F024 and TP-Link_ 0952EA.

How can I arrange things so that the two TP-Link names are the same as the TL-PA4010?

Thanks

Patrick
