Hello all. I have a AirPort Extreme on the Middle floor of my home. It is used as my wireless provider and time machine. I am aware that I can extend my wireless network by adding an airport express. I actually get a wireless signal throughout my home but the speed drops significantly downstairs. If I extend the setup with an airport express (wirelessly) that will not boost the signal/speed ( if I understand correctly). Am I able to hardware from the AirPort Extreme into a Ethernet plug adaptor and then down stairs take another Ethernet cable from another plug adaptor and plug in the airport express? Will that give me about the same speed as I see on the Middle floor? If it's possible, will it all run off the same wireless network ( or will I end up with two wireless systems in the house)? I hope that all makes sense. It sort of does in my head. Regards Jerry.
