Hello all, first post, long time visitor. I need some advice on my home network layout, and what better place to get the best advice. Anyhow, I currently live in Germany and as some may know, the house's are built with a lot of concrete. My current home is three stories, but I am only looking to get the wireless connection to the Second floor. My Current setup: -First Floor- --> Kabel Deutschland (32mb Down/2mb Up) provided modem --> D-Link Xtreme Gamerlounge Wireless Router (DHDGL4500) --> Vonage Phone Router (Phone right next to modem and routers) --> Ethernet Extender via house electrical to 2nd Floor (For AppleTV) --> iMac (Connected via Ethernet) --> Macbook Pro (Connected via Wireless) --> Airport Express connected to Bose lifestyle (Joined Network) -Second Floor- --> Ethernet Extender via house electrical from 1st Floor --> Apple TV --> Airport Express (NO SIGNAL) Additional iDevices: -iPad x2 -iPhone x2 Hopefully I've broken down my setup clearly enough. So, basically, I would like to get the wireless extended upstairs. I can't use the Airport Express on the 2nd floor to extend the wireless network because the wireless router is a 3rd party router. Here is what I haven't tried yet: -Get a switch and just split the wired connection of the AppleTV and Airport Express to extend the wireless network upstairs (Would this work?) -Just buy an Airport Extreme to extend the network properly Question: -Why, after spending $200 on the Gamerlounge Router, won't the signal reach upstairs without having to add extenders/repeaters? Thanks in advanced.
