Hi everyone, May be a silly question about extreme! Just bought one and need to know a few things. 1, whats the best way to find out if the one I bought is the new 5th gen? 2, on the back of the box it says "dual band" is that simultaneous dual-band? I set the extreme up today and everything works great but I though it would give out 2.4 and 5ghz without me doing anything, when looking I had to tick a box that said 5Ghz and then the AP gave out two different WiFi names e.g. wireless LAN and wireless LAN 5Ghz. Is this normal? Would someone have to select the different network or would the device just select the correct one?
