Need Help Configuring New AP Express N

Question

Here's my current setup.
1. 1TB TC Dual Band (newest model)
2. 4 wireless G devices (2-Tivo's, PS3, iPhone)
3. 3 wireless N devices (2 MBP's, Mac Mini)
4. Airport Express N (AEn) (not yet configured or connected). New, still in the box.
I want to extend my wireless network because 1 of the N devices (Mac Mini) is in another couple rooms away from the TC and the reception is GREAT (5 bars), however the internet speed is poor and good (it fluctuates). Doing an internet SpeedTest it goes from 1 mbps to 14 mbps.
Questions:
1. Will the new AEn help with the internet speed for the Mini , if I use it to extend my network?
2. Will adding the AEn to my network drag down the other 2 N devices (slower network)?
2A. If yes by how much?
3. Will the AEn work in the N mode Only or Only mixed mode (a,g,n)?
4. Will the AEn cause problems with the TC because it's Dual Band?

Answer 1

1. Will the new AEn help with the internet speed for the Mini , if I use it to extend my network?
No. Using the 802.11n AirPort Express Base Station (AXn), will have no affect on your Internet connection speed. However, it should help your local wireless speed by providing a stronger signal to the Mac Mini.
2. Will adding the AEn to my network drag down the other 2 N devices (slower network)?
No.
3. Will the AEn work in the N mode ONLY or only mixed mode (a,g,n)?
The AXn is a single-band wireless router. It can operate in either the 2.4 or 5 GHz radio band at a time.
4. Will the AEn cause problems with the TC because it's Dual Band?
No. You can use the AXn to extend either the dual-band TC's 2.4 or 5 GHz radio.
