what i know : to extend wireless range of a wireless router is to attach an access point to it.

my question is about:

SSID

channel

encryption

all of this have to be the same on the 2 devices ?

if the channel has to be different, my (Atheros) wireless card has a fixed channel no. in its settings, so how to fix that ?

Thank you.

Yes, all of that needs to be the same because the device extending your range is actually on your network.

Your card is unlikely to have a fixed channel. It probably uses whichever channel (1-11) is being used on the network that you connect to. You need to worry about the channel at the router/AP level.
