Wifi - When setting up a repeater, should it be set to repeat the same SSID on the same channel? If true, how does a PC decide which AccessPoint to connect to?

As far as I know, that's the only choice you have.  In order to talk to the 'parent', the 'child' (repeater) must be on the same channel and using the same SSID and security protocols that the 'parent' uses. I have never seen a ''repeater'' that offers to talk to the client on a different channel or SSID than the parent. Doing so would likely require 2 radios... in that case a bridge would be possible, which would double the bandwidth available over repeater mode.

Typically the repeater will offer a much-stronger signal, and that usually decides. Most 3rd-party connection managers allow you to set the roaming decisions according to different criteria; the windows WZC service does not offer roaming decision options at all.  If the computer is located about halfway in between the repeater and the parent, the decision is normally made based on which is offering a stronger signal (even though it should probably be based on which has the greater signal to noise ratio), and it may spend quite a bit of time each day disconnecting from one and then associating with the other one unless you're using a 3rd-party connection manager with which to force it to connect to a specific AP (e.g. by MAC address).

Thank you, I suspected it true but wanted to be certain, it was the only thing that made sense.
