Extending WiFi coverage

[Humpty]

Hi All,

I am sure this has been covered many times but despite googling and searching these forums I still haven't been able to find details on the right solution for me.

I am wanting to extend WiFi coverage but do not have the option to route network cable so it has to be wireless.

So, my questions is, if I purchase a WiFi repeater does the repeater have to have a separate SSID or can I have one SSID that devices will always connect on?

Thanks in advance for any pointers.

Thanks both, much appreciated. If the SSIDs are set to the same should they also be on the same channel?

Great. Thanks for the confirmation.
