I got the TL-WR820N router today (which isn't listed in the model list above!!! so I selected WR840N sorry for the misdirection). When I tried to set it up as repeater I didn't see any option for that! In my other routers there's a simple option for that but this one doesn't have any option.

Am I missing something here? Does this model doesn't support repeater feature? Here's a screenshot to my router settings.
