I hope that you understand that the 'archive' can only go back as far as the current data stored in the logger when you first connected it to weewx. Even if you previously had it connected to Weatherlink, weewx has no way of accessing any older data. How far the logger's data goes back in time depends on the 'sample frequency' you last set. For a 5 minute sample frequency, the logger will save data for a bit over 5 days before the oldest data starts to be overwritten by new data. For higher and lower 'sample frequencies', the time will be correspondingly shorter or longer.
