So, the modem is in one room with an ethernet cable connecting the garden cottage. When connecting the ethernet cable directly to a device (Xbox, laptop etc...) it gets internet connection. When however connecting an access point and then wirelessly connecting to the access point there is absolutely no internet connection. I have actually replaced the access point thinking that is the problem... Still no luck. Actually took the AP to the modem and used a different ethernet cable. Miraculously the wireless connection works. I'd love some advice on how to fix this.
