So, We have a wifi router in our bedroom and in there we get speeds of 36 Mbps. In the lounge, we have the extender and that extender means we get a full signal in the other side of the house, but even when the signal is showing full, we're now only getting speeds of 5 Mbps. This is consistent regardless of device.
What's going wrong?

Some time has passed since the initial question was asked, but I'm not thrilled with the answers here.
You say you are getting a 36mbps speed in the bedroom, where the router is, and only getting a 5mbps speed in the lounge, where the repeater is.
Assuming that there is no interference from other devices, and there is a relatively clear path between the router and the repeater:
What you could do to improve this situation is put the repeater halfway between the lounge and the bedroom. When you connect your device from the lounge, you should get a better transfer speed.
Why? Because the speed of the transfer drops in an exponential manner the further the repeater and router get away from each other. By keeping the repeater a shorter hop from the router, and then your device a shorter hop from the repeater, you keep the signal stronger along the whole path, rather than having a weaker/exponentially slower signal between the router the device.
Hope this helps even though some time has passed.
