The modem is downstairs in the living room but my pc is in the loft, but I have the plug socket adapters that make it able to run a Internet connection through them so there's a plug downstairs thag goes straight into the modem and a plug upstairs that goes straight into back of the pc. It's gone up to 85mb now but that's still no where near what I should be getting, Isit because the cables are 5E and need replacing with the newer ones?
The powerline adapters will be the cause of the slow speed over the wired connection.
You need to confirm the speed to your HUB, as mentioned earlier, to determine if you have a stable line:

If you get full speed on the left then it's a limitation of your devices.
Oh and M350 is 362Mbps, not 400.
Wireless speeds is not guaranteed to be the full speed of your subscription, and even then it's only guarenteed to be 20Mbps, and you have to be on a faster subscription to benefit from free boosters/range extenders/pods.
