Thanks for confirming that Jamie13
I've checked our systems at this side and cannot see any issues with your power level, everything looks in spec. There are also no area concerns that might be causing the connectivity issues you're experiencing.
Are you experiencing any issues on your wired devices at all, or it is just over the WiFi? I can see that you have another Pod on the way, please let us know how you get on with this and if it improves your connectivity.
Please also check that any devices that are close to the hub that can be connected directly through ethernet, such as TV's, set top boxes, consoles and desktop etc, are connected and those devices that cannot be wired in but can interfere with WiFi signals, such as any devices with Bluetooth and radios frequencies, are away from the router.
If you are still having issues, I recommend following Adduxi advice, and setting up a BQM and sharing this with us on here.
