Hub 2 mains cable in white

[#1]

Hi, first time poster

We have moved to a new house and are unlikely to get fibre anytime soon so I am trying to make the best of my Hub 2 router.  I need to move it to a more prominent place in the house but this means trailing wires, particularly the black 12v cable across a white wall.  I have looked into a male/female extension in white but I understand the hub 2 plug has an unusual internal size (3.1 rather than 2.1)

Has anyone done this or have any other suggestions/solutions?  I don't want to use cable trunking as that will look almost worse!  Thanks

Just realised this is my 2nd post!  Moved house, different problems now🤣

Can't really help with your problem but have you checked to see if Full Fibre is coming.

I'm assuming there's no power socket near where you want the router. You could simply use an power extension cable along with a high quality phone cable.
