Could a get a recommendation on what people use to mount their gateway to a wall?

Hello!

I have to get this gateway off the little wooden table I have because it looks horrible but to get better signal being up higher on a wall.

I have the vendor of the gateway is Technicolor and the model is XB7, version 2.0. I measured the device and it's roughly 4.25" square. Was trying to find a device specific mount on Amazon and really didn't find anything. Would 100% prefer screwless, adhesive is great as the device doesn't weigh much.

Any help or insights would be greatly appreciated!

Best Regards,

Dave
