@Jkgv sounds like an older booster which will only work with the black hubs or to help Sky Q boxes. Assuming you have thst set up move the booster close to the hub and seecwhetger it connects properly there if it dies move it no more than half way to where you need the boost as the problem couldcsimply bbe it was out if range of the hub.
If still stuck call Sky assuming of course they supplied the booster
