If you could post the model Nos. of you hub and modem, someone here will be able to advise you on a minimal hassle/possibly cost-free alternative - i.e. even if only one of your two devices has wireless capability, just set that up at your master socket. If neither has wireless capability, then it still might
be worth buying a cheapish D-Link router (~£15) with wireless WPA2 support, and then a cheap USB dongle. If you're planning on connecting modern Smart TVs to it, then they don't even require a dongle, they've got wireless built in.
I realise that doesn't answer your actual question, but if you can avoid hacking your house about and also eliminate at least one piece of old(er) hardware from the scenario, it might be a preferable option; most DSL routers released in the last 5 years or so are a "modem", "hub", and also have secure wireless capabilities. So if you could kill about 3 birds with one cheap wireless stone, then you could possibly look into it. Again though, you'd have to ask others here which brand/model to buy. For the record, I'm using a D-Link DSL2640R, which was the standard free Talk Talk ADSL router ~3 years ago, and it wirelessly gives me net access on two Samsung Smart TVs, wired (Cat 6, which is just beefed up Cat 5e) on two PCs, and Wi-Fi for my phone when I'm within range.
Sorry if you've already considered this sort of setup, but it would seem to sort out a lot of location bother for you. And socket bother!
