Virgin pods - can they be reused?

Recently got set up with virgin, unfortunately the cable access point in our house is tucked away right in the very corner on the ground floor so the router is about as far away from optimally placed as you can get. This means the signal is really strong for about a quarter of the house, decent but could be better for a little under half the house and really bad for the remainder, which just so happens to be where most of the bedrooms are with the rest bar one being in the mid zone. The previous tenants left some boxes with Virgin Pods, one of them unopened, is it possible to reuse them or is it worth just buying a 3rd party extender?

Another option we have might be to rout the signal through the house's internal TV cable network, at which point there is a much more optimally placed outlet for that I could use, but I am yet to find an access port near the cable connection to rout the signal into.
