Sky, to get Openreach.
The modem is supposed to be connected using the short cable that comes with it. If you want it further away than that from the master then the free with installation "Home Wiring Solution", (Data Extension Cable), should have been ordered. Most ISPs order that just in case, as it costs nothing.
I believe the standing instructions to the engineers by Openreach are to wall mount it, though not doing is allowed if you request it. The early ones did tend to self-destruct from heat, the Type B, (see the label underneath), is usually OK. You should have a Type B as the early ones were supposed to be replaced free and not re-issued.
The router can be any valid ethernet distance away from the modem.
Sounds like another newbie engineer did it.
