It would be advisable to keep the router plugged in to it's own outlet, not "shared" with anything else. If you haven't enough sockets, then try using an extension socket, the type with 4, 6, or more outlets, and plug your different items into it's own socket. This will ensure that if you unplug any item, eg. your printer or sound system, then you won't disturb anything else. The maximum load from most computer related hardware will be well within the 13 amp limit of most extension leads. So, to summarise, plug your router into No, 1, the Home plug into No. 2 and so on. Good luck.
