The missus and I have put an offer on a house, which has been accepted, and should we manage to sell our current place in time, we'll be moving. I've spent some time over the last few days thinking about how we'll use the rooms in the new house should it all go through...

There is a nice, quiet room that will make a great study. The desk, bookcase and lockable filing cabinet in my current study will fit nicely, and there's a phone socket for an internet connection. The problem is that it's right in one back corner of the house, as far away from the main living areas as it's possible to be, so probably not the best place to put the wireless router.

For the last couple of months I have been using the Spark-supplied Huawei HG630b VDSL wifi router/modem which has been pretty good so far. I plan to plug this into another socket closer to the living rooms and bedrooms for most of the devices in the house to use. I also still have the old Thomson/Technicolor TG789vn that the Huawei replaced, which was having a lot of wifi dropouts but seemed to work OK when the desktop PC was ethernet-cabled into the back of it. So, two questions:

1. Would there be any problem, technically or from a Spark account point of view, with having both units plugged into different phone sockets at the same time - the Huawei for wifi and the Thomson for "cabled" access for one desktop only (I assume it would be best to "disable" the wireless function of the Thomson)?
2. The house doesn't currently have a master splitter installed. I'd get this done, but how would this work - or would it work at all - if I was intending using two sockets at the same time?

Thanks...
