Hi and thanks for the replies.
I am using my laptop upstairs - just got an error saying that "this network is hidden" and goes onto say it is not within range!? Has been in the same position for 6 months however I have just pulled it back from being right against the wall - that is the ONLY "change" in the past few weeks - unsure if it is relevant or not.
Also, could it be clicking out and trying to connect to other networks in the area? If so how do I delete these buggers?
Thanks again,
HR
