Please help!
I am a bit of a numpty when it comes to doing complicated things on my computer! However I will try and explain what I am trying to do and see how it goes.
I have installed a wireless network and my wife and I use it. I don’t remember being asked about security or anything when installing, and am wondering if others can gain access to our network! How do I stop others getting in so to speak, as my wife does network bank stuff and is really worried!
