Do you have a new laptop computer? Would you like the freedom of sending e-mail & surfing the Internet from the garden? A wireless network is what you are looking for. More importantly, a secure wireless network is what you need setting up correctly.
Need advice? Give me a call, my advice is free, & I may be able to help you over the phone - from installing a basic home thin ethernet cabled network, to solving wireless security problems & everything in between (router settings, wpa keys etc).
