Hi All, advice please. I have been given 2 adaptors,WPA281, which will give me WiFi coverage in a spare room. I have plugged them both in, paired them up and now the WiFi works perfectly well in the spare room.The problem is that it keeps being flagged up as an "open network" and is insecure. I have not got an operating CD disc for it, I cannot find an operating  download on the internet and would like to know how do I password protect the device so the network becomes secure.Thanks in advance Phil
