Wi-Fi security with a wide variety of devices
I have been running my wi-fi network on a WEP key for some time. I know it's considered to be very poor security but, so far, I haven't noticed any problems. Today I bought a new inexpensive Android tablet and it appears to be having some difficulty connecting via WEP so I'm thinking of upgrading to WPA2. I'm also thinking that I might as well do the job properly and this is the reason for this post. How much effort is justified for a secure WPA2 setup? My first question was "What's the difference between a passphrase and a key?" After some research I believe I have the answer. The sequence of characters used as a "key" is actually a passphrase. The real key is generated by the device and the user never sees it. Other comments I discovered say that the passphrase should be a random sequence and preferably much longer than the 8 to 10 characters commonly associated with broadband routers as supplied by ISPs such as BT and TalkTalk.
So here is the topic for discussion. If the pre-shared key (correction - passphrase) is a long sequence of random characters, how do I go about distributing it to all my wi-fi devices. Computers are easy... just store it on a usb flash drive or CD or floppy disc as required, but what about smartphones and tablets and printers and smart TVs? Does anybody like the idea of typing this
on an onscreen keyboard using a remote control? It gets even more interesting if the characters are hidden as they are typed.
