does essential mean cant share files or cant browse the web? does essential mean cant play online games?
No you can do all those things, its not essential to enable your network to work, nor was that what i said
apj101 do you live in a neighbourhood full of hackers? and if you did and they wanted to break in and they were good would your encrypting stop them?
Why would they have to be hackers, if you running an open network they could be anyone, kids, moms, even my grandma could connect to an open wireless network if some idiot were to run one in range.
I have run a wireless setup for more than five years and never had any problems
How would you know if someone was stealing your bandwidth/files/uploading malware. If you not using wep/wpa then i doubt your monitoring your network traffic. Who knows whos on there.
Really
but I would guess that encryption reduces speed in some way and if you feel safe then you dont need it
Yes it does reduce speed, but not significantly. You would notice it on large file transfer over 300-500MB, probably a few second extra. You will not notice when browsing the internet, as your internet connection is by far the limiting factor
and if you did and they wanted to break in and they were good would your encrypting stop them?
Well in my case they would need to bypass the wpa, then mask there MAC address, then find an available IP from the very narrow range with no DCHP, then bypass my admin password. I would say by the time someone has got past stage 2 they are good enough to go all the way. Oh and i monitor my traffic all the time, so as soon as i see them i would kick them off.
essesntial is wrong, wireless networks can exist (like many do) with it.
Essential for operation... no
essential for security... definatly
Without encryption people could be
stealing your bandwidth
Stealing your files
infecting your machine
placing keylogger, and collecting bank/online banking/credit detail
steal your email access and read sensitive emails
In fact depending on your job you will have a liability to keep your machine as secure as possible if you maintain "work" data online, i know i do for my clients
There is so much more i could say, but i feel i'm wasting synovial fluid on you
