wep might as well be open. its like putting a sign on your door saying lock broken please dont enter.
wireless router isnt complicated to setup.
if you need some help post some screenshots of what you dont understand (I'd try googling it first as thats instant answer)
basically with a wireless router you
1) pick the frequency and channel, encryption method, password for the router, router name(for wireless) router wireless password
you want to use WPA2 encryption, 2.4 ghz channel 1,6,or 11
whichever channel is least busy(can find out with free smartphone app - inssider)
Pick a router name that doesnt identify you but easy recognizable. ie. not your last name, something like Duckshack, FBISurveillanceVAN, whatever. Mine happens to be called Toomanytires
If you have any questions about "channel bandwidth" or other options usually you can just leave it to whatever the default setting is.
also maybe explain your basic house layout and constuction and where your wireless is located and how its oriented.
