Don't give up - wireless is easy...........eventually
For general info (you don't need to know this, but hey...)
WEP is now old, but yes the Hummy will do this (mine is set up with WEP - long story)
WPA has a few versions.
WPA uses TKIP
WPA does both TKIP and AES
These are authentication protocols - you just need to chose the same one as your router if it doesn't select it automatically.
PSK = Pre Shared Key ie the pass code you use
If it is PERSONAL then it is using PSK - this is the one for home (ie personal) use
If it is ENTERPRISE then it is using certificates - complicated and for business (ie enterprise) use.
Best for home use nowadays is WPA2-Personal......which is WPA2 with AES and PSK.
Is your head spinning yet
