If you don't have any key whatsoever, use WPA2-PSK - to my knowledge, it's the most secure one you can use.
Seeing as you're only getting two bars and slow speed, someone could have logged into your router and messed up the settings OR there's interference from someone else's router/cordless phones and you'll need to change the wireless channel.

Both of these
I have WPA-TKIP and a MAC Address filter on my router because of the same thing that you describe: Crappy connection. I found out that it was due to someone hopping on my network because the idiot had library sharing active in iTunes, so I saw his library when I opened up iTunes to sync my iPod. MORON.
So I put on a MAC address filter and then tried WPA2-PSK, but the Mac and Wii couldn't connect to the network with that on for some reason. So I went back to WPA and everything connects just fine, no one has been on my network yet and it's been a bit faster
