Can't use wireless LAN =(

[Bjorne]

Hello!

My Wireless LAN has stopped working for my PC, if I try to connect to it with windows I see a progressbar until I get a time out message.

If I try to connect with my PSP it says:

Connecting to access point.
Exchanging key information.
*then it goes back*
Connecting to access point.
Exchanging key information.
*back again*
Connecting to access point.
Exchanging key information.

until I get a time out error

I've tried resetting the router, without luck. It's a Zyxel Prestige 335WT.

Thanks

I don't know what I did but the PSP suddenly said "obtaining IP address" and worked ^o)

now it says a connection error has occured =( is there something wrong with my router=/

ok hehe update:
I installed Zyxel's own tool, didn't work either, I upgraded the signal to WPA2-PSK and after that I got a connection... weird! the connection is at 11Mbps now though, before (that is before these problems) I got 56-125....
