Lenny 19213 WPA problems

[frenchie]

I just upgraded to lenny's newest rom, but I cannot connect to my WPA-tkip network. When I click connect on my device it will try to connect for about 5 seconds then go back to available.

I've tried the WPA-TSK fix, but it isn't working.

My router is a linksys WRT54G.

Thanks for any help. I really like this new rom and I don't want to down grade.
