I'm still struggling with my easynet wireless card to.

I used the original software provided by amiga kit.
Strangely my amiga 1200 freezes as soon as i try to go online. Just a short blink from a led on the wirelesscard and thats it.
Checked the wirelesscard with a laptop and it worked fine, so the problem has to be the software or de hardware of my amiga. Tried miami-dx as well, wich results in the same problems.
Anyone an idea?
Is there a chance this is caused by timing issues?
