Hi Dirk,
What is your error log say on wideclient?
And those networkcards are the tricky ones i had them too and i noticed that i needed a better driver for them just dont know anymore where i found it but try to search under google maybe it helps...
I dont think your grafic card will be a problem i even run them on a basic build in card of compaq machine and there is no problem.
What you also can do is ask help of peter downson at his forum maybe he can see something
I would take the timeouts you have in your wideclient.ini to =0 maybe it also will help..
succes
