Problems with ICA client performance on 1 machine type

Hey,

we have a strange problem with 1 type of laptop connecting to Citrix. Ever since our client started using these laptops (Acer Aspire 6935) they complain that the performance is terrible; login takes 30 seconds and there is a 2-5 second delay with every action. The strangest thing is that the problem doesn't exist on any other type of hardware (similar OS/software).

Our environment:
Citrix 4.5
Access Gateway
Everything is running on one server but only serving 5 users max.

Acer Aspire 6935
Vista Business
Latest ICA client (11)

Troubleshooting steps:
Tried to reproduce the problem on a divert type of hardware with Vista Business installed (tried over 5 types) -> Couldn't find any issues thus problem cannot be on the server end.
Tried several versions of the ica client (both 9 and 10) => no change
Reinstalled the laptop with a clean vista installation (instead of the default acer install)  => no change
Started vista without any service/software and or vga mode => no change

Please some advise, this issue is really giving me a headache...

Thanks in advance!

Is it possible you have a bad NIC driver or something like that? Is it the same over wireless as it is over a wired connection? Sounds like a networking issue either way.  Check for frame or window scaling such as

Thanks for the answer, downgrading the NIC driver solved our problems.
