>Description:
First of all. I've been trying with several -current version (since 3.99.3 actually).
I have a wireless network at home. I use it to nat my internet connection (6mbps).
I can download stuff up to (760kb/sec average).
When I use my AP and WI CARD in unsecure mode (no WEP) I can go to this speed.
With a 64 or 128 bits key I only get 1/3 or 1/4 of this the 760kb/sec.
I've been told WEP (de)cryption is not a costy operation so I should get the same speed.
>How-To-Repeat:
Try to download stuff on an unsecure network (no WEP) and then on a secure network (with WEP)
>Fix:
None
