WIFI: Association times with ndiswrapper > 7 mins

Hi, I need some help with these .
I'm experiencing a wireless association problem since I installed ndiswrapper.
Sometimes it associates to the router inmediatly but another times take up to 7 minutes (or more).
My card is a Broadcom 4310 USB (inside a Dell Insipiron 1525)
My router is really near (less than 1 meter)

With Windows Vista (preinstalled ¬_¬) connects inmediatly. I also tried the propietary Broadcom driver "wl" and it connects inmediatly too. (But the connection is really bad when the signal is not at 100%)

I tried by using the recently released ndiswrapper 1.53 but I get the same results.

I'm using netcfg2 2.0.6
My kernel is 2.6.25.10 (x86)

The Windows drivers are from the Dell website for my wireless card (x86 version).

When the connection is finally established, the navigation is OK

Here is the lspci output:

0b:00.0 Network controller: Broadcom Corporation BCM4310 USB Controller (rev 01)

"ndiswrapper -l" output:

bcmwl5 : driver installed
        device (14E4:4315) present (alternate driver: wl)

( the "wl" module is installed but no loaded)

Here is my netcfg profile:

CONNECTION="wireless"
INTERFACE=wlan0
SCAN="yes"
SECURITY="wpa"
ESSID="XXXX"
KEY="ZZZZ"
IP="static"

GATEWAY="192.168.1.1"
TIMEOUT=20

(i'm using static IP instead of DHCP)

iwconfig output (when it's connected):

Here is the iwevent output when it takes a lot of time:

.... a lot of "Association Request/Response" messages ....

13:49:47.248244   wlan0    Association Request IEs:0006656D694E455401088C9298A4B0C8E0EC210208122402010E30140100000FAC040100000FAC040100000FAC020800DD09001018020010000000DD0600409

13:49:47.248305   wlan0    New Access Point/Cell address:00:E0:4C:F6:EA:6B

(then it stops and I can ping the router and browse the web)
(( when the association messages are displayed without stopping I can't ping the router))

If I forgot some relevant information, please tell me.

UPDATE:

It seems to be related to WPA/WPA2/TKIP/AES router configuration. After reinstalling the ndiswrapper drivers (while testing another drivers) and setting the router configuration to WPA2 Mixed ( WPA+TKIP + WPA2+AES ) the issue seems to be solved (association takes less than 20/30 secs) , but it needs more testing.
