wireless network connection lost on samba connect

Binary package hint: smbclient

Symptoms:
When you connect to a samba server over a wireless network the following happens:
1. The connection to the ap is disconnected.
2. You are not able to connect to the access point anymore.
3. Other access points work just like if nothing happened.
4. This is driver-independent

Steps to reproduce:
1. Connect to a samba share.
2. If i cannot successfully connect to a samba share then the bug does not occur.

Other Notes:
I am connecting with the connect to server option in gnome.
The server is running samba server on slugosbe 4.8 and is using versions:
samba - 3.0.23c-r1 from openslug/slugosbe feed.

The client is just running the default settings on ubuntu hardy 32-bit and is using versions:
libsmbclient: 3.0.28a-1ubuntu4
nautilus-share: 0.7.2-0ubuntu5
samba-common: 3.0.28a-1ubuntu4
smbclient: 3.0.28-1ubuntu4
ndiswrapper{
utils version: '1.9', utils version needed by module: '1.9'
module details:
filename: /lib/modules/2.6.24-16-generic/ubuntu/misc/ndiswrapper/ndiswrapper.ko
version: 1.52
vermagic: 2.6.24-16-generic SMP mod_unload
}
and of course a wireless-n network driver WUSB300N from linksys.
Note: i have this problem on many hardware configurations - all the systems with wi-fi
The ubuntu system does not have any extra repository's enabled except the defaults.

Expected:
I expected that when you connect to a samba share that wi-fi is unaffected.
