Bluetooth Conflicts with WIFI

I'm having a trouble streaming High Quality Audio from my bluetooth and streaming with the WIFI card at the same time.
I tryed to listen online radio with my bluetooth stereo headphones. Once I listen something on the bluetooth the WIFI card's transmition speed falls with 90%. It still says it is connected to my wireless router but it becomes TERRIBLE SLOW. At the same time The bluetooth works great.
That happens only with the Stereo Audio Streaming.
When I connect the headphones as a headset with lower mono quality, I have NO problems at all with the WIFI.

Equpment:
DELL Inspiron 9400:
Intel Core 2 Duo processor T7200
2GB, DDR2, 667MHz 2 Dimm
256MB NVIDIA GeForce Go 7900 GS
120GB 5400RPM SATA Hard Drive
Intel Next-Gen Wireless-N
Dell Wireless 355 Bluetooth Module (2.0+EDR)

Linksys Router - Wireless G with speed boost
Motorola HT820 Bluetooth Stereo Headphones

Please Help!

It is possible for the Wi-Fi frequency to interfere with Bluetooth as they both can operate at the 2.45GHz frequncy range. This is especially common for US and UK users as many routers by default operate on channel 11, which runs between 2.451GHz and 2.473GHz.
 
Since you can't specifically alter the Bluetooth range settings, you will need to alter the channel used by your Wi-Fi router. A channel of 6 or lower would be ideal to prevent Wi-Fi frequency going near 2.45GHz. You will need to consult your router manual to change this.
 
Unfortunately, if you are connecting to a different router, such as a public access point, where you will not be able to configure the channel, there is nothing you can do to stop any interference between Wi-Fi and Bluetooth.

GREAT!!!!!!!! It works perfect now. My router was on 6-th channel (2.437 GHz). It was obviously from it. I switched the WIFI to Channel 1 and now it is great. I read some forums afterwards... those two standards ware fighting for Freq. from a long time :(. Thank you for your fast and accurate response... A++++++++
