Help Wifi interferes with bluetooth

[PolishPauL]

When im on the phone using a bluetooth headset and playing with the phone with wifi on, we both cant hear much and it cuts in and out. As soon as i turn off wifi, its back to normal. Anyone else have this problem?

No one has this problem? I noticed it only does this at home. I've tried two different routers. If i turn off bluetooth and turn it back on again it'll work for a few minutes.
