I've always used BT for a wireless keyboard and mouse, but lately I've started having my laptop always connect to my phone in order to use Phone Events (feature in Salling's Clicker).

Since I've started doing that, I've noticed deteriorating performance with my WiFi. I will suddenly lose routing ability, and it will suddenly come back up. I don't think its my router, b/c it happens at home, at any client's office I visit where I use their wifi.

Turning off BT is not an option to utilize wifi as I'm always online for work purposes, and the BT phone events actually helps my workflow to the point where I've used it enough to where I can't take it out of my workflow now.

ANyone have any thoughts on what might be going on?

More than likely it's the phone's signal that's overpowering the WiFi signal than BT interfering with it. Both Bluetooth and WiFi systems use fairly low power levels compared to most cell phones, so when your phone is on, it could be producing a hefty signal level (even when not in use-they "check in" with the cell system so they can connect when needed) that is much larger than the WiFi system can handle.

Hmm, that's a possibility. I guess I'll try switching to my backup phone for a week and see if it makes a difference. I never had this problem with my Treo, but I've started using a Sony Ericsson lately (for the past month), the problem only started over this past week though, and coincide with when I started using the BT connection all the time to my cell phone.

I never noticed you are in San Antonio, I've been following your posts since I started peeking at MacNN back in 2000 and still lived in Austin. Had I realized I would have made an effort to meet the face of one of the users I have gotten a lot of advice from over the years.

Does the setting "Use interference robustness" help alleviate crosstalk? I've never really understood why you would not enable it by default.

from Apple
Base station Interference Robustness, which provides improved performance when 2.4GHz devices like cordless phones and wireless video distribution system cause significant interference with the AirPort network.

Thanks for the vote of support, mpancha. It's quite possible that using your BT connection puts the phone closer to the path between your computer and base station, which would cause the phone's signals to be "in between" your computer and base station. This is an example of two particular forms of RF interference: the frequency the phone is on can be close to a "partial harmonic" of the 2.4GHz frequency the WLAN is on (as in 1/3, 1/2, even 2/3 the WLAN frequency), and it can be powerful enough to "out shout" the WLAN signal, reducing the available, usable signal that gets to its destination.
