Trouble with 5GHz WiFi and Bluetooth?

Is anyone else having trouble with 5GHz WiFi and Bluetooth?

Whenever I am on my 5GHz SSID, Bluetooth turns off whenever the tablet gets a DHCP lease renewal. I verified this by looking at logcat. Here are the relevant lines:

I can manually reproduce it by:

Connect to the 2.4GHz SSID

Enable Bluetooth

Switch to the 5GHz SSID

Then Bluetooth switches off.

If I do the reverse sequence:

Connect to the 5GHz SSID

Enable Bluetooth

Switch to the 2.4GHz SSID

Bluetooth stays on.

Does anybody have any ideas?

Thanks.
