We understand you're having connectivity issues when using wireless while your Bluetooth® module is enabled.
In this case, I'm inclined to agree that this is a likely antenna issue. Bluetooth® uses the 2.4 GHz band, which is why it's common to see interference issues when you're connecting to WiFi on the same band, but it does not cause issues with the 5 GHz frequencies, since these are not used.
Your adapter uses the following antenna configuration:
Antenna 1: Wi-Fi + Bluetooth®
Antenna 2: Wi-Fi
If there are issues with antenna 2, your adapter will rely solely on antenna 1, which is shared. This will result in increased latency when your Bluetooth® radio is enabled, as your adapter will need to take turns using this antenna.
Although not a simple solution, our main recommendation in this case will be to purchase a set of replacement antennas from your computer manufacturer. Perhaps a local repair shop or one of your computer manufacturer authorized service centers will be able to help install this part. If this is not an option, an USB Bluetooth® dongle may be a simpler workaround.
You can also test our latest drivers (released earlier this week) and see if they mitigate the issue. We recommend installing the Bluetooth® driver first, followed by the wireless package.
