Xperia X Bluetooth kills Wifi

[Flythe]

Hi,

I've got some troubles using my Xperia X with both Wifi and Bluetooth activated at the same time. My home Wifi (2.4GHz) works fine usually, but as soon as I connect my smartphone to any Bluetooth device (I own both an SRS-XB2 loudspeaker and the MDR-1000X) the Wifi loses connection within few seconds. The connection can be re-established in Wifi settings but will fail again within seconds. This error occurred both on Android Marshmallow and Nougat.

You're not sharing the internet connection in bluetooth settings accidentally right?

I'm not. As far as I can see there isn't even an option for that.

Both your WiFi and Bluetooth are using 2.4ghz.
The WiFi is dropping due to the large interference from the Bluetooth connection.
A problem on many devices where user still using 2.4ghz wifi

This might be the case, but I had never any problems connecting my Z3C to bluetooth devices on the same network.

If you recently updated from MM to N try with a software repair. The issue is partially due the frequencies as discussed above but a software repair usually fix it. Apparently configuration of the network stack is not updated correctly. You may see an improvement if your WiFi router is dual band and you disable the 5Ghz band. Definitively, a solution that works for many is the software repair using Xperia Companion app.
