Drive disconnects wireless internet

As soon as I plug in My Passport Ultra the wireless internet disconnects. It can see the connection but wont connect. I am wondering if it is my adapter? I am using a HP Pavilion 500-401a desktop computer that is running a Broadcom BCM43142 802.11 bgn Wi-Fi Adapter. Could there be a conflict between the adapted and the drive?

This problem is resulting in the backups not being done when required because I can’t keep the drive continually attached.

Any suggestions?

Certain systems (particularly laptops and tablets) have problems with interference when a USB3 cable is attached.

With varying degrees of success expected, you can try re-locating the drive and cables, or trying a different USB3 cable.
