The new Apple MacBook Pro with Touch Bar is pretty cool. It’s fast, the retina display is gorgeous and I like the convenience of being able to log in with my finger thanks to Touch ID.
I’m yet to explore all the possibilities of the Touch Bar as I’m still busy installing apps I need on the new laptop as well as transferring files from the old MacBook.
I rely on a Seagate 2TB Backup Plus Slim portable hard drive to transfer files between computers. Because it’s a USB 3 drive I connect it to the new MacBook Pro through a USB 3.1 Type C to USB adapter.
For some reason when the external drive is plugged in, the new MacBook would not connect to our wifi router. It’s a pretty recent 2.4 Ghz 802.11n router that has worked fine with my old MacBook Pro Retina.
I tried almost everything including deleting the network, rebooting the laptop, rebooting the router, re-entering the passwords, etc. The new MacBook Pro with Touch Bar would not connect to the wifi router.
As last resort I unplugged the Seagate external hard drive and rebooted the MacBook. After logging in the wifi symbol turns black and the Dropbox icon starts to spin again. Hooray! The MacBook is connected to the internet.
I conclude the issue was caused by the external hard drive.
After some researching I found this message on Apple forums:
The explanation was radio frequency interference created by the hard drive can cause disruption to wifi and bluetooth devices.
A solution I found was to connect the hard drive to the MacBook but keep it as far of the laptop as possible (limited by the length of the cable). I now have access to the internet via wifi at the same time as the external hard drive is connected.
