Whenever I connect an external monitor to my MacBook Pro via a Thunderbolt/DVI adapter, the Mac
loses its wifi connection. Huh?
My setup: A MacBook Pro 2013 model with Retina display, a Thunderbolt/DVI adapter hooked up to an
external old Dell monitor. The Mac has a stable wifi connection - until I plug in the DVI adapter.
This problem annoyed me for quite some time, up to the point I did not even use the external monitor
anymore. Today, it happened to me again, and I decided to finally try and tackle the issue.
I found this discussion
titled "My wifi drops when I plug in an external monitor through the thunderbolt port". In this discussion,
a workaround is suggested - which is changing the wifi channel!
And indeed, this helped! Before, my router was using channel 4. I reconfigured the router
to select an appropriate channel automatically, and now it is on channel 1, as confirmed by the
Wireless Diagnostics tool
