As well as dubious wireless adapters Dell also shipped a USB GigE adapter for some XPS15 models that doesn't work for more than a few hours before the adapter crashes and needs to be power cycled by removing and reinserting it. I had a customer with one XPS15 that contained both the terrible wireless and terrible external wired network adapter.

The story gets better though, Dell shipped a demo model of a new XPS15 recently and we discovered the improved USB3.0 GigE adapter that it ships with is now stable, so got them to swap the older ones out but customers shouldn't really be testing hardware that is unable to perform its basic function reliably.
