Vincent, we have not seen this issue before; 15.1.1 appears to be an older version. Would you please confirm it and the wireless adapter model?
it's on a NEC Versa P570 (NEC Computers - Technical Support)
Because the computer just crashed yesterday :/ I can't do any test now
Here's the MAC Address of the adapter : 00-1F-3B-93-53-61 to find the exact model.
We do not take the model from a MAC address but if you have any of the Intel® wireless adapters from the link you provided, we must say those are legacy products and are not supported in Windows* 8.1. If you have either one of them please take a look to the articles below. Otherwise, provide the exact model of the wireless adapter.
