You can certainly use WIFI from your latop and even the DAC. The DAC however requires more attention for good results, since it is the endpoint.
If you want a WIFI solution that sounds really good, I have one with grounded LPS supply and CAT7 cables as well as an isolator. Not cheap though. You just located this next to your DAC and plug the Ethernet from the DAC into this. It is WPS enabled, meaning that it learns your network and password from your router. Once it learns this, then the network is secure. During the programming, it's not secure. Takes about 5 minutes.
WPS I believe is Wireless Pairing System.
