Can I connect to both a Wifi router and a Wifi Music receiver at the same time?

I want to be able to play music from my android phone out of my home sound system, wirelessly. Bluetooth doesn't have a long enough range, so I was going to use Wifi. I also want to be able to connect to the internet on my phone (Spotify etc), at the same time. I was going to buy this: Amazon link But I first want to make sure that I can still connect to the internet (through WiFi router) if I am using this. I do not want to route my phone. Thanks.
