Hi,
I have an existing wifi connectivity to the internet (SSID "public"), and I want to add a new private wifi (SSID "private") which will use the public internet connectivity.
I have setup my TL-WA901ND as a wireless bridge using this tutorial http://www.tp-link.com/en/faq-227.html
It works just fine with one exception:
When I have connected SONOS speaker to my "private" wifi, I can also access it when I connect to the "public" wifi, which is of course not desired.
Could you please advise, how can I fix it?

Thanks
