Another alternative is to setup a VPN server on a linux-based router. I have OpenVPN running on a Netgear router w/TomatoUSB. It's always on anyway - and once it's up and running you can pretty much forget about it. I have this setup at a remote location and I've run simultaneous streams to my iPhone and iPad with no issues on Wi-Fi.

Has anyone been able to get the Optimum video exported to an AppleTV? I get mirroring to work with DisplayOut and UnrestrictPremium but it's a very pixelated picture. Both apps have their pros and cons depending on which Video App I'm running. For the Optimum App, DisplayOut is the winner, as you can resize the image to fit the TV well.
UnrestrictPremium lets you export the video stream on some apps without mirroring (HBOGO is a good example of it working well), but when I try this with the Optimum App, it just throws an error. Has anyone had any luck with this?
