I believe so, and it's less than useful on network with a captive portals like hotel rooms.

At least the upcoming Chromecast with Google TV comes with a remote, so you should be able to interact with the captive portal and use it that way.

While the chromecast's inability to work with captive portals is it's own problem, they make tiny wifi routers, half as tall and twice as thick as a smartphone, and they're cheap. If you find yourself facing captive portals more than once, I'd recommend buying one so you can use your Chromecast in hotel rooms, among other use cases.

I already have one from TP-Link, but having the new Chromecast would allow me to shrink down on hardware even more.

Most smartphones are also wifi routers
