About the only other option is streaming data over a cell phone or MiFi. Not exactly cheap unless you have an unlimited data plan.
You can connect your cell phone to the TV but it is not high resolution (lower than 1080 on average). I have good luck using the phone as a hotspot and using my tablet for viewing.
If you have less than 2bars on your cell phone the video will stop to buffer quite a bit.
FWIW, we use our cell phones for our internet connection. About 70 to 90GB per month.
