OpenWRT (and dd-wrt, and I'm sure most other wrt variations) let you set up another "virtual" HotSpot. If your AV equipment can do wireless, that's an option.
Also, I just bought my mom a TP-Link device capable of running openWRT for $25 (don't recall the model). If you care about privacy, it's relatively cheap in enabling hardware - it's your time that is going to be expensive.
