I am using an old sierra wireless data card. Is there a device I could upgrade to that would make my home, such as tv or blue ray player internet capable? Tv has usb ports, a nd blue ray player says wi fi ready?
I would suggest you to get our WIFI Hotspot devices(Sierra Wireless Overdrive Pro 3G/4G Mobile Hotspot/MiFi 3G-4G Mobile Hotspot by Novatel Wireless/Sierra Wireless 4G LTE Tri-Fi Hotspot) to connect your Wi-Fi capable devices( TV and blue ray player ).
Hope this helps
