At my lake house I use PdaNet+ on my Android phone for a wireless hotspot. Old verizon plan with unlimited data. Signal strength is generally 2 bars 4G LTE. I have a Slingbox 350 at home. I have a TP-Link wireless router so that I can cast to TVs in different rooms. I use my iPad to initiate Slingplayer, and then cast to a Chromecast (v2). I am having issues with the Slingbox and Chromecast staying connected to the wireless network. I have the latest Slingplayer app on the iPad and the Chromecast is current. Any suggestions to improve connectivity?
