Roadrunner doesn't download when traveling - Time Warner Internet

This question is about "Roadrunner doesn't download when traveling", with Time Warner Cable internet and apps. I cant download or sign into my roadrunner account when Im travelling. Not on my phone or my ipad. I phone support and they said it was a one time glitch - now happened again. Must be something to do with Specturm takeover, but havent a clue what to do? I put in the settings the person at support gave me, but its not working internationally.
