GMail question

Vicki W

I have a question concerning my GMail when traveling.
When I am at home, I have no problem receiving my Comcast or GMail. However, When I travel, even though the settings are exactly the same, I cannot receive my GMail on any wifi connection. Comcast works fine.
Does anyone know why this would be and how I can correct it? It doesn't matter if I am in a home away from home or a hotel.
