Hi... My home network has a shaw wireless router. The problem I am having is that incoming messages to apps (such as whatsapp) on mobile and tablet devices (android phone, iPhone, iPad) are often delayed. This occurs when the device is locked. Sometimes I don't get messages until I open the phone and launch the app. This does not occur when I am outside of home whether using wifi or 3g or 4g. have checked the wifi settings on the android phone and it is already set to use wifi when locked. I have checked my router settings but it is using just defaults and no restrictions. Is there anything on shaw side that delays these types of messages?
Any help will be much appreciated as this is very frustrating.
Thanks in advance.
