I have a Galaxy S3. When I'm on my home wi-fi network, when I send a text message, probably around 75% of the time the message doesn't send (and doesn't tell me that it didn't send - it just shows it as sending). If I turn on Airplane mode and then turn it back off, then the message sends. This only happens when I'm connected to my router. It seems to work find when I'm connected to any other wi-fi or when I'm on 4G or 3G.
Is there a setting I need to check on my router or on my phone or something? This has been happening ever since I got my S3. It's very, very frustrating.
Any help would be greatly appreciated.
