So, I've had this issue since I bought my new router which is D-Link 615. But I noticed that every 20 minutes it drops connection for at least 5 - 10 seconds. But the thing is, if I use my normal Ethernet Connection, nothing happens. So, I am thinking that my D-Link 615 is having an issue. So, any suggestion and advises would be High Appreciated... because this is so frustrating.
