Weird Internet Connection Problem?

[Mightyswing995]

Hi,

For the past couple months, my internet has been fine in regards to connecting to the web, social networking, wifi, etc. But recently, I have experienced a very weird situation where my internet would stop working every 25 minutes (exactly 25 minutes) and the only thing that I have been able to do to fix this problem temporarily is by unplugging both my modem and router and then plugging them back in. My internet would then work properly for the next 25 minutes and then the process would repeat. As soon as night came around, starting at 7:30pm (exactly 7:30pm), my internet would be working fine like nothing was wrong, up until 10:00am (exactly 10:00am). I have figured out these times as I have observed this pattern for the past two weeks and every day the outcome has stayed consistent.

Modem: Motorola SB5101 Surfboard Cable Modem

Router: Tenda W311R Wireless-N Broadband Router

During the time where my internet has been down, all 4 green lights would still be up on my router so I am not sure whats wrong.

Thanks in advance for any feedback.
