Internet connection randomly goes off?

[875]

Hey guys, I need some help understanding and fixing my internet connection's strange behavior. It seems that my connection will randomly go off. I tried closing (shutting down) my router for about 10 minutes and opening it again, but it didn't always work. Well, this method used to work but for the past few days the success rate was quite low. Restarting PC also didn't work. I have been told that it may be due to my computer, but my wireless network also didn't work, although it showed that wireless network is connected on my phone. The phone seemed to have trouble locating the server when connected to this wireless network. Upon looking at my router, I found that all lights were lit as usual. None of them was blinking. I tried running a diagnostic test through the router website (192.1.1) and it did show some failure. The screenshot is attached below. Your assistance is highly appreciated. Thanks
