RTT and RTTd spikes that leads to WAN disconnect.

[sonic1812]

I am having an issue with my router that is causing spikes in RTT and RTTd. The issue is spontaneous as it will happen randomly.  Dpinger will show the RTT spike up to a high amount and that's usually when the internet will disconnect. What could the cause of this? I think it has something to do with my WAN interface settings, but I am not sure what else it could be. I have  used another router (OpenWRt) and didn't have this issue when I used it. Here is more information:
WAN Interface Settings:
1.    MTU= Blank
2.    Override MTU=Checked
3.   Block private Networks=Checked
4.   Block bogon networks=checked
5.   MSS=Blank
ISP INFO
