Slow Upload Speed and Ping Spikes on C6300v2

Hello,

I just purchased a C6300v2 after having an Xfinity provided modem/router and am experiencing heavy upload speed fluctuation as well as ping spikes while gaming. I work from home currently as most of us do, and the upload speed fluctuation is horrible as I work out of a shared outlook email box which needs constant and stable connection to function. My outlook box drops service a few times a minute since I switched to netgear. I found another post with a similar issue, and even more specific, they mentioned that their ping in league of legends would skyrocket at exactly 0:55-1:05 into the game which I also experience every single game since switching. Another similar post mentioned something about openWRT or DDWRT which I checked and this router supports neither. I had a comcast rep come out and rewire the home and the issues persist. If I reset the unit the issues will subside for a few hours until they return. 

Is this a common issue with this model that it has poor RAM management and requires frequent reboots? If so I am still within my amazon return window and will likely return it so timely responses would be appreciated greatly!

- It seems their issue went unsolved or they resolved it without updating the forum. Is there a way I could message this user and ask how they resolved their problem? OriginalOwls
