Dear Mud Wizard,
Many many thanks for your response and kind step by step help. i feel i might get somewhere with your tips and help.
1 - I did setup a BQM graph, and I enabled Wan Ping Respond in the Superhub sttings, then rebooted the router.
here is the link:

2 - i pinged my powerline to the IP address you provided. the results were different each time. take a look:
3 - i can not remove the aditional wifi adapter, as some roommates can not connect to the superhub's wifi as of their weak wifi devices.
4 - using either wifi or powerline, as soon as i launch black ops 3, my internet disconnects. this has been the issue since last night. i dont know why!
5 - downstream, upstream and network log: (network log seems to show October instead of November for some reason. so if i checked the network log tomorrow, it would say 19/10/2015)
