need help with my privacy? please?

[fas-110]

Hello,
i live with people who are not my family so i want my history and mac to be private and i use their router which is NETGEAR Rangemax WNDR3700 Dual Band Wireless Router and opera browser i use private tab for my private stuff and have firewall high mode on, so is there any possible way they can look into my history and stuff from the router or any where?
and they also have another one which d-link.

if the people who are not your family, have advanced computer skill, especially Networking skill maybe they can look into your browsing history or other stuff when you connected into network,
but if they are ordinary computer user, i think you are safe enough,

do they have physical access to your machine? if they do they can find out a lot unless you use a good password.
