I had an engineer about my router to sort out my issue and he noticed that I gamed a lot during the past few days. (I rarely do but got a cool game so I did a bit lately). I just wonder how? Well I did download a game last night and last month. I am wondering, did he see just my download history (which is fine) or my internet history? I hope he didn’t as it’s just embarrassing :( I went on dating sites before I found a girlfriend and I’d rather him not see that also on top of that I brought my GF a sort of erotic lingerie. I’m so embarrassed. Is it possible for engineer to see what I search?
How much they can see depends on what the router retains so the model might allow you get get more accurate responses. Generally, routers that have logging turned on will just retain IP addresses along with some metadata about the packets like time, direction, etc. More robust routers will also retain DNS requests, URLs, etc but very few of them have the capacity to retain them for very long because those logs just keep growing.
