3bb web problem

[orc]

might better start a new topic on this: I do have a 3bb dsl since 3 days. the download/upload speed is as advertised. But if I want to connect with the ethernet cable(macbook with thunderbolt adapter), many pages can't load properly. Like facebook will only show the header. download/upload speed is still fine. just some web access gets problem. If I connect with wifi, it's loading...but much slower as my office seems to influence the wifi from the living room, I loose like 70% of the speed compared staying in the living room, so this is no option. I'm pretty sure there is some setting that is wrong, either in the router or the computer or in 3bb infrastructure. none of the technicians at 3bb seems to have the slightest understanding of what's going on. does anybody have an idea?

when you use the thunderbolt adapter, do you switch the wifi off on your macbook?
