This has been going on for more than a month now, and I am running out of options. I have spent literally hours with my network provider hotline (Telfort, in Holland) having spoken with at least 4 different people who concluded there's nothing wrong on their side. Ever since I've done the following:
-Upgraded the router firmware (the Telfort people did it for me)
-Updated the drivers for my usb adapter.
-Tried surfing around different channels/freqs for interference to no avail
-Bought a range extender
-Tried enabling/changing/disabling my protection, nada. (At the moment I have a WPA-PSK and Mac filtering on)
-Tried connecting a (really long) ethernet cable directly between router/pc, but I get no connection whatsoever (local only, no internet)
By the way, my desktop pc is upstairs, and the router downstairs. I am aware it might be far, but my gf also has problems with her laptop therefore it has to be something else.
I will post my data below, with some links to some screenshots from the router webpage in case there is some dodgy option (de)/activated. Please keep in mind that I am not a hotshot and know literally nawt about internet/wireless etc.

I can also post a Hijack This log, if it helps.
PS. I have read several possible solutions online in different forums, but I suppose every case is probably different, that's why I decided to post my data.
Thanks in advance, any help would be vastly appreciated
