Ok so this setup has been working fine up until now.
I've got a modem, connected to a router which is gives my household wireless but also connects my computer through a cable. As I said, up until now this has been working flawlessly but recently I've noticed a slight lag in my surfing. Tried it on a Swedish broadband-site and it says I've got 512 ms. Also tried it on my mum's computer which is wirelessly connected and it gives her 10ms.
Any ideas what might cause this?
