Connection dropping due to content I am browsing?

I moved over to SKY a while ago and in the last 3 months if I go to a "male interest" website the connection drops. Things like Nuts, FHM, anything of a male nature. I am connected wirelessly and after about 3 minutes of going to one of these sites the connection drops.

The router looks like its still connected but its as if no traffic will pass though.

I restart the laptop and I am back up and connected again?

Does anyone know if content is filtered, or on a seperate note how I can reconnect without having to restart the laptop?

Have you tried refreshing the page?
I doubt they would censor those sites and you would not get in to start with if they did. I have never heard of ISP blocking Gay or Adult porn sites.
Some ISPs allow a charity to block sites supplying Pedo stuff and they have made a couple of errors, but again I doubt that is happening here.
Possibly a DNS problem if it only these sites or a router problem if it starts happening on other sites.
