Hi,
I just bought a brand new laptop, and I have been using it with a mobile broadband connection. Today whilst browsing the internet my connection stopped working, I disconnected and when I tried to reconnect I encountered an RAS error code. Using the trouble shooting instructions, I deleted the mobile device, then plugged it back in and it re-added. After this, I successfully connected to the internet, but when I tried to open my homepage (google) as soon as the page had begun to load, the window closed itself and another opened asking me to download a html file from google.com.au I did so, and opened the file which was just a link to Google, and the whole cycle began to repeat. Please help?

Try to update any new version.. Then switch off your modem then restart again ,after that you just clear cookies ,stop multiple downloads from sites then u check your internet speed from here by use this link http://www.ip-details.com/internet-speed-test/ , if there is a problem again means just contact your service provider...

It almost seems as though you don't have a file association set up for the .html file extension. I've never seen that before. What operating system are you using?
