I have tried disabling the router's FW, while LM was off and still could not get connected.

Yes, the problem happened oernight literally. It work flawlessly before, whether it is 4.10.9 or later. I have even tried formatting the computer but still could not get it connected.

The method of shutting off the router firewall does not seem to work. There is still a wall blocking the blue globe.

I have also called Starhub (my ISP) and they have said that they have not blocked any P2P software to date. I take it that they are telling the truth. So it seems that using a proxy should not be needed?

What should I do next?
