I did try out the first half of your request about Internet Explorer etc. Unfortunately it did not resolve anything.

I'm quoting myself because the second half I have already attempted via E-Mail support, it's the exact same information about port forwarding and didn't help either, to my disappointment.

My PC is directly connected to my modem. Always wired.

Honestly, I have phoned my ISP many times and asked them about various things. It feels like talking to a wall sometimes.

What I really want to understand is how can my connection change so dramatically after one patch? Are you able to genuinely answer this? I had no issues before patch 4.06a none at all. It baffles me!
