I have to tell you that I have had the exact same issues for a little more than a month. I live in Bournemouth and my internet is now very slow, disconnects a lot. It's a pain to surf at all. I have Huaweii E220 + a Touch Diamond with unlimited data. The Touch Diamond has also been experiencing some serious connectivity issues in the past month. I've stopped surfing with the Diamond because of this.
