Slow connection after Windows 7 Upgrade

[Jordan97]

I just did a clean install from Vista to 7, and now I am having serious connectivity issues.

Straight after boot, everything will be fine, but after closing Chrome, I cannot open another webpage without having to restart the computer.

I have reinstalled Chrome and nothing has changed, but I am not getting any issues with IE8.

Speedtest.net gives me a download speed of 3.58mbps (using IE), but on my desktop I get 6.31mbps. I am with BT and supposed to be getting up to 20mbps.

Does anyone have any ideas?

Broadcom 802.11g Network Adaptor drivers are installed.

I have.

I don't need a new wireless adaptor, as it works fine in Internet Explorer, just not in Chrome.

Anyone got any other ideas?

TCP Optimizer will help you.

It didn't

I tried running it in safe mode, IE loaded but I got an 'Internet Explorer could not connect to the web page' error and Chrome crashed as soon it opened and I got this:

I also have tried running it in compatibility mode but no results.

It does not work when I connect via cable either, so I can definately rule out my wireless adaptor.
