As far as I know removing all the internal wires except numbers 2 and 5, does exactly the same as the BT accelerator.
Other ways to speed up the internet connection are:
1. These two registry key changes will make web pages display slightly quicker as the number of simultaneous downloads is increased. Backup the registry in Windows 98 or create a system restore point in XP, Vista and Windows 7.
In a Run window (Windows key+R), type regedit, press Enter and navigate to registry key
Look for two keys in the right pane, MaxConnectionsPerServer and MaxConnectionsPer1_0Server. If they exist, then right-click on each in turn and Modify the value to decimal 10 (hex a).
If the strings don't exist in the right pane, they will need to be added manually. To add the two keys, right-click in the white space in the right pane, select New > DWORD Value, type the first name as the string name, press Enter and then repeat the procedure for the second one. Now modify the values to decimal 10 (hex a).
As the registry key is a CURRENT_USER one, the change needs to be done for each user of the computer.
2. Turn off 'RSS Feeds' by going to Internet Options > Content Tab > Feeds and Web Slices > Settings and uncheck Automatically check feeds for updates.
3. If Internet Explorer is running slowly, you may be running too many add-ons. In Internet Explorer, go to Tools > Manage add-ons’ then disable any unnecessary add-ons.
4. Reregister a dll, i.e. in a Run window (Windows key+R), type regsvr32 actxprxy.dll (note the space) and press Enter.
