Usually slow or dropped connections occur when the modem is having difficulty communicating with the DSLAM in the exchange. This is usually due to line 'noise'. If your line has external noises they will interfere with the data and cause corruption therefore dropping the line or slowing valid data transmission. Check that all devices connected to your phone line have filters, phones, faxes, back to base alarms etc.
