When interpreting your connection speed you need to factor in the maximum speed your phone line will support. In order to achieve 8MB connection speeds, your local exchange must be capable of this, BT will be able to confirm this for you. Other factors may include your distance from the exchange, you can boost your signal by going to the website of your modem and downloading an extended reach driver. You may also have a fault partly blocking the ADSL signal on your line, your ISP will be able to test this for you (BT will only confirm if it's capable of voice calls). If none of that helps it could be your pc, if you are using alot of system recources, and you have a software modem (which if it was free from Bulldog it will be) your speed will be affected. Try typing msconfig in start and run and checking the startup tab. If you have anything prior to WinXP be careful if you uncheck any of the boxes as they may be needed for the operating system to run correctly.
If you pay for an 8MB connection through Bulldog then they are contractually obliged to provide this unless your contract states upto 8MB. You usually find that slow speeds aren't down to the ISP.
thats great help cheers iv been told by bt it can handle the speed rang bulldog and thay said i should be getting 8meg i am trying to find the extended reach driver you mention i.tech but carnt find it
