should be redundant buy now, if you have connected the speedtouch 510 as per instructions from the following.(Follow for THE right win/os )
Take it that you are not using any USB devices on your systems to setup the connection to the 510 modem?
You may? have to reset the speedtouch to MF settings and start afresh.
(But do recap the following first)
DO ALSO print of info and follow,the 510v4 instructions by AOL and the supplied CD. Really is one of the best/simple for a wired connection setup.
Hope this may help.
