    i have tried different sets of value as for the moment this is
    " THE BEST " connection i ever had at 15KB/s.
    and
    SMARTBRO INC. CO. keeps telling me that i have a "GOOD CONNECTION".

    i'm asking for anyone who could help or suggest for a real connection ..

    You can try bumping up the RWIN value to 64240, seems you've already done quite a bit in optimizing it.
