downspeed is good (45-46k)... its that upspeed thats killing me(24k) ...

ive tried; checking the phone jacks/demarc -- switching 56k off (get 28.8 down 24.0 up... still stuck at 24.0)... and an init string trick of S202=32 (disable A/D detection) that supposedly helps... it worked (i got a whopping 26.4) but the connection seriously messed up after a while... so i quit using it...

any tips?

this might be a case of TMI but here goes;

modem is a hayes accura v.92 RS232 external...

init string used;
(ATZ is issued first.. to reset the modem then;)

(btw, yes.. the modem really stayed on the web for a solid 8hrs)

Yup- probably as good as it gets with the particular modem you are currently using;
It's possible - not guaranteed - you might get a slightly higher rate with a different (say USR Courier or Sportster) modem -
The absolute highest upstream rate possible would be 33.6k; - 24k = 71% of the max.

Aloha! Richard.
