Recommended Posts

Did a test at http://nitro.ucsc.edu/  and i have alot of re-transmitted packets and a bunch of duplicate acks :?

uninstall that tweak from speedguide ( you can save it on your pc if you want to reinstall it )

reboot your pc

download this attached file and unzip it to C:ProgramCablenut

now open cablenut, in top left corner click file, click load custom settings file, browse to C:ProgramCablenut

dubble click on 98 & ME Cable_DSL 3000+.ccs

click save to registry and reboot your pc again

that file has a RWIN of 256960

Well Well Well,lol .... seems like there is no more re-transmirs :D . just wish i could hit my 5.1meg download rate, but I guess there is nothing that can be done cause of Win98se
