I contacted Comcast and they only suggested to disable my firewall. . . these are my test results with firewall  turned off!   I'm using Windows w/sp2.

ANY SUGGESTIONS ON WHAT I CAN DO TO GET BETTER SPEEDS?

OK, finally . . . thanks for unlocking.
I'm connected using a Motorola SURFboard SB5120 USB Cable Modem

i assume you have cablenut installed, open cablenut adjuster, click delete cablenut tweaks + save to registry and reboot your pc

download vanburens_cablenutsettings_2versions.zip here http://testmy.net/forum/index.php?topic=1013.0

unzip it to C:\Program\Cablenut

open cablenut adjuster, in top left corner click file, click load custom settings file, browse to

C:\Program\Cablenut\vanburens_cablenut_settings_version_2\VanBurens cablenut settings Version 2\WinXP_2K_CABLE_DSL\MSS1460

dubbleclick on Cable & DSL 3000 384.ccs ( assume your upload cap is 384) if its 256 then choose Cable & DSL 3000 256.ccs

now click save to registry and reboot again

try speed and post result

good luck

Anyone have any ideas?

I can't believe I didn't think of this before.  On my Comcast HSC -  Motorola SURFboard SB5120 USB Cable - it has both USB and Ethernet.  Well, I unpluged the USB and pluged in the Ethernet cable to my on-board adapter and OMG - I'm 24 times faster!

Here's the speeds with USB:

Now, I'll start messing with Cablenut to get the BEST setting.

Hope this is the start to helping anyone else . . . GO ETHERNET!! - OH, it is after you post...

sideline: how do you get WYSWYG editor going in this forum?

Oh thanks CA3LE Always wonder what that Merge feature is hehe
