I am new to this list.  I have read many of the post on improving speeds. I recently upgraded from Chater 1.5 to 3 meg but am not getting the full 3 meg speed.  I used Cablenut to try some tweaks and the best I have achieved for downloads is shown below.
Download Stats ..:::
Connection is:: 2603 Kbps about 2.6 Mbps (tested with 1496 KB)
Download Speed is:: 318 kB/s
Tested From:: http://www.testmy.net/
Bottom Line:: 46 times faster than 56K you can download 1MB in 3.22 second(s)
Validation Link:: http://testmy.net/cgi-bin/get.cgi?Test_ID=2SUDGHE5A

I am getting better speed after the Cablenut tweaks;   You can call me cheap, but since I am paying more for the 3 meg service I would like to hit 3 meg at least once.  I connect through a linksys 802.11b and am running XP Pro with SP2.  Should I just keep playing with Cablenut?  I have emailed Charter Tech Support and they said they would re-task my modem.  I powercycled the cable modem a few times and the speed did improve.  I have deleted all temp files and cleared all caches.  No TSR's that I know of.  Any suggestions or additional tests to run?  Thanks.

Thanks for the quck reply.  Test results below.

I could not locate the .vanburens_cablenut_settings_2versions.zip file you mentioned but downloaded and installed the cablenut update for 4.08 which contained a 3000 - 384 file.  My upload is 256 so I used the 300 - 256.css file.

I powercycled the modem and router.  Purged all internet temp files.  Much slower.

also test this http://chi.speakeasy.net/

and this  http://www.testmy.net/d_load.php?ta=1&top=mirror1&pop=1&ni=1       ( use the 3MB test )
