has anyone encountered a slowing of upload after tweaking with cablenut?  it did wonders for download, by 100%! unfortunately gaming sucks with upload at .2 and .3. please advise, settings in cablenut maybe???

im on Comcast, advertised 6 down and 1.5 up. i did cablenut with the calculator. also the three changes including DNS, faster page loading, and increase buffer. it increased my down to 12 average, sometimes a 16! but up stays steady at .2 or .3. something to note as well, when network area is bogged down, my download suffers, but usually my up stays steady...

They don't offer a 6/1.5 up package and I think your upload is powerboost and you have the 6/384 package by them.

OK, here is what the cablenut and the calculator came up with for my system and connection. im running xp service pack2, amd athlonx57 oc'ed, 2gigs RAM, 2-80gig hardrives RAID0, 512GTX graphics card, xp trimmed to 14 processes. i am at 6 download and 1.5 upload with speedboost (so im told). below settings put me at 13 download and .2 upload. i have reverted to the cable_normal_2k ccs file, and my speeds are normal again. with below settings is there a reason my upload crashed after implemented???

I would think the reason the speeds went lower is because it was optimized for a lower speed and couldn't take advantage of the powerboost.

I actually had speed drops, both up and down, after installing cablenut. Not saying it's a bad program, just didn't work for me. 

And I have nothing but bad things to say about Comcast. Their service is terrible and their customer service is nonexistent. They scheduled a service call for last Tuesday between 2 & 5. I called Sunday morning and informed them that they should actually check with me before scheduling since I have to work until 6 and would not be home by 5. They told me they would reschedule for 5-8. The next day someone else called at 10 P.M., waking me up, to confirm my appointment for "tomorrow between 2 & 5". I explained again that I would not be home at that time and that I had already rescheduled for a later time. She made the notes and assured me that it would be taken care of. When I called at 5 the next day, I was told that the technician was there at 2:11 P.M. but no one was home to let him in. Imagine that!!

If you are having problems with your ISP tweaking it wont do anything at all because you need to get it fixed and if they wont do it right find someone who will or complain like hell till they fix it. 

I did that to my old cable ISP and got 7 months of the fastest speeds they offer free
