Full Node? Nope, poor network configuration... Yep, the results you posted definitely indicate a clogged network. To get results like yours on a consistent basis is very rare. It's NEVER a good thing to have faster uploads than downloads. It's almost unheard of for a DOCSIS network to have burstable uploads.
By the way, the program to view modem caps is DocsDiag. Go to »homepage.ntlworld.com/robin.d.h.···ocsdiag/ to download it.
I find it very difficult to believe your modem has a 128k cap on it. It's not unusual for ISPs to occasionally send config files with incorrect caps. You stated that your ISP is using the new SB4200! WOW! Those modems just barely came out! But since that's the case, there is the good possibility that your ISP doesn't have a config file for those particular modems. Your modem may have a "generic" config file, which for the time being will prevent unregulated speeds. A completely uncapped modem would pull in speeds as fast as the node gives it! I've personally seen what an uncapped modem can do, anywhere from 20-30Mbps down and 6-10Mbps up!!!
In regards to changing nodes--not possible. Think of your cable line & node as your telephone line & telco central office. Your telephone line is hard wired to one CO. You can't have your line physically switched to another CO. Same with your cable node. Your node is located somewhere nearby in the neighborhood. Your internet connection travels to & from that node only. In order to be switched to another node, your ISP would have to run an individual cable line from your house all the way across town to another node. Ain't gonna happen! 
It's also pretty obvious that you're not necessarily experiencing node congestion, rather network wide congestion. The only solution to this problem would be for the ISP to enforce those 128k caps, or obtain a faster backbone connection.
I remember when cable internet first came to my city 1999. My cable company used six T-1s, for a total speed throughput of 9Mbps!. Sure, speeds were great at first when there were only a few dozen users citywide. But as the subscriber base quickly began to grow, speeds began to suffer. Get this, my ISP was still using those six T-1 when there were almost 2,000 subscribers!!! It was only after speeds dropped below dial-up that we were upgraded to a fat-ass OC48 (155Mbps) in early 2001. Since then, service has been awesome! We're capped at 1500/128 and nearly everyone gets those speeds no matter the time of day. Ping times are consistently 25-40ms, and packet loss rarely exceeds 0%.
Before I forget, it should be mentioned that the only time you were close to the downstream cap was late morning & early afternoon. After that, more and more people are jumping online, browsing, downloading, trading, you get the idea! Remember, getting uploads that are 3-5 times faster than the downstream will wreak havoc on overall service quality. The DOCSIS protocal only functions properly when the download to upload ratio is at most 2:1.
Call your ISP, and see what is being done to insure that the caps are more strictly enforced. If you talk to somebody who seems clueless or doesn't understand what you're talking about, ask to speak with a supervisor. SOMEBODY there has to have a good idea of how the network is operated. Hang in there, these types of problems usually get resolved sooner or later. | | |

Boerne, TX | Thanks for all the help. That DocsDiag was the one that I was using. And it has always been a 384/128 cap, although it seems that it is not enforced. Which still doesnt make sense to me. I check through the DocsDiag on a constant basis and its always 384/128. But I am still receiving those speeds.
Now on the other hand I did uncap my modem, and the config file they are using is generic, as it did have a commonly known password for the m5 file.
I will call on monday and ask them to inforce the caps. That sounds odd huh? A user that actually wants to be capped  | |
