The "why can't we get a ###kbps upload??" has been discussed many times; particularly cable modem internet forums. Most users might run FTP servers, game servers, web servers, MP3 servers, or any other 24/7 activity dealing with the upload if it is fast. If the upstream is saturated, everyone will slow down to about the speed of the advertised upload. This is a TCP/IP flaw for just about all types on internet access, but only this will affect all the computers on the node rather than the single computer. There will be complaints about slow downs/huge pings/packet loss on your node. Say goodbye to gaming, hello to 56K.
DSL has more of an advantage over this. Because cable-modem users generally share a network loop that runs through a neighborhood, adding users means lowering performance in many instances. ADSL provides a dedicated connection from each user back to the DSLAM, meaning that users won't see a performance decrease as new users are added -- until the total number of users begins to saturate the single, high-speed connection to the Internet. At that point, an upgrade by the service provider can provide additional performance for all the users connected to the DSLAM. This doesn't exempt DSL users from running servers though.
The upload bandwidth use could be regulated with a cap, and a few dollars for extra MB over the cap. But still, there will be complaints about the limit. Some would want it removed.
There is no method to make everyone happy. You are just going to have to live with what you have...128 isn't all that bad for gaming, because pings are considerably lower than that of 56K, and casual uploading.

Information on signal levels: http://homepage.ntlworld.com/robin.d.h.walker/cmtips.html#signal
Downstream power level (Receive): -15dbmV to +15dbmV
A value of -15 or worse indicates a poor downstream signal path. A tech would aim for a value close to the optimal 0 dBmV, but a good cable modem should be capable of working within the broader range of -15 to +15 dBmV, provided the downstream Signal to Noise Ratio remains good enough.
Upstream (Transmit): +8dbmV to +58dbmV.
A value within the range +25 to +55 dBmV is within spec with 40's the most common. The lower this figure is, the better the upstream path to the UBR. If the cable modem is going offline, and the upstream signal strength is at +58dBmV, then a poor upstream path is probably the problem.
Carrier/Noise Ratio: 30dB to 36dB .
The downstream Signal to Noise Ratio must be 23.5 dB or higher, and should ideally be 30 dB or higher. The lower ratio the more noise and the poorer the performance. The Cable Modem will have to keep requesting retransmissions of packets with uncorrectable errors.

1.1 General Questions about Cable Modems·How does a Cable Modem work?
·What is DOCSIS and what does it mean?
·What are the advantages of using a cable modem to access the Internet?
|
| (back) |
Cable Modem Termination SystemThe CMTS provides, at the cable-provider's head-end, many of the same functions provided by the DSLAM in a DSL system. The CMTS takes the traffic coming in from a group of customers on a single channel and routes it to an Internet Service Provider (ISP) for connection to the Internet. At the head-end, the cable providers will have, or lease space for a third-party ISP to have, servers for accounting and logging, dynamic host configuration protocol (DHCP) for assigning and administering the IP addresses of all the cable system's users, and control servers for a protocol called Data Over Cable Service Interface Specifications (DOCSIS), the major standard used by U.S. cable systems in providing Internet access to users.
The downstream information flows to all connected users, just like an Ethernet network -- it's up to the individual network connection to decide whether a particular block of data is intended for it, or not. On the upstream side, information is sent from the user to the CMTS -- other users don't see that data at all. The narrower upstream bandwidth is divided into slices of time, measured in milliseconds, in which users can transmit one "burst" at a time to the Internet. The division by time works well for the very short commands, queries and addresses that form the bulk of most users' traffic back to the Internet.
A CMTS will enable as many as 1,000 users to connect to the Internet through a single 6 MHz channel. Since a single channel is capable of 30-40 megabits per second of total throughput, this means that users may see far better performance than is available with standard dial-up modems. The single channel aspect, though, can also lead to one of the issues some users experience with cable modems.
If you are one of the first users to connect to the Internet through a particular cable channel, then you may have nearly the entire bandwidth of the channel available for your use. As new users, especially heavy-access users, are connected to the channel, you will have to share that bandwidth, and may see your performance degrade as a result. It is possible that, in times of heavy usage with many connected users, performance will be far below the theoretical maximums. The good news is that this particular performance issue can be resolved by the cable company adding a new channel, and splitting the base of users.

A It is an acronym for "Data Over Cable Service Interface Specification" - an industry standard that nearly all cable companies are adopting as they upgrade their systems. Being DOCSIS - compliant means your Cable Modem will work with virtually all upgraded cable systems in North America, should you ever decide to move.

A cable modem will provide you with rapid download transmission speeds. Downloading a file that would take one-half hour using a telephone modem connection will take only a few minutes with a cable modem connection.
A cable modem provides a continual connection to the Internet. Two-way cable modems do not require the use of a telephone line.
Your service will not be interrupted or receive external static since the outer layer of the cable line will not allow any noise to enter the transmission line.
As a high-speed medium, you will be able to view many different multimedia presentations---"live" or streamed---such as concerts, movies, etc.

A Network Interface Card, often abbreviated as NIC, is an expansion board you insert into a computer so the computer can be connected to a network. Most NICs are designed for a particular type of network, protocol, and media, although some can serve multiple networks. To be connected to the AT&T Broadband network your computer must have a NIC or a USB adapter.

Abbreviation of interrupt request line, and pronounced I-R-Q. IRQs are hardware lines over which devices can send interrupt signals to the microprocessor. When you add a new device to a PC, an IRQ is usually assigned to the new device automatically; however, sometimes you may need to set its IRQ number manually. Setting an IRQ manually specifies which interrupt line the device may use. IRQ conflicts used to be a common problem when adding expansion boards, but the "Plug-and-Play" specification has removed this headache in most cases.

An IRQ is basically a work order sent by a peripheral device to the microprocessor in a computer. A processor will interrupt the task it is performing and execute the new instruction provided by the IRQ. When the new instructions have been completed, the processor returns to its prior task.
An IRQ conflict occurs when two devices have been assigned to the same IRQ. Since multiple signals to the computer on the same interrupt line might not be understood by the computer, a unique value must be specified for each device
and its path to the computer. Please note that some peripherals can share the same interrupt, but many cannot.
To determine the particular IRQ
conflict you have on your PC:•Close or minimize all applications so you can access your desktop
•Right-click on the My Computer Icon
•Select PROPERTIES
•The System Properties window will appear
•Select the Device Manager tab
•Highlight computer by clicking on it once
•Select PROPERTIES
•A new window will appear
•Verify that you are working in the View Resources tab
•Put a dot in the radio button next to INTERRUPT REQUEST (IRQ)
•A list of numbers, 00 through 15, will appear with each number having either a designated hardware component using the corresponding setting or an available status
•Write down the listed IRQs and memory addresses in use by your system (you'll then be able to use this information to determine what IRQs and memory addresses are available if a conflict exists)
•Click OK to return to the Device Manager tab
•Verify that the radio button is selected next to View Devices by Type
•If your system has an IRQ conflict, the Device Manager will highlight the device with a conflict with an exclamation point inside of a yellow circle (to see each device listing, you may need to expand each device section under the COMPUTER heading by clicking once on the plus (+) sign next to the device name)
•If an exclamation point inside of a yellow circle appears next to any device, you may access more information about the conflict by highlighting the malfunctioning device and clicking the PROPERTIES button
•Once in the Properties window, click the RESOURCES tab
•The Resources tab provides resource settings and a conflicting device list which may help resolve the IRQ conflict
If you have identified
an IRQ conflict, you may want to consider one of the following actions:•If the IRQ conflict involves your Mediacom Broadband-supported NIC or resulted from the installation of the Mediacom Broadband software, please send Mediacom an e-mail. Have your IRQ list available so the customer care specialist can promptly assist you.
•Contact the manufacturer of the hardware component that has an IRQ conflict
or is not responding for technical support with their product.

How To Modify Your IE Security Settings
After reading how Cox internet, AOL and Netscape (and probably other services) all can insert themselves into your "local" security zone in Internet Explorer (thus bypassing your Internet security settings), you might be wondering if you can fix this if you find it has happened to you.
Here are some steps you can preform to repair the damage.
First, copy the current settings: Either make a full system backup, or simply write down whatever you see in the Local Intranet or Trusted Zone dialogs, including anything on "advanced" and "custom" tabs. Then simply highlight and delete the entries you don't want in those zones. By removing web sites from the Local Intranet or Trusted areas, you'll automatically be restoring them to the normal Internet Zone.
Next, reboot and try accessing web sites, especially any from the areas you just removed. If your Internet connection works--- and odds are it will--- you're all set. But if something isn't working, use your backup
or your notes to recreate the settings the way they were before.
Alternatively, you can restore the settings with greater security:
Recreate the Local or Trusted zone entries, but then use the "custom" tab to ratchet up the security levels for various browser actions. If you're unsure what a given action is or what it does, change the action's security setting to "prompt." That way, you'll be asked (via a dialog box) if your browser tries to take whatever action(s) you've set to "prompt." Over time, you can get a feel for what's going on; and can figure out what's OK to "enable" and what you may wish to permanently "disable."
If all this made your eyes glaze over, just do the first step: Make a backup or written copy of whatever's in your Local or Trusted zones, and then delete the items there. Chances are, everything will still work, but you'll be safer. And you'll still be able to restore what you deleted, should you need to in the future.

A virus is a program or piece of code that is loaded onto your computer without your knowledge and runs against your wishes. Viruses can also replicate themselves. All computer viruses are manmade. A simple virus that can make a copy of itself over and over again is relatively easy to produce. Even such a simple virus is dangerous because it will quickly use all available memory and bring the system to a halt. An even more dangerous type of virus is one capable of transmitting itself across networks and bypassing security systems.
Some people distinguish between general viruses and worms. A worm is a special type of virus that can replicate itself and use memory, but cannot attach itself to other programs.

Yes! You are susceptible to attacks whenever you are connected. Fast connections make attacks on your system very efficient. An attacker can try many different attacks in a short amount of time. The always on nature of high speed Internet access with technologies like DSL or Cable modems make you a very convenient target.
