Mediacom currently advertises:

Standard: 8000/512
Max: 15000/1000

If you need help tweaking, please visit the BroadBand Tweaks forum for TCP/IP tweaking assistance. Modifying your configuration to maximize performance is known as tweaking.

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.
