You folks have always time and time again helped me successfully with various issues and I want to wish you all happy holidays.

For next year I am planning to boost my household backbone. I have a 2 station P2P LAN connected by a Linksys 4 port DSL/Cable router, being fed by a Comcast supplied Toshiba PCX1100 Cable Modem.

My plans are to upgrade my switch and Nic Cards to 10/100/1000(copper) because of how reasonable the
pricing seems to be, and my cabling to CAT6.

I was wondering if anybody knows/has hear if they are making a cable modem that can feed more bandwidth then what it currently produces.

Or is there a way to trick it? I would like to see if I could boost my internet connect, as close as I can to my LAN connection, without getting into the "T" thing.

Thanks in advance,

Jeff

 
Check the RWIN and MTU values on all workstations:
For cable systems there is little you can do if your neighbor's kids are big users of peer-2-peer software.

You might consider using DSL instead, as it is fundamentally a more dedicated service.

Finally, see if a fiber option is available. My neighborhood gets lit early next year with fiber by Verizon, and I can hardly wait. My DSL service should go from its current 3mbs down /768 up to something in the order of 14 mbs down /1 mbs up.
 
Nah, DSL would be a step back for me my friend. I'm not close enough to the co-location to warrant that kind of change.

I know people VERY close to it that seem to do better than cable, but overall cable is the better solution. I appreciate your input but it is not what I'm looking for.

Does anybody have a clear cut opinion on this, based upon what my question was?

With appreciation,

Jeff
 
To answer your first question. YES. DOCSIS 2.0 cam out last year (I think) and the new cable modems have support for HIGH speed data xfer. For on demand services, etc. The spec can be had by googling DOCSIS 2.0 and cable model or such...
 
Remember that your BEFSR41 has only a 10mbs connection to the cable modem.

Remember that your cable modem could well be restricted to a 10mbs port unless you replace it.

If internet access speed is your concern, the slowest point in your network controls all. Your CAT6 and 10/100/1000 are plans are unlikely to yield any benefit for the internet. They would help, depending on your base setup now, any LAN transfers between workstations inside your home.

I was wondering if anybody knows/has hear if they are making a cable modem that can feed more bandwidth then what it currently produces.

I hope you realize that in a cable system the configuration of your modem is done by the cable company each time the modem is reset. DOCSIS 2.0 has been out for a while, but it does not matter what standards your modem supports. The essential speed characteristics of the modem are determined by your cable ISP, and there is not legally (nor practically, they will soon discover any change by the user) a way to circumvent or speed-up your current service. You could bring out the cable technicians and have them test your RG-coax cable from the pole to the modem. There is a lot of old RG-62 out there. They can read the noise values and you can ask to be re-cabled to the modem with RG-59 brand new if the values are marginal.

But no replacement modem is going to help. No new switch or changing network adapters is likely to help. If your service is uneven, and you complain often, the cable company should start monitoring your loop for an excessive user. As I said in my original post, all you need is one or two 14-year-olds running Bit Torrent or eMule or LimeWire and downloading terabytes per month to screw your local loop big time.
