Are you losing the connectivity from the computer or the ISP? Do you have a Modem and are the link lights on or off (and do they stay on when you try to connect).  You need to start at the source and work to the computer to define the problem.  First be sure of connectivity to your Modem or router -- If this is Okay then replace the cable (cheap and quick) if all is well to the computer it must be in the computer setting -- the best place to start is searching network connection problems and following the direction to investigate the problem.   If you are using "cable" internet those thinks need to be reset all the time under certain circumstances (power everything down for 3 min. and start powering up from the source)

First check the cable ends (connectors) to see if they are in good shape. Sometimes power outages might damage electric devices overtime. When no connection is available, does the modem show any signs of problems, like red lights or no sevice.

The first thing you have to do is identify if the problem is the cable network, or your computer. It is definitely not the modem if you have replaced that already. If you have a laptop or know someone who does, try plugging the laptop in to see if it does the same thing. I am willing to bet that it will, leaving the cable system as the cause. The problem is that there are many factors that could be causing the issue....bad cable, bad connectors, bad splitter.. you will probably have to have a technician come out. Make sure that all of your connectors are tight and not just halfway screwed on. Also make sure your cable splitter says 5 - 1,000 MHz (1 GHz).

what type of modem do you have? are you using a router? make sure you sequence power cycle modem first then router and pc if you do have. if still not then isolate router and plug modem directly to pc- , and you  have speed stream 5100b or 4100 ( 5 LEDS) then open a browser (IE) type 192.168.0.1 - \nif you can't pull it up, disable any firewall or anti virus or check LAN making sure it's enabled\nit should open sbc effiecient network- \nif you have internet light on your modem - then it means your modem might be saing default username and password- if no internet light- do the following for wither of the 2 situation: \nclick advance button on the left- then connection configuration - usually it will be asking for the modem access code- then type the correct username and password- click restart and ideally it should connect you to the internet- \n\nif still not- try disabling any firewall or anti virus\n\nif still not- there could be an outage and you may have to call \n1-877-722 3755 - it's toll free\nbecause you might be having a 2 wire modem/ router and it's another story- lol

Swap the cable with a known good cable. Or you could use a cable tester. \nhttp://www.google.com/search?sourceid=navclient&ie=UTF-8&rls=RNWK,RNWK:2005-50,RNWK:en&q=cable+tester

Internal modems generally go into any free PCI slot, but I have to agree with the first poster- I have NEVER seen an internal cable modem.  Those have always been external devices- there are some which don't have Ethernet ports and only connect via USB  (which I'd avoid).  For a cable modem, you want one with an Ethernet jack- that way you can use a router if you want...

You need to buy a null modem cable, this is a cable with 2 9 pin D female connectors on each end. You attach each end to the serial / COM port on each PC. \n\nYou can then transfer files between them by running hyperterminal on both PCs and configuring the COM ports to the same parameters, try:\n\n9600 baud\n8 bits\n1 stop bit\nNo parity\nRTS/CTS hand shaking \n\nIncrease the baud rate settings on both PCs together until you start to get data errors. \n\nYou can use Z modem protocol in hyperterminal under the transfer menu to send files back & forth.\n\nIf both of your PCs have RJ45 network ports then a P2P network using a cat 5 crossover cable would be a much simpler solution.
