The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

DHCP and Webstar 2100 Cable Modem Problems.

Asked by tinkerphil in Computer Modems, Broadband Internet

Tags: webstar, modem, cable, 2100

Hi,

I have just moved house and started using a different Broadband provider (Virgin).

They have provided me with a Scientific Atlanta Webstar EPC2100R2 cable modem.

I have 2 off PC's running Win XP Pro.   A Dell 1710 mono laser printer and an Oki C3300 colour laser printer.  I have a SITECOM Nexthub HD050 connecting everything together on a 10/100 network.  

I install their supplied software, and I can then access the internet on this comuter ok.  However, part of the installation enables DHCP IP address resolution on my PC.  So it has changed my IP address from the 192.168.0.1 address I was using.

NOW I cannot talk to the other computer on my network, or the my printers because they are all using the 192 scheme and not my DHCP assigned IP address.  

I have tried changing all other devices on the network to be DHCP enabled, but they cannot see the DHCP server for some reson.

I have tried changing back to my old 192.168.0.1 and setting the Default gateway to be the Cable Modem IP address, but it cant see it, I cant ping it, the internet, or anything.

I have tried all sorts of things, without success.

Help!

Many thanks...
Philip.

ps.  when connected to the internet now...  if I do a IPCONFIG /all it gives me...
