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.

Security Question

Tags: NetGear, Wall plug Ethernet bridge, XE102
I have a network security question regarding a Netgear XE102 wall plug Ethernet bridge and a Watchguard SOHO 6 router. The main office has a cable modem, a Watchguard SOHO6 firewall, and the XE102. The XE102 is plugged into an electrical outlet and patched into the SOHO6. There are 10 other rooms that use the XE102 to get internet access only. My questions are: Does this setup provide enough security? Are all the XE102s isolated from each other or do I need to somehow tighten security?

What do you mean by isolated, from the outside?  My reading of what the XE102 does, all the systems that are connected to the XE102 are on the same network behind the soho6.  i.e. if one system is infected by a virus, the others could be infected as well.
My understanding is that XE102 uses the electrical wiring to establish a network.


 
03.13.2008 at 05:01AM PDT, ID: 21115195
So all the machines that use the XE102 are on the same network. Is there a way to put them on their own network via the Watchguard i.e. VLAN or subnet?
 
03.13.2008 at 06:58AM PDT, ID: 21116234
Not sure how exactly you are planing to "separate" the electrical wiring into different groups.  
http://reviews.cnet.com/adapters-nics/netgear-xe102-powerline-adapter/4505-3380_7-21057065.html references a utility that comes with the device.  Potentially you could have mutliple XE102s configured with different security codes.  The problem is the data from all is on the same wire.  I do not believe VLAN by security configuration is viable on powerlines.

Lets start from the begining, what are you trying to prevent?
The purpose for the XE102 is to setup a network to share a single Internet connection without the need for running network cables all over the place.
Accepted Solution

I thought there was a way to keep all the computers using the XE102 separate from each other. From your link, I now understand that they are all on the same wire. The encryption utility looks like the best way to secure the devices. Thank you for all your help.
