Hello All;

   Due to our ISP not upgrading there system for faster bandwidth.

   Our ISP has just given me an Extra Modem to test a dual Connection
For Doubling our Speed on our Business Account.

  I have the extra modem already sync'd from our ISP.

Now I need to find out if it will connect to our PIX 501?
And how I need to go about doing this?

Thank You

I heard that it should work, but I need to have the wiring of the modems to connect
To the router to be the same as the [Orange] Cable for the PIX 501.

Could someone please give me a diagram of the Wiring colors for the Orange Cable?
This is very important to be able to test it.

I tried looking at the colors of the wiring through the Connector of the Orange Cable.
But was unsucceful at seeing all of the colors.

Thank you all

Tested and nothing worked.

3 Split off Cable.
1 - PIX
1 - Cable Modem #1
(Just the above 2 coming off from the 3-way split cable works)
1 - Cable Modem #2
(With both modems connected to the PIX the [0] (in) Light, instead of a Steady Green
It flickers a little more then usual.
And in the Console it shows the [Outside] as up, then after I "Refresh" a few time.
It goes to: Outside [Down]

Any idea's on how to connect 2 modems to the PIX 501.
I would be truely grateful.

Thank You all

Assign two address pools  one for each modem

  So i will need to add another Switch into the network?

Right now this is what my network looks like.

 D-Link DSS-24+ Switch

So in order for the Dual Modems to work.
Can you suggest a Switch to get.
Money is tight, and I would hate speed a lot of money and it still not work.

( I will ask you about this information here:  Assign two address pools  one for each modem
   After getting another Switch into the Network)

Thank You

(We have 12 - Static IP's with our Commercial Account)

I have just been informed by our Sales Rep. the following information:

The Static IP's are assigned to the 1st Modem.
How would be go out doing this?

Once we test the 2 modems together, and everything runs fine, and the speeds jump up.
Would we need to get them to split the IP Address's between the 2 Modems?

To Have The Following:

Modem#1 = 6 Static Ip's
Modem#2 = 6 Static Ip's


Also, on the "Switch" that the 2-Modems would be attached too.
Could you please let me know what type of Switch this would be?

As the Switch that we have right now that the "PIX" is connected to to split to all the
The PIX just connects into "Port 1" on the switch.

On the other Switch, Would the cable modems just connect basically the same way?

Thank you and please reply soon.
As we are needing to give this thing a test drive as soon as possible.

Thank You

I have been doing some reading about the interface that is available in WinXP : Bridging Internet Connections
To Double the speed.

  Since that is the case with the XP being able to do this on its own.
Would it be safe to say that I would need to get a "Switch/Bridge" For our setup here?

I found this unit:

The CNet PowerSwitch CNSH 1600
Which is a "Switch/Bridger Hub"

For the price and for testing, this looks to be right resonable.

If this is what I would need, please let me know?
So that I can go out and pick it up tomorrow?

Thank You

  I gave you a C: Average grade on this one.
Due to the fact that you never came back in to assist any further
With this issue.

  I have still not completed this task yet, But have the hardware.
And our ISP is going to split the IP Address's between them tomorrow.

So I am hoping that your little information here
And the information from another person (Of whome has never replied back
To assist further) will actually work.

Take Care and good luck
