daisy chained routers

[jimjim1]

Does the errant box get an address when plugged into the inside of the new router?

What are the addresses and subnet masks in each case?



Step TWO if it doesn't get an address from both -

Please:-

Get a pc and connect it to the two networks in turn using a cable. Make sure it is working.

Then from each network, noting WHICH is WHICH please, post the output from the following command
ipconfig /all
for the relevant interface. The example below shows a wireless one but yours will probably be called "Ethernet ..."

C : \Users>ipconfig /all

It will look like this

You can cut/paste out of the command window or if you are having trouble with that you could do screenshots. [Alt]PrtSc does a screenshot of the current window.

If you had to type it all in I guess the essential info is :-

Make SURE you get info from a WIRED interface.

IPv4 Address
Subnet Mask
Default Gateway
DHCP Server . .

but a machine copy would be much better.
