Do not understand some of how to enable bridge mode in Archer C8

Getting a double NAT problem from my Xbox One.  I have two, both connected by Ethernet to the router.   Router has all ports used, is connected to Cable Modem, which also has built in router.  

 

Instructions for Step 3:

 

Click Advanced > Network > LAN.  Change the LAN IPv4 to one on the main router’s subnet, then click SAVE
Example:  If the root router’s IP is 192.168.0.1 with an IP range of 192.168.0.2-192.168.0.100 you would set the TP-Link device to 192.168.0.101

 

 

IP Address is: 192.168.1.1  but there is nothing on the admin web page that tells me the IP range.   Am I missing it?

Sorry for the confusion.  So what you want to do is set the C8 to an IP in your modem/gateway's subnet.  Since the Default Gateway is 192.168.1.1 and the subnet mask is 255.255.255.0 you would set the IP as anything 192.168.1.2 to 192.168.1.254.   I would recommend to use an IP outside your DHCP pool of the Gateway, that way you do not accidentally create an IP conflict later.

 

 

Let us know if that helps

Carl, I appreciate your response:

 

......but how do I determine what is "an IP outside your DHCP pool of the Gateway"?

 

Do I need to contact my ISP for that or is there another way?

 

(Also I am very worried I am about to make a change to the router that could prevent me from getting back to the admin console.)

You will need to log into your ISP's gateway and look at the LAN DHCP pool.  and choose an address outside of that pool.  Your subnet is likely 255.255.255.0 which means the available address would be 192.168.1.2 through 192.168.1.254, so for example if your DHCP pool is 192.168.1.2 - 192.168.1.102  you could choose anything from 192.168.1.103 through 192.168.1.254.   

 

 

Hope this helps but let us know if you have further questions

 

 

 

Best Regards

It looks like the available addresses on the Cox Netgear Gateway C6250 are from 192.168.0.10 to 192.168.0.254, but I still don't understand the "LAN DHCP Pool".

 

I found the manual for this modem and this is what it says about that:

 

The default DHCP address pool is 192.168.0.10–192.168.0.254, with IP address
192.168.0.10 reserved for ReadySHARE. The first IP address that the DHCP server can
assign to an attached device is 192.168.0.11.

 

So does this mean (assuming I have never changed anything) that the available addresses and the DHCP address pool are the same and there are currently no addresses I can use outside the pool?     In fact, the only way to assign an address outside the DHCP pool is to edit the settings on the Netgear modem to change the pool?

 

Sheesh, I never dreamed having two Xbox One's was going to be so f--king complicated!

Hi sorry for the delay in getting back to you.  No there are still address available.  You can use any of the 9 addresses 192.168.0.1 though 192.168.0.9 as a static IP.  Although you may find it simpler to just put your Cox gateway into modem only mode and leave the Archer C8 as your router.  In fact looking at the techincal specs of that Gateway the Archer C8 is a better device.  It is an AC1750 vs AC1600 and has USB 3.0 and Beamforming capabilites where the Gateway does not.  

 

 

Best Regards
