Model: Archer GE800  
Hardware Version:
Firmware Version: 1.3.2

Just bought a new GE800 and BE00.  Don't know the hardware version.

 

I want the GE800 to allocate DHCP address in the 10.0.0.x range. If I turn off my Comcast modem DHCP server my understanding is that the Comcast modem will be accessible as 10.0.0.1.

 

Right now the GE800 DHCP server gives out address in the 192.168.0.100-253 range, with gateway 192.168.0.1. The LAN address is set to 192.168.0.1 - they are both on the same network.

 

If I try to set the DHCP server to give out 10.0.0.x addresses I get the error "WAN IP Address and LAN address cannot be in the same subnet". If I change the LAN address to 10.0.0.1 I get the error "The IP address pool and LAN IP address should be in the same subnet". Messages totally conflict.

 

However both are in the same 192.168.x subnet with no errors.

 

What am I missing?

  @Caprichoso The Subnet is set by the 255.255.255.0 or 255.255.252.0.  The meaning of 255 means that that triplet needs to be the same 192.168.0 and 10.0.0 are not the same.

 

You should be able to access the Comcast gateway with 10.0.0.1 have you tried?

 

What it is specifically referring to when you change the IP from 192.168.0.1 to 10.0.0.1 is that the DHCP server is not yet changed from 192.168.0.x - 192.168.0.xxx to 10.0.0.x - 10.0.0.xxx.

 

But it is not a good idea to set the LAN IP to the same as the Comcast gateway otherwise you'll lose access to the gateway.
