Hello. I am new to the thread and this is my first post. So recently, I tried to set up another guest account on my wifi router. The model I have is an actiontech 1900 nighthawk modem which supports the ability to create separate guest accounts. However, I am having difficulty creating a separate subnet. Whenever I do try to set up a new guest network, I am notified to pick a new subset different that isn't already in use. My goal is to completely separate the guest network from the first SSID. My router address is 192.168.0.1. In order to do what I want I need to fill out the correct information for the DHCP (DNS intervals), subnet mask (255.255.255.0), a gateway address, and then connect that to an IP address and hope it functions. My provider is centurylink. I am pretty new to networking and would like to be run through the steps as well as where to go within the settings. Any help will be appreciated. Thank you.

The subnet mask is what is used to focus in on the part of the IP address of which determines the network it belongs. In your example, 255.255.255.0 is a class C and sets the 3rd octet as the part of the IP address which defines the network address. In your case 192.168.0.0 is the network address. So any IP address from 192.168.0.1 to 192.168.0.254 area all part of the same subnet or network.

To set up a proper guest network, you need to define IP addressing to be on a different subnet/network than your main LAN network. If you want to stick with class C 192 addressing, just change the 3rd octet to any number between 1 and 255. So if you set the guest network to use 192.168.100.0 with a subnet mask of 255.255.255.0, then it will be on a different subnet than your 192.168.0.0 LAN network. You should also be able to use a class A or B non routeable address space such as 10.0.0.0 or 172.16.0.0.

Thank you for responding to my post. Can you provide me with a specific code.
Here is my information on the main network:
Modem IP address: 192.168.0.1
Beginning DHCP address: 192.168.0.2
Ending DHCP address: 192.168.0.254
Subnet mask: 255.255.255.0
To set up the guest account I need to enter values for these:
DHCP start address:
DHCP end address:
SSID subnet mask:
SSIDgateway address:
Please respond. Thank you.
