Is there a specific reason for setting the default DHCP IP address pool range from 192.168.#.100 to 192.168.#.200?

What if I left the pool from 192.168.1.2 to 100? Will it have a connection issue?

 

Also, do we need to change the IP Address in the LAN TCP/IP Setup, too?

 

I took a recommendation and set it like this below:

LAN TCP/IP Setup

IP Address

192.168.1.1

IP Subnet Mask

255.255.255.0

(V) Use Router as DHCP Server

Starting IP Address

192.168.1.102

Ending IP Address

192.168.1.150

(I am starting 102 because I don't want to assign 100 and 101 that seems admin IP. This is just my preference)

 

I am wondering if I need to change the IP address from 192.168.1.1 to 192.168.1.100.

 

This firmware works better than old 1.x.x.x firmware for me. I had CAX30 in late 2022 with old firmware which continuously dropped the internet when I entered any device to Address Reservation. I ended up returning it. However, I recently purchased CAX30 again and installed 2.2.2.2 firmware and it is more stable.

    I found years ago that having a smaller default IP address pool size was better and worked better for router systems with smaller count devices connected. The system has less to deal with if you only have 30-50 devices all connected at once. yes you can change this range at any time. My preference as been to use .100 thru .150 for my range since I only have about 30-maybe 40 devices tops. Still has room for new devices. 

     

    You can use 192.168.1.1 as this IP address is the reserved IP address for any routers default web page access. So .2 and above can be used. I've never seen a .100 or .101 admin IP addressed web page for access here.

      Thanks for your reply.

      If I understood correctly, it is to limit the IP range instead of forcing it to use above 100 (to 200).

      Is it still OK if I set it to use 192.168.1.2 to 192.168.1.50?

      I was limiting only 50 IP addresses before on Nighthawk c7000v2 (I only have 40 devices)

    I don't think I have an issue after upgrading 2.2.2.2.

    As I mentioned earlier, I bought CAX30 from Costco and had issues with the 1.x.x.x versions so I returned it.

    I somehow got CAX30 again in 3/2024, and firmware 2.2.2.2 is working well.

     

    Let me share my current config and you can configure similar to it, and see if it works.

     

    Note: I am only sharing the configuration on the Advanced tab. Use a Desktop version of the web browser to access the Admin page.

     

    (o) means the radio button is selected.

    (v) means the checkbox  selected.

    ( ) means not selected.
