Screenlogic I changed out new routers but locally it will not connect

Appreciate the replies - I know a little more than average about networking but I'm NOT a CCNA for sure. I changed my network to class A primarily to get an entirely different range of IP addresses when I moved so as to see easily anything left from my old network which was the more typical 192.168... setup. the 255.255.255.0 was how it defaulted and from what I understand (and is mentioned above) there is no downside to doing this other than limiting it on available IP and 250+ is more than I need at this point.

Hate to get too far off topic, but if I change it in my router to the correct 255.0.0.0 as you note, is there anything that will break??? (the enemy of good is better).

I'm not aware that you can set a static IP for the SL adapter - you can set within your router a reserved IP for the MAC address, but I don't think the adapter has an interface in which you can set a static IP. Am I missing something?

Yes, the SL IP can be fixed using the ScreeLogic Connect software. Within the startup dialog, there is a "Configure IP Info..." button.

I've never bothered with the subnet mask, I've always used 255.255.255.0. To be honest, I don't even know what that's for.

My new mantra: "the enemy of good is better." Love that. I bump up against that all the time! Less condescending than K.I.S.S. I've been using "Sometimes good enough is good enough."

The subnet mask tells your devices which of the 4 octets are part of the IPv4 network number and which are part of the device address. So 255.255.255.0 says the first 3 octets are the network number and the 4th is the device address. Similarly, 255.0.0.0 says the first octet is the network number and the last 3 octets comprise device addresses. Strictly speaking, you don't have to use 255, that's the mask for all 8 bits of the octet and is most commonly used.

Nothing will explode if you change the subnet mask, but you will have to change it in every device for consistency.

You said you only changed the wiring to the switch. Did you change the DHCP IP address range from 192.xx to 10.xx when the Screenlogic problems occurred?

Nothing will break. You will get a larger address IP address pool. But your DHCP IP adress range will still be limited by the upper and lower IP address range you specify.

Devices getting the subnet mask from DHCP will self correct and get the new subnet mask. Any device with a static IP will need to have the new subnet mask set in it.

No the change in DHCP was several months ago. Screenlogic was stable on the 10.0.0.1 network for months. All I did was relocate wiring and add a new switch, no router changes when this happened.

Ok IP addressing I can speak to.
You can use any subnet mask and since 10.0 is part of RFC 1918 you can do anything you want. To make it less confusing I use 10.10.1.x/24

I am assuming it talks back to the internet so check the FW settings on your new router if it's still not working
