Hi, I'm Pete. Welcome to JustAnswer! I'm reviewing your question now, and will post back with your reply ASAP.
Is the web page you are trying to visit hosted internally?
Can you let me know a little more about the network setup?
Are there different networks using the same intranet?
What IP ranges are you using?
Have you checked the IP address range being used is the same on both the older and newer Datalogic device?
Have you tried doing any resets, e.g. a cold boot or a clean boot?
Ok, try a clean boot next... A "clean boot" is a cold boot that causes the device to be restored to factory configuration. The Memor will reset to its factory configuration, clear the working RAM and initialize the file system. You will lose any applications and data stored in persistent flash memory. At the next startup the system will ask to recalibrate the touch screen.
To perform a clean boot, follow these steps:
Step 1 - Perform a Cold Boot first.
Step 2 - Quickly release all the keys when the screen goes black.
Step 3 - Within 1 second press and hold down the Esc and 0 keys until the left orange led starts blinking.
Step 4 - Release the Esc and 0 keys.
Step 5 - Enter 1 to proceed with the Clean Boot sequence.
