Is there a method to fixably assign an IP address to a USB Ethernet adapter?
Is there a method to fixably assign an IP address to a USB Ethernet adapter?
Hope someone can help with this. We need to link to air compressor controllers while working. The compressor needs a specific IP address for the laptop to connect. We have workers who aren’t very tech-savvy. Because each vendor has its own IP, every time we switch to a different brand compressor the technician must manually set up TCP/IPV4. After some time they should remember the process, but currently they still ask me over the phone for instructions. Is there a method to assign an IP directly to the USB adapter? That way I could order three different adapters in various colors or brands and ensure the correct one is chosen without needing manual changes?
If I follow correctly, the USB network adapters might be set up with a specific static IP address as needed.
This:
"The compressor needs a fixed IP address for the laptop to connect"
Just to verify: Are you suggesting that air compressor manufacturers do not permit users to modify or reconfigure the default IP address on these devices?
Are all air compressors tracked through their IP addresses on another network, while the laptop is only used directly for accessing logs, maintenance, and testing from the air compressor?
Additional details are still required.
Is the necessary connection simply
Laptop connected via USB cable ===> USB network adapter ===> Ethernet cable ===> air compressor with a fixed IP of X.X.X.X and subnet Y.Y.Y.Y
With no other network links during service – correct?
Does the laptop remain on one network, either wired or wireless? Or will it be connected elsewhere later to upload air compressor data to another application after collecting information from the compressors?"
For instance, Brand one uses 192.168.100.1 while Brand two uses 192.168.200.1. These addresses are fixed from the start and cannot be altered.
The compressors operate independently and we only connect to them during service to retrieve logs and update firmware.
Connections are established through an ethernet cable to the compressor, as previously mentioned.
I would like to provide him with two USB adapters that are already configured for those IP addresses (not sure if this is feasible). Perhaps they differ in color or are labeled inside plastic bags. This way, he can simply remove the appropriate adapter and connect without needing to manually adjust the TCP settings.
You can utilize a portable router such as the GLi.Net models to accomplish this:
https://www.amazon.com/GL-iNet-GL-SFT120...B09N72FMH5
For instance, if the compressor is configured at 192.168.100.1:
Change the router's address to 192.168.100.10
Adjust the DHCP range from 192.168.100.150 to 192.168.100.200
Then everything works seamlessly—simply connect the compressor to the router via Ethernet and the laptop to the router using Wi-Fi or Ethernet. No adjustments needed, just let the router initialize.
You'll also need to purchase multiple routers, which are generally more costly than USB adapters.
My suggestion is to give a college student a few hundred dollars to develop a desktop application. It should feature three buttons displaying the logos of various brands. When pressed, the app sets the network settings correctly for each brand. Including a single USB adapter model (keeping spare copies) ensures continuity if they are misplaced.
Why? Since IP addresses function as software rather than hardware, this approach addresses their limitations effectively.
In line with the discussion, especially regarding the software nature of the IP address, there exists a PowerShell command to configure the laptop's network adapter IP.
It is noted that two desktop icons are required on the laptop—one for each compressor, labeled Brand one and Brand two.
Selecting the appropriate icon activates the laptop’s USB network adapter to connect to either 192.168.100.1 or 192.168.200.1, depending on the compressor being serviced.
Question: What subnet masks are utilized by the air compressors?
Based on the standard setup of two devices per network as shown in the diagram:
Laptop < === USB cable ===> USB network adapter <===Ethernet cable ===> air compressor with a fixed IP address of X.X.X.X and subnet Y.Y.Y.Y
After establishing the connection, vendor-provided applications (hosted on the laptop) handle log downloads and firmware updates.
This implies the laptop is linked to another network for receiving firmware updates and/or uploading logs. Is this accurate?
Hello everyone! Thank you all for your help!
The compressors have a subnet of 255.255.255.0.
I’d prefer to avoid using software since my company doesn’t allow any apps or programs on the laptops.
The router idea sounds good. It’s around $30, which seems reasonable.
However, this would be an application developed by the firm you are employed with. There shouldn't be any complications about that.
So an unusual approach might be to keep the main Ethernet active through DHCP. This should function well on typical networks.
Next, go to the advanced settings and enter secondary IP addresses. Click add and input the desired IP for each device on every network, using a mask of 255.255.255.0.
There may be some restrictions, but you should easily fit three IPs—one per network.
In practice, the interface appears on all subnets simultaneously.
This method works best in scenarios like yours, but connecting to standard networks can lead to problems.
For instance, linking a regular router to one of these networks would still rely on the secondary IP.
It generally works, though you end up with a fixed IP that could conflict with other devices.
Some network profile managers could assist.
