More Migration Issues

[BobH]

About 6 weeks ago I switched from cable ISP service to wireless (T-Mobile cellular) ISP service. This past week I've had to move to a new laptop due to the demise of my very old HP laptop. Since the switch I've been unable to get my Brother HL-2270DW printer and several wifi outlet plugs back in service.

Is there any way to 'see' what wifi devices with electrical power exist in my environment?

To see what's connected to your T-Mobile device use the T-Mobile Home Internet phone app. You can also use a tool such as Nirsoft's Wireless network watcher.

Thanks, Joe.

I'll look into that Nirsoft app. What I'm trying to do is to determine what devices there are that are emitting wifi signals that are not connected to my system. I will then attempt to connect each valid one, in turn.

With the WNW app, you may need to set the IP address range to scan in the advanced options.

Thanks, again, Joe.

I had trouble when I first tried to use it getting it installed. When I got past my feeble brain issues with the warning that Nirsoft is an unknown publisher to Windows11, I was able to finish the installation and run it with these results:

Now, where can I find a good MAC address interpreter?

One of the devices I was hoping to see is my Brother printer. It it's in the list, I don't recognize it. IIRC, IP addresses do not specifically identify devices but identify how they are addressed by the os and are dynamically assigned, which means that they might be different from time to time. Is that correct?

[JoeP]

You can try using either of these tools: DNSchecker MAC lookup or Wireshark MAC lookup. If you prefer an app NirSoft has MAC address lookup. You'll need to have the complete MAC addres. That column needs to be made wider in WNW to see it all.

And, yes IP addresses assigned dynamically can change but seldom do on home networks.

Thanks again, Joe!

That's great information. Thanks, again, Joe!!!

After reviewing the results I found that some of the MAC addresses I submitted weren't there. I tried again with the box checked to show Not Found in results and got this.

Use BrAdminLight to find Brother printers on your network

You can try the websites to see if they can find the ones the app won't.
