Can't link PC Companion and tablet - alsass - 03-21-2025

Hello, I am having problems connecting my tablet (Samsung/Android) to my PC (Windows 10) trhough Companion. As didn't worked initially, I tried to manually WIFI connect matching IP on both devices. Didn't worked either. Then I make sure to follow all the steps I read on this forum and still don't get the connection. I rebooted the router, checked that my firewall is not blocking Companion and make suere I have free ports such as 888, 16568 and 16569 and still don't get to connect.

Any suggestion or advise will be appreciated!

RE: Can't link PC Companion and tablet - Zubersoft - 03-21-2025

Are both devices on the same subnet, meaning they have the same first three octets of the IP address? (such as 192.168.1.X). Do you have a mesh router? If you connect both devices to a WiFi hotspot with your phone, and then try to connect, does that work?

Thank you very much Mike. Yes, I was trying to connect through a Mesh router. Used the hotspot instead and went through inmediately. .I am new with MSP and still in the process of learning but so far I am amazed with such a superb porduct MSP is. Congrats and thanks for the help!

I'm glad to hear that. If you can disable the mesh functionality, that might prevent the problem, otherwise it can be difficult if the TCP traffic is being blocked by the router.

If I could piggy back onto this as my problem is the same.

I too have tried all the steps.  I notice my tablet (chromebook) shows an IP address with different subnet (100.115.92.22).  When I connect to my local Wifi, chromebook reports connection to 192.168.68.119 which is the same subnet as my PC.

Is there a way to tell Mobilesheets to reset the subnet?

RE: Can't link PC Companion and tablet - Lawrie - 07-21-2025

That address is from the CGNAT "Carrier Grade Network Address translation" range: 100.64.0.0 - 100.127.255.255 Which is used by carriers (ISPs).

My guess is that your device has a sim and is using that to access your mobile carrier which is assigning that address.

When you connect via WiFi you get a local address from your router.

No sorry you're wrong, no SIM, just a plain ol chromebook that connects to WiFi.  As I said the IP of the chromebook is correct, just Mobilesheets showing the weird address

RE: Can't link PC Companion and tablet - Zubersoft - 07-22-2025

This is because ChromeOS places a firewall between Android apps and the network layer. So MobileSheets will report a different IP address than what is actually used. You have to ignore the IP address MobileSheets is showing and instead use 192.168.68.119 as that is the correct one. This won't stop the connection from working though. I still need to find time to switch to DNSSD so that the discovery mechanism can get around these kinds of issues.

Hello Mike,

Thankyou, yes that resolved the issue for me.

Can I just take this opportunity to say thank you for your product and great support.  I have been using mobilesheets since July 2018 with little to no issues.  Building collections, creating 2 or 3 setlists per week and using the editing tools where required.

great product, great support...

Hi,
I´m new to this.
I used MohileSheets Pro so far on an Windows system (Dell Convertible), now I boguht an Android Tablet Samsung Galaxy S10 Ultra. For this I bought a new Mobilesheets. Now I want to transfer my music from Windows to the new Tablet. The Tablet so far has got only a WIFI-Connection, no SIM-Card yet.
I tried some things, but nothing worked. Can I get help here?
Thanks!

Please watch this tutorial video: https://youtu.be/SPLhDxxBstg

It covers all the different ways you can move your library between devices. There are more tutorial videos here as well: https://zubersoft.com/mobilesheets/tutorials/

If you still run into issues, let me know. I think creating, transferring and restoring a library backup file is the best option.
