Flow network setup check for Windows - Logi Options

If you are having difficulty establishing a connection between two computers for Flow, follow these steps:

1. Check both systems are connected to the internet:
   • On each computer, open a web browser and check the internet connection by navigating to a webpage.
2. Check both computers connected to the same network: 
   • Open a CMD prompt/Terminal: Press Win+R to open Run.
   • Type cmd and click OK.
   • In the CMD prompt type: ipconfig /all
   • Check and note the IP address and Subnet mask. Make sure that both systems are in the same Subnet.
3. Ping the systems by IP address and make sure that ping works:
   • Open a CMD prompt and type: ping <IP address>   [Where the <IP address is the IP address of the other computer noted in step 2 above].
4. Check that the Firewall & Ports are correct:
   Ports used for Flow:

   TCP	59866
   UDP	59867,59868

   • Check the port is allowed: Press Win + R to open Run
   • Type wf.msc and click OK. This should open “Windows Defender Firewall with Advanced Security” window.
   • Go to Inbound Rules and make sure LogiOptionsMgr.Exe is there and is allowed
     
     Example: 
     
5. If you don't see the entry, it could be that one of your antivirus/firewall applications are blocking the rule creation, or you were initially denied access. Try the following:
   1. Disable the antivirus/firewall application temporarily.
   2. Recreate the firewall inbound rule by:
      • Uninstalling Logitech Options
      • Reboot your computer
      • Make sure the antivirus/firewall app is still disabled
      • Install Logitech Options again
      • Re-enable your antivirus
