Here are some tips to improve the performance and communication between the Server computer and the Terminal, improving the quality and speed of the Nex on the local network.
Make sure you are using Nex on its latest version.
1.1 Click on ABOUT NEX, at the bottom left of the screen.
1.2 Click on UPDATE.
The Server computer and the Terminal communicate via their local network. Therefore, the quality of the connection depends almost exclusively on the quality of your local network.The ideal is to always have all computers connected to the local network via network cable. As the signal travels through the network cable, any type of external interference will have a reduced impact.
The Wi-Fi connection can suffer a lot of interference from other electronic devices in your store and from your neighbors' Wi-Fi signal, in addition to depending on the distance and number of objects — walls, for example — that are between the router and the computer, affecting the signal and speed of communication between computers.
In some cases, Windows itself and the lack of user permissions can interfere with the Nex's network performance. Therefore, it is necessary to allow great access to the Nex folder on all computers on the local network.
3.1 Locate the Nex folder on your HD. By default, Nex is installed in the C:\Nex folder. If you can't find it, you can check on NexServer where Nex is installed.
3.2 Right-click on the Nex folder and select the PROPERTIES option.
3.3 Uncheck READ ONLY and click on APPLY.
3.4 Click on SECURITY.
3.5 Click on EDIT.
3.6 Click on ADD.
3.7 Enter EVERYONE and click OK.
3.8 Check the FULL CONTROL option in the ALLOW column lick on APPLY.
3.9 Click on OK.
3.10 Click on OK.
Windows Firewall can interfere on the communication between the two computers. Let's create a new rule to allow the communication port used by Nex.
4.1 Type FIREWALL in the start menu and click on FIREWALL AND NETWORK PROTECTION.
4.2 Click on ADVANCED SETTINGS.
4.3 Click on INBOUND RULES.

4.4 Click on NEW RULE.
4.5 Check the option PORT and click on NEXT.
4.6 Check the option TCP, enter 17200 in the SPECIFIC LOCAL PORTS field and click on NEXT.
4.7 Click on NEXT.
4.8 Click on NEXT.
4.9 Type NEX PORT in the name field and click on FINISH.
4.10 Do the same procedure again in inbound rule, but now select UDP and enter 17200 in the specific local ports field.
4.11 Click on OUTBOUND RULES and follow the same previous steps to set the TCP and UDP PORTS as 17200.
It is important that this procedure is done on all computers that use Nex.
In some cases, it may be the Internet Modem itself or Windows blocking something.
5.1 Restart your internet modem. To do this, turn off the modem, remove all cables, wait 30 seconds and connect everything again. Wait for the internet signal to be reestablished and try again.
5.2 Restart the Server and the Terminal computer.
Done! With these tips, the Nex's network performance should improve, with the network cable being the most important.
