Is the LED screen I just bought so anxious that I can't connect to WiFi? It clearly shows that it is connected but it is stuck in PPT? Let’s teach you how to do this today. Don’t panic, follow the steps and make sure your screen is as smooth as if it is turned on with 5G hotspots!

1. Three steps to basic settings

​​Step 1: Find the control panel​​
Most of the WiFi modules of the LED screen are hidden in two places:

1. ​​Physical key zone​ ​: Find out if there are buttons with signal icons on the screen border. Press for 3 seconds and the blue light will be turned on.
2. ​​Remote Control Menu​ ​: Press "System Settings" → "Network Connection" → Just see the WiFi icon

​​Step 2: Match the intelligent system​​
There is a pit here to be aware of! Control software corresponding to different screens may be in conflict:

• Android system LED screen: Use​ ​LED Vision Controller​ ​(Recognize the blue icon)
• Windows system LED screen: Install​ ​SmartWall Configurator​ ​(The version must be ≥2.3.6)

​​Step 3: Frequency band selection metaphysics​​
How to choose 2.4GHz and 5GHz? Look at this comparison table:

2. Signal enhancement black technology

​​Question 1: The signal is obviously full but it is stuck? ​ ​
Eighty percent of it is channel congestion! Teach you two tricks:

1. download​ ​WiFi Analyzer​ ​(There are Android/PCs) Scan the peripheral channels
2. Adjust the screen channel to a value with a usage rate of less than 30%, it is recommended to choose the three golden channels: 1/6/11.

​​Question 2: Are outdoor screens often disconnected? ​ ​
Try these wild ways:

• Set a router​ ​Tin Foil Shield Cover​ ​(Don’t laugh! Really reduce signal interference)
• Post on the back of the screen​ ​Copper foil tape​ ​, enhance the antenna reception area
• Put the router 2 meters above the ground to avoid metal obstacles

3. Essential skills for advanced players

​​Self-built hotspot transmission secrets​​
Need to update ad content in real time? Take out your old phone and play like this:

1. Prepare the hot spot for the backup machine, set the name as​ ​LED_Control_5G​​
2. After connecting to hotspots on the screen, the speed of transmitting files using FTP tools soars by 3 times
3. Remember to change the hot password every month to prevent being rubbished

​​Factory-level debugging tips​​
If you encounter a situation where you can’t connect to the death, check it in this order:

1. Restart the screen power supply (wait for 30 seconds before turning on)
2. Reset network settings (don't be afraid of losing data, the content is in the cloud)
3. Updated firmware version (the screens after 2023 support OTA upgrade)

Last time I helped my friend debug the promotional screen of a milk tea shop, I encountered a weird thing - the screen is normal to connect to the Internet during the day, but it is fucked at night. Later I found out that the store’s neon light power supply interfered with the 2.4GHz band, and the problem was immediately solved by changing it to the 5GHz band. So, when you can't handle it, you might as well think about it from a different angle. Maybe the problem is not on the screen at all!
