The problem of not being able to connect to WiFi can be checked through the following steps: 1. Check whether the router and device are normal, such as power on, indicator lights, WiFi switches; 2. Make sure the password is correct, pay attention to uppercase and uppercase, uppercase and lowercase characters; 3. Handle IP address conflicts, reconnect or set to DHCP mode; 4. Improve signal strength, get close to the router or use an extender.
The problem that many people will encounter is that they cannot connect to WiFi. Don't rush to restart the router, first check out what the problem lies.

Are the router and devices normal?
Sometimes the problem is not the network itself, but the device or router has a minor problem. for example:

- Is the router powered up? Is the indicator light blinking normally?
- Are the WiFi switches on your mobile phone and computer turned on?
- Can other devices be connected to this WiFi?
If other devices can be connected, the problem is most likely to be your device; if none of them can be connected, it may be a problem with the router.
Have you entered the password correctly?
This is the most common "low-level error", but it does happen frequently. Pay attention to the following points:

- Is there case confusion?
- Did you type more or less?
- I have connected before and forgot, but now the system may have automatically filled in the wrong password when reconnecting.
It is recommended to enter it manually again, especially after changing the password.
IP address conflict or acquisition failed
Many connection problems are actually because of the IP allocation error. You can try:
- After forgetting the network, reconnect and let the device re-acquire the IP
- Set the IP to "DHCP" mode in the WiFi settings of your mobile phone or computer (that is, automatic acquisition)
- If you are a corporate or school network, you may need to contact an administrator to configure a specific IP
This problem is not easy to detect, but it is actually not difficult to solve.
The signal is too weak or the distance is too far
If you are too far away from the router, or are separated by too many walls, the signal strength may not be enough to stabilize the connection. You can observe:
- Are the WiFi icons only 1 to 2 boxes?
- Change the location close to the router and try to see if it can be connected
If the signal coverage at home is not good, you can consider adding a WiFi extender or changing to a router with stronger signals.
Basically these common reasons. If you check one by one, you can do it in most cases. If you really can't restart the router, maybe it needs to "wake up" too.
