Is the connected signal relatively weak? Try to get closer to the signal source and connect when the signal is better; 6. Connect the wireless network card to your own wireless network correctly; 7. Confirm your security type and key; 8. Turn off wireless MAC address filtering.

The wireless network at home suddenly becomes unavailable for the following reasons:

1. Check whether the password is wrong

When entering the wireless connection password , if the password is relatively long, you may enter the wrong password, so it is recommended that you enter the password again. If possible, enter the password directly using the copy-paste method. When copying and pasting, be careful not to select irrelevant characters. Adding one or two extra spaces is the most common mistake.

2. Whether the wireless router has been bound to the MAC address

In order to prevent others from using the Internet, many home users have set up wireless Mac address filtering, but after changing the computer or wireless network card, I can’t get online, so I need to add a new MAC address to the router settings.

3. Whether the service settings are completely correct

Check the service settings on the computer. For example, if the DHCP Client and WirelessZero Configuration services are not started, it will cause the wireless network to use unusual. If DHCP is not turned on, computers using automatically assigned IP cannot automatically configure IP addresses.

4. Is the assigned IP address set correctly?

The wireless network uses manually assigned IP addresses and DNS addresses. This needs to be set in the wireless connection properties under Windows. Unlike Windows and Linux, you cannot set different IP addresses for different wireless networks. Therefore, when switching between multiple wireless networks, you will easily be unable to access the Internet if you use a manually assigned IP.

5. Is the connected signal relatively weak?

If the signal is weak, the connection may not be successful. Try to get closer to the signal source and connect when the signal is better.

6. Whether you are connecting to your own wireless signal

Log in to the router management interface via wired access and check the SSID number in "Running Status" - "Wireless Status". If the SSID number is not the network name of the wireless connection, if not, please connect the wireless network card to your own wireless network correctly.

7. Confirm your security type and key.

Log in to the router management interface through wired access, check the security type set by the router in "Wireless Parameters (Wireless Settings)", and remember the key.

8. Is wireless MAC address filtering set up in the wireless router?

Log in to the router management interface via wired access, "Wireless Parameters (Wireless Settings)" - "MAC Address Filtering", confirm that it is turned off state.
