What can I do if the wireless network is unstable via my wireless router/modem router?

 Precondition: 

1. Please check whether the internet is stable or not when the computer is connected to the TP-Link router/modemwith a cable. If not, please try to change the Ethernet cable, LAN port and computer to carry out a test. Also, you can refer to the following link to upgrade the firmware of your router/modem if it is not the latest one.

2If you have a modem from ISP and a TP-Link Router.Please make sure that when the computer is connected to your internet modem, the internet works fine without dropping. If the internet is not stable with direct connection to your modem, please contact your internet service provider to do some troubleshooting. 
 
Symptom:
Wireless devices intermittently disconnect from the wireless network, while wired devices are still connected and working ok. And the firmware of the router is already upgraded to the latest one.
 
Cause:
In most cases, this problem is caused by local environmental factors that affect the wireless signal.
 
Resolution:
1. Locate wireless clients in a reasonable distance. The farther distance away from the router, the weaker wireless signal will be. Try moving closer to the router to see if the connection improves.
2. Get away from obstacles. Keep the router in the most central spot in the home and away from anything that might block its signal such as metal objects, bodies of water, reinforced concrete walls, foil-insulated walls, and other similar construction materials may severely weaken a wireless signal passing through it.
3. Reduce the number of wireless clients. The more devices are sharing the wireless network, the less bandwidth is available for each device to use.  One or two devices may be 'hogging' bandwidth. Try disconnecting some of the devices to improve performance on other devices. You may carry out the test by add one device each time to wireless network to check the maximum value of wireless clients in your network environment.
4. Decline interference from other wireless equipment. All wireless devices are trying to send data over the air. Cordless phones, baby monitors, Bluetooth devices (i.e. wireless speakers, mouse) and neighboring wireless networks are all competing with the wireless network. Move Wi-Fi devices away from other transmitting devices, or turn them off when they are not in use.
5. Place the router in a better way. For routers with antennas mounted on the outside of the casing, try adjusting the orientation of the antennas for maximum performance.we recommend placing it up high and also placing its antennas at 45 degrees (diagonally) or 0 degrees (straight out parallel to the floor), which will be more effective. Since antennas always transmit weakly at the base, do not place your wireless client device at the bottom of TP-Link wireless device.
6. Change some settings on the TP-Link router/modem. If the issue still persists then you could try changing some wireless settings on the wireless router/modem
 
Please click on your product category for guidance to change the wireless settings:
 
 
 
For Wireless Routers:
1)Log into the router’s web interface.
 
2)Go to Wireless-Wireless Settings(Or Wireless 2.4GHz-Wireless Settings on dual band wireless routers),select the correct Region/Country. If it is set to a different location from you, then you may come across similar issues with the wireless disconnection.
 
3)Try different wireless channels.
Channels 1,6 and 11 are generally best, but any channel can be used. You may use a free software, called inSSIDer, to detect the idle channel. And also, change the channel width to 20MHz which will provide you a more stable and less crowded wireless environment-Save
 
4)Go to Wireless-Wireless Security.Choose the most secured encryption to avoid others connecting to your wireless.The recommended encryption is WPA/WPA2 Personal(also called WPA-PSK/WPA2-PSK)-Save
 
5)Go to System Tools-Reboot-Reboot the routers to save the settings,test the wireless connection again after the router is rebooted.
 
 
For ADSL Modem Routers models:

1) Log into the web interface of the modem.
2) Go to Interface Setup-Wireless- select the correct Region/Country. If it is set to a different location from you, then you may come across similar issues with the wireless disconnection.
 
3)Try different wireless channels.
Channels 1,6 and 11 are generally best, but any channel can be used. You may use a free software, called inSSIDer, to detect the idle channel. And also, change the channel width to 20MHz which will provide you a more stable and less crowded wireless environment-Save
 
 
 
4) Go to Interface Setup-Wireless.Choose the most secured encryption to avoid others connecting to your wireless.The recommended encryption is WPA-PSK,WPA2-PSK or WPA-PSK/WPA2-PSK(Mixed) ,Encryption AES-Save
 
5)Go to Maintenance-SysRestart-Restart the modem with Current Settings to save the settings,test the wireless connection again after the modem is rebooted.
 
 
For ADSL Modem Routers models:TD-W8950N ,TD-W8950ND, TD-W8960ND, TD-W8960N,  TD-W8960NB, TD-W8910G, TD-W8920G, TD-W8968 V3
 
1) Log into the web interface of the modem.
2) Go to Wireless-Basic- select the correct Region/Country. If it is set to a different location from you, then you may come across similar issues with the wireless disconnection-Apply/Save.
3)Go to Wireless-Advacned,try different wireless channels.
Channels 1,6 and 11 are generally best, but any channel can be used. You may use a free software, called inSSIDer, to detect the idle channel. And also, change the Bandwidth to 20MHz which will provide you a more stable and less crowded wireless environment-Apply/Save
 
 
 
4) Go to Wireless-Security.Choose the most secured encryption to avoid others connecting to your wireless.The recommended encryption is WPA-PSK(better),WPA2-PSK(best) or WPA-PSK/WPA2-PSK(adaptive) ,EncryptionAES-Save

7. Test the WIFI device. If all other devices are getting continuous wireless connection, but some individual device is suffering from an intermittent wireless network, it may due to the device itself that can’t function well.
Please try to take it somewhere else to check the performance of wireless connection, or just try to update the system or wireless adapter’s driver to latest one to see how it goes.
