It is not rare that people experience unstable or slow wireless networks. A variety of things can bring wireless interference, such as wireless interference, wireless security mode incompatible, overloading, etc.This article will provide you with solutions on troubleshooting an unstable or slow wireless network.
Solution 1: Position the Tenda device in an ideal location
Solution 2: Disconnect some devices
Solution 3: Change the wireless channel
Solution 5: Power cycle the Tenda device and your computer
Solution 8: Check your antivirus program
Solution 9: Upgrade to a newer firmware
Your wireless router’s position can affect your coverage area and the strength of your signal. If you have a modem, you don't have to have the router in close proximity to your modem. Ideally, a Wi-Fi router should be in a central location.
Quick tips to position your router for the best signal:
i. Place the router in the middle of your house. If you place the router in a room off to the side of your house, you won’t get as strong a signal on the other side of your house.
ii. Position the router’s antenna vertically, so that the antenna is standing straight up. Antennas can be adjusted and lie horizontally, but standing straight up is generally the ideal position.
iii. Elevate your router away from floors. You’ll get better reception if the router is on a desk, not on the floor.
iv. You should also pay attention to the kinds of materials the router is near. For example, placing the router on a metal desk or up against a metal wall will cause problems. Signals can travel through a wood desk easily, but metal will obstruct the signals.
Note: A variety of household appliances may cause wireless interference. Depending on the position of the Tenda device, your networked device, and the appliance, you may even have the wireless network cut out when your microwave or cordless phone is in use. Plus, older Bluetooth devices can interfere with nearby Wi-Fi signals, although newer Bluetooth devices don’t. Ensure that microwave isn’t between the Tenda device and your wireless devices, in this way, problems with microwaves can often be solved.
The Tenda device might be too busy to respond to new requests if there are several computers or devices using it. If you have other wireless devices that are connecting to the network, try temporarily disconnecting them.
Interference from other wireless networks in the area can cause issues with your wireless signal.
When multiple wireless networks are competing for the same channel, an unstable and slow wireless network comes. You can change the wireless channel to fix it. For instructions on changing the channel, click here.
Note: In the same page where you change the SSID, you can also fix the unstable or slow wireless network by changing the Network mode from 11b/g/n Mixed Mode to be 11b/g Mixed Mode.
Changing the security mode may be much helpful in resolving wireless security mode incompatible issue.
i. It is highly recommended to use WPA or WPA2 personal as wireless security modes. Other than providing better security, this will establish a stable connection with your wireless device, especially devices with the latest technology.

ii. Sometimes, the wireless security mode of the Tenda device is not compatible with your wireless device. You may need to disable the wireless security. This is especially true for older devices and Windows Vista computers.
Note: You can secure your Wi-Fi with Access Control once the security mode is disabled.
Manually assign a proper IP address for your wireless device, which must be within the same range of the router's IP address. For example, if the IP address of the Tenda device is 192.168.0.1, you can set a static IP address ranging from 192.168.0.2 to 192.168.0.254 for your wireless device, set the subnet mask to be 255.255.255.0, and set the default gateway to be the IP address of your Tenda device: 192.168.0.1.
An unstable and slow wifi may simply caused by overloading, you can power cycle the Tenda device, your computer and your modem if any
Unplug the power adapter from your modem first, then the Tenda device. Shut down your computer.
Power on the modem first, then the Tenda device, wait for its lights on, and then turn on the computer.
Here we take a Windows 7 computer for example.
Right click on Computer, select Properties, and then click Device Manager.
Right click on your wireless network and select Properties, switch to Power Management tab (see screenshot below):
Uncheck Allow the computer to turn off this device to save power, press OK.
Check your antivirus software, just turn it off to check. (Don't get mail or go to anywhere that a risk exists! Only surf only safe sites while doing this test, like Microsoft, Yahoo, Google, etc.) If you find the problem is caused by the anti-virus program, remove and install another one.
Note: Antivirus software often scans the transfer file and slows down the connection. You can turn if off before transferring something and make sure to turn the antivirus software back on after the transfer completes.
Note: You should extend the Wi-Fi coverage when using wireless devices far away from the Tenda device.
If you need to cover a large area with a wireless signal, one Tenda device may not meet your need. You can buy another Tenda router or extender, working as a wireless repeater or range extender to extend its Wi-Fi coverage.
Note: Depending on the Tenda device, you may be able to attach an improved antenna that gives your signal additional range.
