How to fix unstable or slow wireless network 
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 4:Change the wireless security mode and the encryption 
Solution 5:Power cycle the Tenda device and your computer 
Solution 6: Manually assign a proper IP address for your wireless device 
Solution 7: Disable the power saving feature of the wireless adapter 
Solution 8: Check your antivirus program 
Solution 9: Upgrade to a newer firmware 
Solution 10: Extend the Wi-Fi coverage when using wireless device far away from the Tenda 
device 
 
 
 
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

incompatibleissue.

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.

For a Tenda device, you can selectWPA-PSK, WPA2-PSK, Mixed WPA/WPA2-PSK, WPA

Personal, WPA2 Personal or Mixed WPA-WPA2 Personal as the Security Mode/Network

Authentication.

Click here to find instructions on setting up WPA or WPA2 personal wireless security on a

Tenda wireless device.

Note:You’d better select AES as the WPA-Algorithms/Cypher Type/WPA Encryption.

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

Step 1:

Unplug the power adapter from your modem first, then the Tenda device. Shut down your

computer.

Step 2:

Power on the modem first, then the Tenda device, wait for its lights on, and then turn on the

computer.

To get a stable wireless connection, you’d better disable the power saving feature of the wireless

adapter.

Here we take a Windows 7 computer for example.

Step 1:

Right click on Computer, select Properties, and then click Device Manager.

Step 2:

Point to Network adapters and find your wireless network adapter.

Step 3:

Right click on your wireless network and select Properties, switch to Power Management tab

(see screenshot below):

Step 5:

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.

After you have tried all the above-mentioned solutions but in vain, you can try to upgrade the

Tenda device’s firmware if any bugs exist.

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.

What if I cannot log into Tenda web-based

setup page

The login problem may be caused by different factors. Following the solutions below will

help you resolve this issue. Except A5 and 3G186R, it is highly recommended to

connect your computer to the Tenda device via an Ethernet cable to smooth the whole

process.

Note: Ensure that the login IP address you typed in the address bar is correct, as

well as the login username and password if any.

Solution 1 Check the hardware connections and the LED status on the Tenda device

Solution 2 Ensure that your computer has obtained a proper IP address

Solution 3 Change another web browser or delete cookies on the web browser

Solution 4 Reset the Tenda device to factory default

Solution 5 Power cycle the Tenda device and your computer

Solution 6 Update the driver of your computer

Step 1:

Take an Ethernet cable to connect your computer with one of the yellow LAN ports of

the Tenda device.

Step 2:

Ensure that the light corresponding to the LAN port where the Ethernet cable is

connected to is lit. If it is lit, you may proceed with the next solution. Otherwise, try to

connect your computer to another yellow LAN port or change another Ethernet cable.

Note:

There is only one LAN or LAN/WAN port on some devices like

A5/A6/A3/A30/N3/PW201A, etc. For A5 and 3G186R, you can only log into the

setup page wirelessly.

To ensure that your computer has obtained a proper IP address, click on here, you can

find instructions for each operating system:

Note: You may need to proceed with the next solution if you still cannot login.

i. Try to use another web browser to login, e.g. if you are currently using Google

Chrome, try Internet Explorer or others.

ii. Delete cookies on the web browser. Here we take Internet Explorer for example.

Step 1:

Launch the web browser.

Step 2:

Click the Tools button,point to Internet Options.

Step 3:

Check “Delete browsing history on exit” and click on Delete.

Step 4:

Check all the items in the following picture and click Delete.
