With the increasingly mature network television network broadband, more and more families began to abandon the traditional TV, and then buy Internet TV, because with the network video, online movies, online games and other features that traditional TV does not have, Internet TV will need to connect Broadband network, and the home network is generally not just connected to the Internet TV, but also to connect a computer or smart phone, which must use a wireless router.
Common wireless network connection is not connected, unstable factors:
First, the network is not connected
1, built-in WIFI module failure, WIFI with line plug open circuit or TV system software bug. WIFI is not recognized. The WIFI option is not visible in the setup menu. The options are generally gray.
Error code 002004 indicates that: The wireless network card was not detected. This TV is wirelessly networked and requires an external wireless network card and wireless router. Similar network connection shows error code
2. The external wireless network card and the TV do not match (detection method: whether the wireless network settings can be seen in the network setting interface).
If the network TV uses an external USB wireless network card for network wifi connection, select the previous user guide to view, different brands of Internet TV compatible wireless network card is not the same, before buying a wireless network card, be sure to find out whether the wireless network card is compatible with your online TV.
Common TV support wireless network card chip model is RTL8191SU, RTL3070, RTL8712 driver-free, directly connected to the TV's USB port.
3, the wireless network signal strength is too low, that is, we often say that the signal is weak.
When your wireless network strength is less than 35%, although our machine can detect the network, it cannot be successfully connected. In order to ensure that the normal use of the wireless network requires the signal strength to be stable at more than 70% or more than two cells, the weak signal has the following conditions.
Countermeasures: Select a router with high signal strength according to the needs of home use.
4, can detect the signal but the connection fails.
When there is a wireless connection and a signal can be searched, but the connection fails, you need to check whether the encryption type, WEP length, and WEP mode settings are correct. Many models of Internet TV do not support advanced WPA encryption. The router's wireless network security options must be set to open system (open or open system), and allow wireless broadcasts, bands, and modes (rates) to be set to a fixed value. MAC binding, turn off the firewall, do not select "Auto Select" for all options. After the settings are successfully saved, restart the router. If necessary, check whether the settings take effect successfully. In addition, after restarting the router, restart the TV and re-search for the network connection.
Wireless router security settings:
1) WEP encryption is used. The settings are as follows: Select Open for authentication, select 64 Bit for WEP encryption, select ASCII for key, set one key, and set 5 digits for password.
2) WPA encryption is used. The settings are as follows: TKIP is selected for the password type, and PSK is selected for PSK/EAP. The password must be set to 8 bits.
Second, the network is unstable, good or bad, can be identified, but unstable
1, the wireless router itself cooling reasons The temperature rises, the vast majority of wireless routers will appear heat problems, the router's cooling function is not good, resulting in the chip overheating, will affect the work performance of the network card, wonderful will be dropped or even stuck.
The wireless router unstable solution in this case:
a. For a wireless router with good thermal performance.
b. Cool the wireless router, add a fan or place it in a relatively cool place.
2, the network where the router is poisoned Now the network virus is becoming more and more rampant. Once poisoned, it will continuously exhaust our limited network resources, causing the network to collapse. As long as the router is restarted, everything will return to normal.
In this case, we have to do the following two things:
a. Check your computer is not not poisoned, it is recommended to install an anti-virus software, upgrade to the latest, and then completely kill the virus.
b. Check the history of the access inside the router. Is it because the router is used by others? It is recommended that you improve the router settings and periodically change the password of the router to prevent other users from accessing the network. Install anti-virus software to protect the router
c. The router's DHCP pool is suspended. The computer in the LAN is disconnected intermittently and disconnected automatically. This situation is usually caused by a DHCP address pool being too small or an ARP attack.
The frequently dropped LAN solution is:
a. Increase the number of DHCP address pools, and buffer some addresses for the number of computers in the LAN to prevent the IP address of the computer from losing the IP after the IP address expires.
b. Perform ARP binding on the firewall of the computer to avoid frequent dropped calls due to ARP attacks.
3, peripheral equipment interference information is relatively large (like the frequency band signal, 2.4GHz frequency band RF remote control effect.)
Work in the 2.4G band, almost coincide with the wireless network card's frequency band, all have the possibility of mutual interference. If and just happens to interfere with the router's default 6-band, switching the band to 1 or 11 and 13 will work fine. Microwave ovens and cordless phones in the home also work in the 2.4G band, and they also interfere with wireless network cards. Microwave ovens work by using microwave generators to generate high-frequency vibration microwaves that can penetrate food and make foods. The water molecules in it also generate high-frequency, intense vibrations that generate large amounts of heat to heat the food. The international microwave frequency for heating and drying has four stages, which are segments, frequency from 890MHz to 940MHz; S segment, frequency from 2.4GHz to 2.5GHz; segment C, frequency from 5.725GHz to 5.875GHz; K segment, frequency It is 2.2GHz to 2.225GHz. The frequency range of household microwave ovens is L segment and S segment, among which S segment is mostly. We can look at the back of the microwave oven, most of them will find this type of words "Rated microwave frequency: 2450MHz." This frequency is exactly the same as the IEEE 802.11b/g operating frequency of 2.4 GHz, and the power of household microwave ovens is much larger than that of WLAN products. Even if the shielding is better, the impact on the WLAN is huge.
Reduce the interference of wireless network card:
a. Use 802.11N frequency band, also 5G frequency band, cut away from 2.4G. The router channel is switched to the 11-band or 1, 13-band, anyway, instead of using the default 6-band b. Use a good HDMI cable to enhance shielding and reduce electromagnetic leakage.
c. PCB design, strict two-wire equal-length equal-impedance design, and other layers of large-area copper-clad ground shield.
d. When built-in USB wireless network card, try to strengthen shielding and reduce the chance of interference.
e. When using an external USB wireless network card, try to use an extension cord to keep the card away from the HD player.
f. External NIC antenna Do not put the antenna on the HDMI cable and away from the HDMI cable.
Third, with the router settings
How to set the wireless router Steps: First, connect the wireless router to the power supply, insert the cable into the WAN port, and then insert a lan port into the network cable with the computer. After these are ready, open the computer browser and enter http in the address bar. ://192.168.1.1 (If your home is using a telephone line to get online, you need to prepare a modem, which is commonly known as "cat"). Enter the corresponding account number and password. Generally, all new purchases are admin. Set home page.
Step 1: Go to the router's settings homepage, click on the left "settings wizard" and then click to enter (usually automatically pop up)
Step 2: Pop up a setup wizard page and click "Next".
The third step: Now enter the Internet settings page, you can see there are three choices of Internet access, pay attention to if your home is to use the phone line dial-up Internet access choose PPPoE (ADSL virtual dial) dynamic IP general computer directly plug in The network can be used, and the upper layer has a DHCP server. Static IP is usually what the private line, it may be the bandwidth of the cell, the upper layer does not have a DHCP server, or want to fix the IP. Xiao Bian uses the more common dial-up method as an example to set up a wireless router, and then clicks “Nextâ€.
Step 4: Select PPPOE dial-up Internet access, you will need to fill in the Internet account and password, fill in the account number you provided when you opened the broadband provider, and then click “Nextâ€.
Step 5: This step is to enter the wireless settings, we can see the channel, mode, security options, SSID and so on, the general SSID is a name, you can easily fill in, then the mode is mostly 11bgn. Wireless security options we want Choose wpa-psk/wpa2-psk, so that it is safe to avoid cracking and hacking.
Step 6: The system will pop up a wizard prompt page for successful setup. Click “Complete†and the router will restart automatically. At this time, you are patient. The interface that appears after success.
Fourth, summary
If you find that the network connection is abnormal after the setting is successful, you can simply detect the following network where there is a problem by the following method.
1. Test signal strength. The ability to measure signal strength using a clientless connection tool checks the signal strength. If it is too weak, the wireless router may have quality problems.
2. Set up the channel. Set up a wireless router's working channel or add an external antenna to see if this enhances the signal.
3. Check the SSID configuration. Check if it is connected to your wireless network SSID. If not, switch back quickly.
4. Check whether the key you entered is incorrect. If the password is incorrect, the connection is not normal.
5. Update the whole software (system bug may cause WIFI instability, under normal circumstances does not consider WIFI module hardware is bad.)
