Common faults of WLAN and its solution

In the development of Wired Network (hereinafter referred to as LAN) in the ascendant, wireless local area network (hereinafter referred to as WLAN) with the technology gradually mature and product costs continue to reduce, unknowingly has crept into our work and life.

The widespread spread of WLAN and broadband also makes related failures happen, so let's take a look at common wireless LAN failures.

Symptom: Unable to login wireless router for setup

Analysis and Solution:

Most of the hardware failures are joint loosening, network cable broken, hub damage and computer system failure, and so on. It is generally possible to use the observation LEDs to help locate. In addition, the voltage is not normal, the temperature is too high, lightning, etc. also easy to cause trouble.

Approach One: Check the router above the data signal indicators, power lights intermittent flashing for normal, such as abnormal first check access to the broadband line, you can switch to different network cable plug well. Check the network connection in the computer, reset the IP address, and if the IP address is not successful automatically, set the IP manually and disable the network firewall feature used by the system. (Computer science)

Option two: In the System IE connection settings Select "Never Dial Connection", click "OK" to end. Clear all options after entering LAN settings. Then open IE enter the router address to connect.

Method Three: The router to restore factory settings, reinstall the driver and login account and password.

If the solution is still unresolved please contact the vendor and check the hardware for conflicting issues.

Symptom: Can on MSN but can't open web page

Analysis and Solution:

A router is an address translation device that prevents both sides from connecting directly to the Internet when you or someone who communicates with you is behind a firewall or router. The network address translation devices used by both parties are required to support UPnP technology. About the router's support for this technology, please look at the router instructions you use, and consult the manufacturer's technical support.

One option: Individual routers need to set UPnP to "Enable" in LAN settings.

Option two: It could be caused by a virus. You can open Explorer to view resource consumption and CPU usage, if the occupancy rate is very high, it is likely to be infected with the virus, the anti-virus software to kill it.

Method Three: IE file damage. Download new IE for installation or repair with the operating system.

Symptom: Networking time is intermittent

Analysis and Solution:

A typical wireless router can provide three or more connections of more than three ways, most wireless routers will be set by default to "on-demand connection, when there is access to data automatically to connect" that is, every once in a certain time it will detect whether the line no-load, once connected and no data interaction, will automatically disconnect.

Approach One: Enter the wireless router settings interface, in the connection mode out of the choice of "automatic connection, in the boot and disconnect after automatic connection" can be.

Approach two: Check the network for network virus attacks, most likely an ARP network attack. Enter the network card properties, manually set the IP, replace the new IP address, if continue to drop the line, please use professional anti-attack software for defense.

Symptom: Network speed is too slow

Analysis and Solution:

The first may be the busy Web server, followed by a faint wireless signal.

One way: If the Web server is busy, it is not what our users can solve, you can try again after a period of time.

Method Two: In the Enterprise and Soho family uses the wireless local area network, the wireless router position placement often is neglected by the people. Improper placement of wireless routers is a direct cause of weak signals. The solution is simple:

First, placed in a relatively high position;

Second, placing and receiving end should not be separated more cement walls.

Third, as far as possible in the use of the central location of the end.

Symptom: status displayed as a packet can be sent, but no data accepted

Analysis and Solution:

First make sure your physical connection is correct. Log on to the router. Ping the access provider's DNS address with a router. If you can ping, the router to the Internet connection is unblocked, otherwise please check the configuration of the router. Then, using any PC in the internal network to ping the gateway (that is, the router's internal interface address), if you can ping, then the internal network connection is unblocked, otherwise, check the router configuration and PC configuration is correct and whether it is consistent. If the above two steps can ping, but still not on the network, then follow the steps to troubleshoot.

1, check the internal PC's gateway and DNS configuration is correct, and determine the next step after the error.

2, check the router's NAT settings to see if the configuration is OK. If the router configuration does not check for errors, it is a good idea to look at the NAT address translation table (not sure if your router supports this feature). See if the address translation for the internal network has a corresponding entry. If there is no proof that your NAT configuration must be wrong. then correct it.
