Wireless network fails, the network administrator will always make trouble. There are some general investigation of failure is relatively easy, but some not so easy. Here are some of the wireless network problems on the schedule to do
Investigation work to see specifically how to operate it?
Wireless router for wireless Internet access, it has become progressively popular. However, wireless Internet access, we often encounter a wide range of wireless network failure, network failure which seriously affected the normal
Internet efficiency. In fact, we strengthen the investigation as long as usual, summed up a variety of common wireless network trouble-shooting experience, I believe in the future we can become experts in a managed wireless network!
Investigation and connecting lines to address the closing of not only wireless network failure
View wireless network connection status information, we sometimes see the wireless network can begin to send information, but can not receive information from the outside, this way one-way communication will obviously affect our normal operation of the wireless access
. When the unfortunate encounter one-way wireless network communications problems, we can follow the thinking of each of the following investigation:
First, the wireless network connection to ensure smooth lines in the state. In the view line is in connection state, we can first open the IE browser and the pop-up browser window address bar to use the router default
IP address (the address from the router generally able to find the operating instructions), then enter the router login name correctly, open the router admin interface. Then, run the ping command to management interface to
ping about the local Internet service provider's DNS server address, if the destination address can be ping-pass, then it would show that the router device to the Internet service provider in the flow line connection between the state, to
Is the destination address can not be ping-pass, then it shows some parameters within the router may not be set correctly, then we must be inside the router configuration parameters about each examination.
Internal configuration of the router in the confirmation of the premise parameters are correct, we can find a LAN network configuration is correct, the normal Internet workstations, and perform in the workstation ping command to ping what route to
Uses the IP address, if the address can be normal ping pass, then it means that the internal LAN connection also in a flow state line, if router ping the IP address of barrier, that we must have
To check the local workstation and the router using the network parameters are consistent with the network parameters, meaning that their parameters are in the same subnet address. If the above can be successfully ping each address through
However, only the wireless network connection is still in the state of not closing, that we could focus on the local workstation to check the DNS parameters and gateway parameter settings are correct in identifying these parameters correctly, we need
Re-enter to the router admin interface, find aspects of parameter settings NAT options, and check the option is configured correctly. Check the operation of the course of this argument, we focus on them to check the NAT
Address translation table is an internal network address translation entries, if not, would only fault of not closing the wireless network is mostly due to improper NAT configuration, and then we just will be the internal network address translation
Head right to the NAT address conversion table on it.
Troubleshoot connections, broken network address wireless network intermittent fault
In the local area network access to the Internet through a wireless router in the network case, if the LAN workstations can be normal while the Internet often, while the Internet can not fault the normal phenomenon, we
First need to ensure that the workstations and Internet access between your wireless router parameters must be correct, the basis should focus on examination of the wireless router connection is set properly. Typically, wireless routers
General to support three or more kinds of connections, but by default most wireless routers will use the "on-demand connections, where data is automatically connected to access" this connection, in other words, every
Certain period of time will automatically detect the wireless router equipment at this time whether there are empty lines, if successfully connected to the device does not detect a data exchange line in the move, it will state the wireless connection is connected
Access line automatically disconnected. For this reason, when we process the actual Internet, wireless networks often experience intermittent network failure breaking phenomenon, we can try to access to the wireless router admin settings interface, find the connected party
Type setting options, and see whether the parameters of the option has been set to "auto connect and disconnect the power automatically after the connection", if not correct, you must modify the connection over time, in the end
Admin interface save operation will save the previous successful modify operation parameters, and finally click the wireless router device restart I believe that this can solve most of the wireless network intermittently broken network failure.
Of course, by the above setting still does not solve the intermittent network failure breaking phenomenon, we need to examine the presence of local wireless LAN network virus attacks, because once the ARP network unlawful attack by viruses, then
, There may be intermittent broken network failure. At this point we may in the local workstation, open the Local Area Connection Properties settings window, then enter the property to the card interface device, in an attempt to modify the interface
IP address of the adapter and use, look at the new IP address condition, the intermittent fault is still there off network if the wireless network failures continue to occur, we must attack with a professional tool for anti-virus software
Pieces to protect the wireless LAN.
Investigation connected position, to solve wireless network problems slow Internet
When you try to wireless access, if you find a very slow access speed, we should conduct the investigation and two operations. First need to confirm that our current investigation and a visit is in the WEB server is busy working
For the state, once the target server is in a busy working state, then the only thing we can do is try to avoid the peak of the Internet. If at any time access to WEB server, the access speed has been very slow, then
Comparison of wireless transmission signals are mostly weak cause. Which led to relatively weak signal wireless transmission main reason is often the location of wireless router to connect devices placed properly. In order to maximize the wireless signal
Strength, we must bring the wireless router device placed in a position where relatively high, but also to ensure that the equipment and workstations can not have more concrete walls, otherwise it is easy wireless signal transmission
From outside interference, resulting in a huge range of signal attenuation, which affects the speed wireless Internet access. In addition, the need to remind you that, if the wireless router device is used for local area network, then we must ensure that
The device is located in the center of all workstations, each workstation can ensure the fast transfer of data.
Troubleshoot the connection status, address can not log on the wireless network failure
First, you need to declare that here the reference to "can not log failure" mainly refers to the wireless router can not log into the admin interface, resulting in a wireless router can not log on for many reasons, we should
Connection status from the wireless router set to see the device at this time whether there is hardware failure. Under normal circumstances, we can observe the wireless router control panel lights to quickly determine the device
The existence of the wireless network hardware failure. For example, if the wireless router, the power lights are not bright, it is likely that the device input voltage is not normal, this time we have to re-replacement of a new
Wireless router device. If the power is always in long bright lights, then the state, which is not a natural phenomenon, then we might as well check the equipment connected to the broadband line, you might consider switching to other networks
Lines reconnect.
Confirm the status of the wireless router under normal circumstances, we may enter into the LAN workstation system, look at the current network connection used to see the workstation using the IP address is static or dynamic address
State address, if previously used a dynamic address, we can try to modify the workstation to use a static IP address IP address, while the local system's network firewall closed off. Through the above efforts,
If we still can not log on the wireless router, you can try to modify what IE settings. Modify IE settings, you can first open the IE browser window, and the implementation of the window menu bar "Tools" /
"Internet Options" command, the Internet option in the pop-up window, click the "Connection" tab, and in the corresponding tab page will be "Never dial a connection" selected. The label after one click
Page in the "LAN Settings" button, and then all options will be set all the empty pages, and finally click "OK" button to end the IE settings for operation. After completion of the above setting operation, and then try to browse IE
Browser address box, enter the address of the router to connect, maybe this way we can successfully log into the wireless router.
If the above can not solve the problem of the investigation, then the wireless router, we can restore the Control Panel button in the parameters of all the equipment back to factory settings, then re-set, I believe that most of
Can not log on to solve the fault of the wireless network.
