Issues to be aware of when deploying wireless APs

Wireless AP (Access point), which is the wireless switch for wireless networks and the core of wireless networks. When deploying wireless APs, in order to prevent a variety of failures, users should master some basic considerations to ensure that wireless AP deployment is not a problem, this article from the practice summed up 10 points of attention, hoping to help you plan the deployment of wireless AP.

1, fill out the warranty card, safeguard their own rights and interests

When deploying wireless APs, you need to take the time to fill out the warranty information for the newly purchased wireless AP device. In particular, the new deployment of wireless AP equipment more necessary, can not rely on the previous experience, and one-sided view of wireless AP equipment quality are very clearance. In six months to a year, no one will be able to see any problems with these devices. Filling out warranty information is the only way to protect your future product maintenance rights.

2, on-demand to adjust the signal strength

Some wireless AP devices allow users to adjust to the signal strength through the network interface. Most users typically operate directly with the maximum signal strength, however, given the different requirements for wireless signal strength in different situations, such as in the car park may not need too strong wireless coverage intensity, therefore, we need to the wireless network coverage required for careful consideration, Then the actual signal strength is adjusted appropriately.

3. Provide standby power for wireless AP

The wireless network administrator needs to provide standby power (UPS device) support for all wireless APs. Only in this way can the wireless network remain normal when the main power supply fails.

This is a very important issue, first of all, to prevent accidents caused by major power failures. The second is to respond to the power supply in a sudden stop two seconds to start again. This is enough for a wireless connection to result in a network disconnect. Also, for a large number of users to connect to the wireless network of devices are battery-powered laptops or mobile devices, they are not affected by the temporary blackout phenomenon. As a result, most wireless devices set up the ability to automatically re-establish lost connections, and if the user is authenticated in the network settings, everyone will be blocked from back-end network resources before being authenticated. This causes confusing users to call countless help calls to inquire.

4, give full play to the wireless AP itself security features

At present, even for the low-end wireless AP, also equipped with a number of security features. This makes the vast majority of wireless APs allow administrators to use MAC addresses to restrict network access. Some wireless APs also provide an alert mechanism to send a warning message by e-mail when a user attempts to connect to the network repeatedly using an incorrect password. Therefore, in the actual deployment of wireless AP, the user is necessary for wireless AP devices to provide a comprehensive understanding of the security functions, so as to effectively through the equipment provided by the function of the network to optimize the reasonable.

5. Use a meaningful SSID

Many information technology experts recommend that you turn off the SSID broadcast for the wireless AP. However, for hackers, even the SSID is not broadcast, it is easy to find. To address this issue, it is recommended that the user use the SSID name that contains the specific meaning. The advantage of this is that users who first connect to the wireless network can clearly determine whether they are connected to the correct network.

6, the wireless connection as an unsafe mode of treatment

One of the great advantages of wireless networks is that users do not have to physically connect to the device to access the network. Therefore, encrypting the network is a necessary task. Here, it is recommended that users should adopt a more secure approach. Instead of simply trusting all users connected to a wireless network, the right thing to do is to see the wireless network as an Internet connection. Only users who have been authenticated by a VPN or similar mechanism can be allowed to access the entire network wirelessly.

7. Preventing overlapping of DHCP scopes

Once there was a case in which a company purchased a second wireless AP in order to increase the coverage of the wireless network to a wider context. At the same time, a technician with no actual work experience was told that the device was required to use the same settings as other access points. This results in the same DHCP scope configuration for both access points. Fortunately, the access point looks at IP address conflicts on the network before assigning IP leases. Otherwise, the immediate consequence is that overlapping DHCP scopes within coverage can cause a lot of trouble for end users to use.

8, reset the wireless AP initial password

Once the wireless AP is deployed, the first thing to do is to reset the internal password. Otherwise, anyone who uses the Internet to get the default password may have direct access to the configuration interface of the access point.

9, access equipment should try to choose the power supply mode of Ethernet

To ensure that wireless networks are covered as widely as possible, many companies prefer to deploy wireless APs at the top of the ceiling or similar locations. This causes the access point to be difficult to connect to the power supply problem. In this case, there are generally two solutions, one is to use the power extension cord, and the other is the way to power on the Ethernet (PoE). We recommend that you use the second option, which provides power to the access point via an unused Ethernet port. For network devices, connecting the end of the cable to a dedicated Poe module avoids the hassle of using a wire.

10, the deployment of wireless AP location do not close to metal objects

When deploying wireless APs, users need to be aware that the actual location of the deployment should not be subjected to radio interference. Once there was a case where the customer found that the wireless network was not working properly and consulted the relevant department, and after providing the location of the access point, the technician found that the user's access point device was located just under the metal roof of the steel beam at the top. Therefore, the surrounding metal has caused serious interference to the radio signal. After the final adjustment of the location of the access point, the existing problems are solved immediately. Therefore, we should try our best to avoid deploying the equipment in the vicinity of the metal structure when we deploy the wireless AP.
