Most network devices such as APs, wireless routers, switches, and hubs are usually connected to a network backbone using Ethernet Ethernet is a network protocol for data transmission over LAN.. In enterprise networks, APs normally connect to a switch with an Ethernet uplink and at homes, an AP normally connects to an ISP Internet Service Provider. An ISP is an organization that provides services for accessing and using the Internet. modem or a small switch using Ethernet. Though Ethernet is the most common and widespread uplink used for APs, some remote networks in particular have certain special uplink requirements. The following are some of the factors that require the need for an alternative to the standard Ethernet uplink of APs:
- Redundancy—In remote deployments, organizations have limited or no IT support and require the network to be always up to ensure productivity. Such organizations often require a backup link when the primary uplink fails. Some examples of organizations that require uplink redundancy include:
- Energy companies having unmanned remote sites that have to be remotely accessible for monitoring purposes.
- Healthcare and retail companies having remote and satellite offices that are required to be always up and accessible to carry out business.
- Organizations with remote offices where employees depend heavily on centralized or cloud based services.
- Lack of Ethernet uplink—Sometimes, extending an Ethernet uplink to a location is expensive or impossible due to geographical factors. In such situations, organizations require alternative uplink capabilities to connect to the internet and corporate resources. Some examples where an alternate uplink is required include:
- Remote site where wired broadband services such as DSL Digital Subscriber Line. The DSL technology allows the transmission of digital data over telephone lines. A DSL modem is a device used for connecting a computer or router to a telephone line that offers connectivity to the Internet. and ADSL are expensive or unavailable.
- Road warriors who need an AP to connect multiple devices but have limited or no access to Ethernet uplinks.
- Mall Kiosks, mobile clinics, first response camps, and other emergency camps during catastrophic disasters.
To configure 802.1X 802.1X is an IEEE standard for port-based network access control designed to enhance 802.11 WLAN security. 802.1X provides an authentication framework that allows a user to be authenticated by a central authority. authentication on uplink ports of an AP, complete the following steps in the WebUI:

- Select TPM Trusted Platform Module. TPM is an international standard for a secure cryptoprocessor, which is a dedicated microcontroller designed to secure hardware by integrating cryptographic keys into devices. in Certificate Type to configure a factory-installed TPM certificate for 802.1X authentication.
- Select User in Certificate Type to configure the user installed certificate for 802.1X authentication.
- If authentication type is selected, enter the user credentials in the and text box.
- Check the box to enable or disable server certificate verification by the AP.
