Link Quality is a measurement of receiving and transmitting performances over the radio. Network Address displays current MAC Address, IP Address, Subnet. and Gateway.
5.2.3 AVAILABLE NETWOEK SETTING Click Available Network tab and it will show all the available networks that the radio can reach. Select a proper SSID & BSSID you want to connect. Click the Refresh button to force and rescan the current available networks. Select one of SSIDs, and click Add to Profile to create a profile that can be configured with more wireless parameters. In this page, you can edit your profile name, configure wireless security like WEP, WPA, WPA2, 802.1x …etc.
5.2.5 WiFi Protected Setup An easy and secure setup solution for a WiFi network. You can choose a PIN Code or Push Button method to connect to an AP. ▓ Pin method: Step 1 : Press the “Pin Input Config (PIN)” button.
Step 3 : Enter the PIN code into your AP. Step 4 : Select the AP that you want to configure. Step 5: Wait for configuring your wireless AP to be the security setting.
▓ PBC method: Step 1 : Press “Push Button Config (PBC)” button Step 2 : Push the physical button on our AP or visual button on he WPS configuration page.
5.3 Virtual WiFi Setup Step 1 : Click “Virtual WiFi allowed” option to enable Virtual WiFi configuration / status page. Step 2 : Click “Start Virtual WiFI Soft AP” option to start Step 3 : Click “Config” button to configure Soft AP SSID and Security Key. Step 4 : Check “Setting Internet Connection Sharing” and “Auto Select Public Network” options to enable ICS. If setup up Shared Network manually, press “Apply” button to re-initialization ICS.
Add a Bluetooth Enabled Device To add a Bluetooth enabled device to your computer, you can use the Bluetooth icon located in the taskbar notification area or you can use a menu item in the Bluetooth Devices control panel. NOTE: Before a Bluetooth device can be found, it must be within range and set to be discoverable. To add a device using the Bluetooth icon: Click the Bluetooth icon, click Add a device, and follow the onscreen instructions. The Add a device wizard handles the pairing process.
Windows 10 Setting Use Bluetooth to facilitate wireless data transfers with other Bluetooth-enabled devices. Pairing with other Bluetooth-enabled devices You need to pair your Notebook PC with other Bluetooth-enabled devices to enable data transfers. To do this, use your touchpad as follows: 1. Launch the Charms bar. 2. Tap, then tap Change PC Settings. 3. Under PC Settings, select Devices then tap Add a Device to search for Bluetooth-enabled devices. 4. Select a device from the list.

You can enable the function by checking the icon of My Computer -> Control Panel -> Network -> file and printer sharing -> I want to be able to give others access to my files. Symptom : Slow or poor performance under AP mode Remedy : Try to select another channel for the communicating group or move your device closer to the Access Point.
8. Glossary IEEE 802.11 Standard The IEEE 802.11 Wireless LAN standards subcommittee, which is formulating a standard for the industry. Access Point An internet working device that seamlessly connects wired and wireless networks together. Ad Hoc An Ad Hoc wireless LAN is a group of personal computers, each with a WLAN adapter, connected as an independent wireless LAN. Ad Hoc wireless LAN is applicable at a departmental scale for a branch or SOHO operation.
systems, such as a LAN and a mainframe. In Internet terminology, a gateway is another name for a router. Generally a gateway is used as a funnel for all traffic to the Internet. IEEE Institute of Electrical and Electronics Engineers Infrastructure An integrated wireless and wired LAN is called an Infrastructure configuration. Infrastructure is applicable to enterprise scale for wireless access to central database, or wireless application for mobile workers.
uses the same IP address every time it reboots and logs on to the network, unless it is manually changed. Temporal Key Integrity Protocol (TKIP) The Temporal Key Integrity Protocol, pronounced tee-kip, is part of the IEEE 802.11i encryption standard for wireless LANs. TKIP is the next generation of WEP, the Wired Equivalency Protocol, which is used to secure 802.11 wireless LANs. TKIP provides per-packet key mixing, a message integrity check and a re-keying mechanism, thus fixing the flaws of WEP.
cracked in a couple of hours with off-the-shelf tools. Wireless LAN (WLAN) A wireless LAN does not use cable to transmit signals, but rather uses radio or infrared to transmit packets through the air. Radio Frequency (RF) and infrared are the commonly used types of wireless transmission. Most wireless LANs use spread spectrum technology.
mechanism, the transmitting station sends out an RTS packet to the receiving station, and waits for the receiving station to send back a CTS (Clear to Send) packet before sending the actual packet data. This setting is useful for networks with many clients. With many clients, and a high network load, there will be many more collisions. By lowering the RTS threshold, there may be fewer collisions, and performance should improve.
802.1x Authentication 802.1x is a framework for authenticated MAC-level access control, defines Extensible Authentication Protocol (EAP) over LANs (WAPOL). The standard encapsulates and leverages much of EAP, which was defined for dial-up authentication with Point-to-Point Protocol in RFC 2284. Beyond encapsulating EAP packets, the 802.1x standard also defines EAPOL messages that convey the shared key information critical for wireless security.
