Troubleshooting and Help A Q. What is WEP? WEP is Wired Equivalent Privacy, a data privacy mechanism based on a 40-bit shared-key algorithm, as described in the IEEE 802.11 standard. Q. What is a MAC Address? The Media Access Control (MAC) address is a unique number assigned by the manufacturer to any Ethernet networking device, such as a network adapter, that allows the network to identify it at the hardware level. For all practical purposes, this number is usually permanent. Unlike IP addresses, which can change every time a computer logs on to the network, the MAC address of a device stays the same, making it a valuable identifier for the network. Q. How do I avoid interference? Using multiple access points on the same channel and in close proximity to one another will generate interference. When employing multiple access points, make sure to operate each one on a different channel (frequency). Q. How do I reset the access point? Press the Reset button on the back of the access point for about ten seconds. This resets the unit to its default settings. Q. How do I resolve issues with signal loss? There is no way to know the exact range of your wireless network without testing. Every obstacle placed between an access point and wireless computer will create signal loss. Leaded glass, metal, concrete floors, water, and walls will inhibit the signal and reduce range. Start with your access point and your wireless computer in the same room and move it away in small increments to determine the maximum range in your environment. You may also try using different channels, as this may eliminate interference affecting only one channel. Also, open the access point's web-based utility, click Wireless > Advanced Wireless, and make sure the output power is set to 100%. Q. Does the access point function as a firewall? No. The access point is only a bridge from wired Ethernet to wireless clients. Q. I have excellent signal strength, but I cannot see my network. Wireless security, such as WEP or WPA, is probably enabled on the access point, but not on your wireless adapter (or vice versa). Verify that the same wireless security settings are being used on all devices in your wireless network. WAP4410N Wireless-N Access Point with Power Over Internet 71
