Troubleshooting / FAQs

If mobile users do not have roaming access to the SMC2655W access point:

Make sure that all the SMC2655Ws and stations in the ESS in which the WLAN mobile users can roam are configured to the same WEP setting, SSID, and authentication algorithm.

If you forgot your password or your SMC2655W has locked up, you can reset it to factory defaults by performing the following steps:

1)Locate the [Default] button on the back of the SMC2655W Access Point.

2)Unplug the power from the back of the AP for 10 seconds.

3)Depress the [Default] button for 3 seconds.

4)Plug the power connector into the AP while depressing the [Default] button.

5)Release the [Default] button after 3 seconds. Wait 3 seconds and then depress the [Default] button again.

6)The "LNK/ACT" and "TX/RX" LEDs will blink once per second about 10-12 times. Release the [Default] button when these LEDs begin flashing rapidly.

What is a Wireless LAN?

A local area network that transmits over the air typically in an unlicensed frequency such as the 2.4GHz band. A wireless LAN does not require lining up devices for line of sight transmission like IrDA. Wireless access points (base stations) are connected to an Ethernet hub or server and transmit a radio frequency over an area of several hundred to a thousand feet which can penetrate walls and other non-metal barriers. Roaming users can be handed off from one access point to another like a cellular phone system. Laptops use wireless network cards that plug into an existing PCMCIA slot or that are self contained on PC cards, while stand-alone desktops and servers use plug-in cards (ISA, PCI, etc.).

What is AD-HOC?

An AD-HOC network is a peer to peer network where all the nodes are wireless clients. As an example, two PC’s with wireless adapters can communicate with each other as long as they are within range. A wireless extension point can extend the range of an AD-HOC network.

What is the 802.11 standard?

A family of IEEE standards for wireless LANs first introduced in 1997. 802.11 provides 1 or 2 Mbps transmission in the 2.4GHz band using either a frequency hopping modulation (FHSS) technique or direct sequence spread spectrum (DSSS), which is also known as CDMA. The 802.11b standard defines an 11 Mbps data rate in the
