3.2. Uninstalling the MAC OS Driver
Please follow the below steps to uninstall the LM821 driver on a MAC host computer.
Step 1 :
Run the uninstall.command script in the same folder the driver is extracted.
Step 2 :
You would need the root password to uninstall the driver. Enter the password
when prompted in the terminal
Step 3 :
Once the password is provided the script will uninstall the driver.
Note :
Please DONOT delete the network interface (en2, en3 or similar) created in the network
preference because MAC does not recreate this interface when the driver installation is

4. Wireless LAN Basics
Wireless LAN network defined by IEEE 802.11b/g/n standard committee can be
configured in the following modes:
•Ad Hoc (Point-to-point) wireless LAN.
•Infrastructure wireless LAN.
Ad Hoc Wireless Network Infrastructure Wireless Network
Ad Hoc network is a group of PCs installed with wireless LAN cards, this group of PCs is
called a BSS (Basic Service Set). PCs in this group can use their wireless LAN cards to
communicate with each other, but cannot connect to the Internet.
The main difference between Infrastructure wireless networks and Ad Hoc wireless
networks is that the PCs in an Infrastructure wireless network can access the resource
in the Internet through an Access Point.
Depending on your application requirements, you can easily set up your PC’s network to
be an “Ad Hoc” or “Infrastructure” wireless network. Generally speaking, if your network
includes an Access Point, we recommend setting your network as an “Infrastructure”
network to allow connectivity to the Interne

5. IP Address
To use this WiFi module with a computing device, the host device must be equipped with
a USB interface. All drivers and supporting software for the module must be installed and
configured first.
Ask your system administrator for the following information, which might be needed
during the driver installation:
•Wireless Client Name
•Wireless SSID
•The host’s unique client and workgroup name
For your network account you will need the following:
•Username
•Password
•IP address
•Gateway address
•Subnet mask (if you’re not using a DHCP client)
Any computer on a network is identified by a unique IP address. There are two methods
to assign an IP address to a computer on a TCP/IP network:
•Static IP addressing
•Dynamic IP addressing (DHCP Client)
In networks with static IP addressing, the network administrator manually assigns an IP
address to each computer. Once a static IP address is assigned, a computer uses the
same IP address every time it reboots and logs onto the network. You may manually
change the IP address in the Network Properties dialog box. Networks using static IP
addresses is easy to set up and do not require additional network management software.
In networks with dynamic IP addressing, a DHCP server in the network dynamically
assigns IP addresses to all clients every time they log onto the network. Networks using
dynamic IP addresses require setting up and running a DHCP Server.
