DRIVER INSTALLATION
Driver installation for Linux
1. Insert USB ash disk & WL-227N_ABAND NIC before booting
2. Boot Linux system and login
3. Create path [Wireless]: mkdir /etc/Wireless
4. Mount USB Hard Disk: mount /dev/sda1 /mnt
5. Copy tar le to Linux from USB Hard Disk:
cp /mnt/2008_0812_RT2880_iNIC_v1.1.8.0.tar.bz2 /etc/Wireless/
6. Decompress tar le to /etc/Wireless/, and it will generate a directory
[2008_0812_RT2880_iNIC_v1.1.8.0]:
tar -jxvf /etc/Wireless/2008_0812_RT2880_iNIC_v1.1.8.0.tar.bz2
7. Rename directory [2008_0812_RT2880_iNIC_v1.1.8.0] to [RT2880], in other
words, the driver’s path was /etc/Wireless/RT2880 (default path in Ralink
manual): mv 2008_0812_RT2880_iNIC_v1.1.8.0 RT2880
8. Now, we can complier driver (basic function):
a. Enter [RT2880] directory: cd RT2880
b. Rename [module-1.1.8.0] to [module]: mv module-1.1.8.0 module
c. Enter [/etc/Wireless/RT2880/module] directory: cd module
d. Complier driver: make
After make, it will generate ve les:
Module.sysmvers
rt2880_iNIC.ko
rt2880_iNIC.mod.c
rt2880_iNIC.mod.o
rt2880_iNIC.o
e. Copy iNIC_sta.bin and iNIC_sta_dat to [/etc/Wireless/RT2880/] from
[/etc/Wireless/RT2880/rmware/]:
• Enter [/etc/Wireless/RT2880/rmware/]: cd rmware
• Copy iNIC_sta.bin and iNIC_sta_dat to [/etc/Wireless/RT2880/] from
[/etc/Wireless/RT2880/rmware/]: cp iNIC_sta.* ../../

DRIVER INSTALLATION
9. Setup and bootstrap WL-227N_ABAND NIC:
a. Setup WL-227N_ABAND NIC:
insmod /etc/Wireless/RT2880/module/rt2880_iNIC.ko mode=sta
• If it shows “ra0:Ralink iNIC at 0xe0cc0000(hardware address),
00:43:0c:00:00:00 (MAC address), IRQ169 (IRQ address)”, the NIC is
boot strap successfully.
b. Bootstrap NIC parameters:
• IP address: ifcong ra0 inet 192.168.0.11 up
• If it shows the message as below, it is bootstrap successfully:
Send STARTUP to RT2880
close Firmware le
RACFG_CMD_BOOT_STARTUP
Update MAC(0)=00:11:22:33:44:55
Or, type [ifcong ra0] conguration. If it shows the message as below,
it is bootstrap successfully, too:
ra0 Link encap:Ethernet HWaddr 00:11:22:33:44:55

Interrupt:169
c. Setup NIC connect function:
Setup NIC frequency band: iwpriv ra0 set WirelessMode=9
Setup NIC connect target of AP: iwpriv ra0 set SSID=dlink
type [iwcong ra0] conguration. If it shows the message as below,
it is connect successfully:

SAFETY INFORMATION
Federal Communication Commission Interference Statement
This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and,
if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by turning
the equipment off and on, the user is encouraged to try to correct the interference
by one of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which
the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
FCC Caution: Any changes or modications not expressly approved by the
party responsible for compliance could void the user’s authority to operate
this equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2)
this device must accept any interference received, including interference that may
cause undesired operation.
For products available in the USA/Canada market, only channel 1~11 can be operated. Selection of other channels is not possible.
This device and its antenna(s) must not be co-located or operation in conjunction
with any other antenna or transmitter.
This device is going to be operated in 5.15~5.25GHz frequency range, it is restricted in indoor environment only.
IMPORTANT NOTE: This module is intended for OEM integrator. The OEM
integrator is still responsible for the FCC compliance requirement of the
end product, which integrates this module. 20cm minimum distance has to
be able to be maintained between the antenna and the users for the host
this module is integrated into. Under such conguration, the FCC radiation
exposure limits set forth for an population/uncontrolled environment can
be satised.

device complies with Part 15 of FCC rules. Operation is subject to the following
two conditions: (1) this device may not cause harmful interference and (2) this
device must accept any interference received, including interference that may
cause undesired operation.
LABEL OF THE END PRODUCT:
The final end product must be labeled in a visible area with the following "
Contains TX FCC ID: VUI-WL227N-5G ". If the size of the end product is larger
than 8x10cm, then the following FCC part 15.19 statement has to also be
available on the label: This device complies with Part 15 of FCC rules. Operation
is subject to the following two conditions: (1) this device may not cause harmful
interference and (2) this device must accept any interference received, including
