Chapter3 Advanced Configuration •PPPoE: 492 •PPTP or L2TP: 460 Network Setup The Network Setup section changes the settings on the network connected to the Router’s Ethernet ports. Wireless Setup is performed through the Wireless tab. Router IP This presents both the Router’s IP Address and Subnet Mask as seen by your network. Router IP Address Network Address Server Settings (DHCP) The settings allow you to configure the Router’s Dynamic Host Configuration Protocol (DHCP) server function. The Router can be used as a DHCP server for your network. A DHCP server automatically assigns an IP address to each computer on your network. If you choose to enable the Router’s DHCP server option, make sure there is no other DHCP server on your network. Network Address Server Settings (DHCP) DHCP Server DHCP is enabled by factory default. If you already have a DHCP server on your network, or you don’t want a DHCP server, then select Dsable (no other DHCP features will be available). Startng IP Address Enter a value for the DHCP server to start with when issuing IP addresses. Because the Router’s default IP address is 192.168.1.1, the Starting IP Address must be 192.168.1.2 or greater, but smaller than 192.168.1.253. The default Starting IP Address is 92.68..00. Maxmum Number of DHCP Users Enter the maximum number of PCs that you want the DHCP server to assign IP addresses to. This number cannot be greater than 253. The default is 50. Clent Lease Tme The Client Lease Time is the amount of time a network user will be allowed connection to the Router with their current dynamic IP address. Enter the amount of time, in minutes, that the user will be “leased” this dynamic IP address. After the time is up, the user will be automatically assigned a new dynamic IP address. The default is 0 minutes, which means one day. Statc DNS (-3) The Domain Name System (DNS) is how the Internet translates domain or website names into Internet addresses or URLs. Your ISP will provide you with at least one DNS Server IP Address. If you wish to use another, enter that IP Address in one of these fields. You can enter up to three DNS Server IP Addresses here. The Router will use these for quicker access to functioning DNS servers. WINS The Windows Internet Naming Service (WINS) manages each PC’s interaction with the Internet. If you use a WINS server, enter that server’s IP Address here. Otherwise, leave this blank. Time Setting Select the time zone in which your network functions from this drop-down menu. (You can even automatically adjust for daylight saving time.) Time Setting Click Save Settngs to apply your changes, or click Cancel Changes to cancel your changes. Setup > DDNS The Router offers a Dynamic Domain Name System (DDNS) feature. DDNS lets you assign a fixed host and domain name to a dynamic Internet IP address. It is useful when you are hosting your own website, FTP server, or other server behind the Router. Before you can use this feature, you need to sign up for DDNS service with a DDNS service provider, www.dyndns.org or www.TZO.com. If you do not want to use this feature, keep the default setting, Dsable. DDNS The Router offers a Dynamic Domain Name System (DDNS) feature. DDNS lets you assign a fixed host and domain name to a dynamic Internet IP address. It is useful when you are hosting your own website, FTP server, or other server behind the Router.

FCC ID: Q87-WRT54GV81 Report No: SA960827L15 1 RF EXPOSURE REPORT REPORT NO.: SA960827L15 MODEL NO.: WRT54G ver. 8.1 ACCORDING: FCC Guidelines for Human Exposure IEEE C95.1 APPLICANT: Cisco-Linksys LLC ADDRESS: 121 Theory Drive Irvine, CA 92617 (USA) ISSUED BY: Advance Data Technology Corporation LAB ADDRESS: 47 14 th Lin, Chiapau Tsun, Linko, Taipei, Taiwan, R.O.C. TEST LOCATION: No. 19, Hwa Ya 2 nd Rd., Kueishan, Taoyuan, Taiwan, R.O.C. FCC ID: Q87-WRT54GV81 Report No: SA960827L15 2 RF EXPOSURE MEASUREMENT (MOBILE DEVICE) 1. INTRODUCTION In this document, we try to prove the safety of radiation harmfulness to the human body for our product. The limit for Maximum Permissible Exposure (MPE) specified in FCC 1.1310 is followed. The Gain of the antenna used in this product is measured in a Fully Anechoic Chamber (FAC) calibrated for antenna measurement in ADT, and also the maximum total power input to the antenna is measured. Through the Friis transmission formula and the maximum gain of the antenna, we can calculate the distance, away from the product, where the limit of MPE is reached. Although the Friis transmission formula is a far field assumption, the calculated result of that is an over-prediction for near field power density. We will take that as the worst case to specify the safety range. 2. RF EXPOSURE LIMIT According to FCC 1.1310: The criteria listed in the following table shall be used to evaluate the environmental impact of human exposure to radio-frequency (RF) radiation as specified in 1.1307(b) LIMITS FOR MAXIMUM PERMISSIBLE EXPOSURE (MPE) FREQUENCY RANGE (MHz) ELECTRIC FIELD STRENGTH (V/m) MAGNETIC FIELD STRENGTH (A/m) POWER DENSITY (mW/cm 2 ) AVERAGE TIME (minutes) (A)LIMITS FOR OCCUPATIONAL / CONTROL EXPOSURES 300-1500 ... ...

F/1500 30 1500-100,000 ... ... 1.0 30 F = Frequency in MHz FCC ID: Q87-WRT54GV81 Report No: SA960827L15 3 3. FRIIS FORMULA Friis transmission formula : Pd = (Pout*G) / (4*pi*r 2 ) where Pd = power density in mW/cm 2 Pout = output power to antenna in mW G = gain of antenna in linear scale Pi = 3.1416 R = distance between observation point and center of the radiator in cm If we know the maximum Gain of the antenna and the total power input to the antenna, through the calculation, we will know the MPE value at distance r. Ref.: David K. Cheng, Field and Wave Electromagnetics, Second Edition, Page 640, Eq. (11-133). 4. EUT OPERATING CONDITION The software provided by Manufacturer enabled the EUT to transmit and receive data at lowest, middle and highest channel individually. 5. CLASSIFICATION The antenna of this product, under normal use condition, is at least 20cm away from the body of the user. Warning statement to the user for keeping at least 20cm or more separation distance with the antenna should be included in users manual. So, this device is classified as Mobile Device.
