Frequently Asked Questions - Linksys BEFSR81 User Manual

17. The Diag LED stays lit continuously.
The Diag LED lights up when the device is first powered up. Meantime, the
system will boot up itself and check for proper operation. After finishing the
checking procedure, the LED turns off to show that the system is working fine.
If the LED remains lit after one minute, the device is not working properly. Try
to flash the firmware by assigning a static IP address to the computer, and then
upgrade the firmware. Try using the following settings, IP Address:
192.168.1.50 and Subnet Mask: 255.255.255.0.
18. When I enter a URL or IP address, I get a time-out error or am prompted to retry.
A. Make sure that the other PCs work. If they do, ensure that your worksta-
tion's IP settings are correct (IP Address, Subnet Mask, Default Gateway,
and DNS). Restart the computer that is having a problem.
B. If the PCs are configured correctly, but still not working, check the Router.
Ensure that it is connected and ON. Connect to it and check its settings. (If
you cannot connect to it, check the LAN and power connections.)
C. If the Router is configured correctly, check your Internet connection
(DSL/cable modem, etc.) to see if it is working correctly. You can remove
the Router to verify a direct connection.
D. Manually configure the TCP/IP with a DNS address provided by your ISP.
E. Make sure that your browser is set to connect directly and that any dial-up
is disabled. For Internet Explorer, click on Tools, choose Internet Options,
and then the select the Connection tab. Make sure that the Internet Explorer
is set to Never dial a connection. For Netscape Navigator, click Edit,
Preferences, Advanced, and Proxy. Make sure that Netscape Navigator is
set to Direct connection to the Internet.
19. The Full/Col LED keeps flickering continuously.
A. Check the Category 5 Ethernet cable and its RJ-45 connectors.
B. There may be interference with other network devices. Try removing other
PCs or network devices to see if the problem persists. Eliminate each net-
work device one at a time to determine the cause.

Frequently Asked Questions

I'm an AOL member and I need more information. Additional information can be
found at AOL Keyword: Linksys Setup.
What is MIB? MIB (Management Information Base) is a data file that works in
conjunction with third-party SNMP software in managing the Router. To use
MIB files in conjunction with third-party SNMP software, follow the instruc-
tions that come with the third-party SNMP software. MIB data files are available
on the Linksys website, www.linksys.com.
What is QoS? "QoS" is Quality of Service. QoS is used to maximize a network's
performance according to its requirements. QoS ensures better service to high-
priority types of network traffic, which may involve demanding, real-time appli-
cations, such as videoconferencing.
What is SNMP? SNMP (Simple Network Management Protocol) is a widely used
network monitoring and control protocol. For more information on SNMP, see
"Appendix G: SNMP Functions."
What is the maximum number of IP addresses that the Router will support? The
Router will support up to 253 IP addresses.
Is IPSec Pass-Through supported by the Router? Yes, it is a built-in feature that the
Router automatically enables.
Where is the Router installed on the network? In a typical environment, the Router
is installed between the cable/DSL modem and the LAN. Plug the Router into
the cable/DSL modem's Ethernet port.
Does the Router support IPX or AppleTalk? No. TCP/IP is the only protocol standard
for the Internet and has become the global standard for communications. IPX, a
NetWare communications protocol used only to route messages from one node
to another, and AppleTalk, a communications protocol used on Apple and
Macintosh networks, can be used for LAN to LAN connections, but those pro-
tocols cannot connect from WAN to LAN.
Does the WAN connection of the Router support 100 Mbps Ethernet? Because of the
speed limitations of broadband Internet connections, the Router's current hard-
ware design supports 10 Mbps Ethernet on its WAN port. It does, of course, sup-
port 100 Mbps over the auto-sensing Fast Ethernet 10/100 switch on the LAN
side of the Router.
