Advanced Dual-Band N Router
Linksys E2500 Chapter 1: Advanced Configuration
Beacon Interval A beacon is a packet broadcast by the
Router to synchronize the wireless network. Enter a value
between 20 and 1000 milliseconds. The Beacon Interval
value indicates the frequency interval of the beacon. The
default value is 100.
DTIM Interval This value, between 3 and 255, indicates
the interval of the Delivery Traffic Indication Message
(DTIM). A DTIM field is a countdown field informing
clients of the next window for listening to broadcast
and multicast messages. When the Router has buffered
broadcast or multicast messages for associated clients, it
sends the next DTIM with a DTIM Interval value. Its clients
hear the beacons and awaken to receive the broadcast
and multicast messages. The default value is 3.
Fragmentation Threshold This value specifies the
maximum size for a packet before data is fragmented
into multiple packets. If you experience a high packet
error rate, you may slightly increase the Fragmentation
Threshold. Setting the Fragmentation Threshold too low
may result in poor network performance. Only minor
reduction of the default value is recommended. In most
cases, it should remain at its default value of 2346.
RTS Threshold Should you encounter inconsistent data
flow, only minor reduction of the default value, 2347, is
recommended. If a network packet is smaller than the
preset RTS threshold size, the RTS/CTS mechanism will
not be enabled. The Router sends Request to Send (RTS)
frames to a particular receiving station and negotiates
the sending of a data frame. After receiving an RTS, the
wireless station responds with a Clear to Send (CTS) frame
to acknowledge the right to begin transmission. The RTS
Threshold value should remain at its default value of 2347.

filter out various types of unwanted traffic on the Router’s
local network.

SPI Firewall Protection To use firewall protection,
keep the default selection, Enabled. To turn off firewall
protection, select Disabled.
Internet Filters
Filter Anonymous Internet Requests This feature
makes it more difficult for outside users to work their
way into your network. This option is enabled by default.
Disable it to allow anonymous Internet requests
.
Filter Multicast Multicasting allows for multiple
transmissions to specific recipients at the same time. If
multicasting is permitted, then the Router will allow IP
multicast packets to be forwarded to the appropriate
computers. Select this option to enable the filter. This
option is disabled by default.
Filter Internet NAT Redirection This feature is used to
prevent a local computer from using a URL or Internet
address to access the local server. Select this option to
enable the filter. This option is disabled by default.
Filter IDENT (Port 113) The Filter IDENT (Identification)
option keeps port 113 from being scanned by devices
outside of your local network. This option is enabled by
default. Disable it to allow port 113 to be scanned.
Web Filters
Proxy Use of WAN proxy servers may compromise the
Gateway’s security. Denying Proxy will disable access to
any WAN proxy servers. Select this option to enable proxy
filtering. Deselect the feature to allow proxy access.
