Advanced Configuration
How to open the browser-based utility
To access some advanced settings, you need to open the browser-based utility. Make sure you are
connected to the router, open a web browser and enter http://myrouter.local in a web browser or go
to 192.168.1.1.
The router will prompt you for a password.
If you changed the password during setup, enter the new password. Click LOGIN. If you didn’t change
the password, or skipped setup altogether, the default password is ‘‘admin’’.

8
Basic Router Settings
This screen allows you to change the router’s basic configuration.

9
Language
Select your language—To change language, select one from the drop-down menu. The language of
the browser-based utility will change within five seconds.

10
Internet Setup
The Internet Setup section configures the router to your internet connection. This information can be
provided by your Internet Service Provider (ISP).
Internet Connection Type—Select the type of internet connection your ISP provides from the drop-
down menu.
•Automatic Configuration – DHCP (default)
Keep the default only if your ISP supports DHCP or if you connect using a dynamic IP address.
(This option usually applies to cable connections.)
•Static IP
Select if you are required to use a fixed IP address to connect to the internet.
•PPPoE
Select if you have a DSL connection and your ISP uses Point-to-Point Protocol over Ethernet
(PPPoE).
•PPTP
Point-to-Point Tunneling Protocol (PPTP) is a service that generally applies to connections in
Europe. If your PPTP connection supports DHCP or a dynamic IP address, select Obtain an IP
Address Automatically. If you are required to use a fixed IP address to connect to the internet,
select Specify an IP Address and configure the options that appear.

11
•L2TP
Layer 2 Tunneling Protocol (L2TP) is a service that generally applies to connections in Israel.
Note—Connect on Demand or Keep Alive are options when choosing PPPoE, PPTP and L2TP.
They let you choose whether the router connects to the internet only as needed (useful if your
ISP charges for connect time), or if the router should always be connected. Select the
appropriate option.
•Bridge Mode
Bridge Mode disables all router capabilities and turns the router into an access point. The
router will cease to act as a DHCP server and its built-in firewall as well as the NAT features
will no longer be in effect.
•Wireless Bridge
A wireless bridge wirelessly connects to your main router and can share the internet
connection with devices connected to the bridge’s Ethernet ports.

12
Basic Wi-Fi Settings
5GHz Network Mode-----Select the wireless standards your network will support.

•Wireless-A Only
Select if you have only Wireless-A devices.
•Wireless-N Only
Select if you have only Wireless-N devices.
•Disabled
Select if you have no Wireless-A, Wireless-N, Wireless-AC and Wireless-AX (5 GHz) devices in
your network. 5GHz radio will be off after you choose this option.
Note—If you are not sure which mode to select, keep the default, Mixed.

13
2.4GHz Network Mode-----Select the wireless standards your network will support.
•Mixed (default)
Keep the default if you have Wireless-B, Wireless-G, Wireless-N 2.4GHz devices in your
network.
•Wireless-B/G Only
Select if you have Wireless-B, Wireless-G devices in your network.
•Wireless-B Only
Select if you have only Wireless-B devices.
•Wireless-G Only
Select if you have only Wireless-G devices.
•Wireless-N Only
Select if you have only Wireless-N 2.4G devices.

network. 2.4GHz radio will be off after you choose this option.
Note—If you are not sure which mode to select, keep the default, Mixed.
Network Name (SSID)
The Service Set Identifier (SSID) is a name used by devices to connect to a wireless network. SSIDs
are case-sensitive and must not exceed 32 characters. The default SSIDs for the 2.4 GHz and 5 GHz
networks are LinksysXXXXX and LinksysXXXXX_5GHz, respectively. The Xs represent the last five
digits of the router’s serial number, which can be found on the bottom of the router. If you changed
the SSID, both bands have the new SSIDs. You may give them different names through the browser-
based utility.
Note—If you restore the router’s factory default settings (by pressing the Reset button or
using the Configuration > Administration > Device Reset screen), the Network Name will
return to its default value. Change the Network Name back to its original name, or you will
have to reconnect all devices on your wireless network to the new network name.
Channel Width
Keep the default, Auto (20 MHz or 40 MHz) for best performance in a 2.4 GHz network using
Wireless-B, Wireless-G and Wireless-N (2.4 GHz) devices. For a channel width of 20 MHz, select 20
MHz only. For the best performance in a 5 GHz network, keep the default Auto (20, 40 or 80 MHz).
Channel
Select the channel from the drop-down list. Keep the default, Auto, if you are not sure which channel
to select.

14
SSID Broadcast
Keep the default, Enabled, to broadcast the router’s SSID. When wireless clients survey the local area
for wireless networks to associate with they will detect the SSID broadcast by the router. Attempting
to hide your Wi-Fi name does not make your Wi-Fi more secure. Anyone truly interested in accessing
your network can find it even if you turn off this feature. If you still do not want to broadcast the
router’s SSID, select Disabled.

15
Wireless Security
The router offers the following wireless security options:
WPA2/WPA3 Mixed Personal, WAP2 Personal, WPA2 Enterprise, WPA3 Personal, WPA3 Enterprise
(WPA stands for Wi-Fi Protected Access.)
WPA3 is the strongest security option.
Security Option Settings
WPA2 Personal
If you select WPA2 Personal, each device in your wireless network MUST use WPA2 Personal and the
same passphrase.
If you are not sure whether a device supports WPA2 or WPA3 Personal, select WPA2/WPA3 Mixed
Personal option in Security Mode.
Passphrase-----Enter a passphrase of 8-63 characters. This is the Wi-Fi password that provides
access to the network. It can be the same as entered in setup.
Disabled
If you choose to disable wireless security, you will be informed that wireless security is disabled when
you first attempt to access the internet. You will be given the option to enable wireless security, or
confirm that you understand the risks but still wish to proceed without wireless security.

help). Install the router again.
•If you have another computer, use that computer to install the router.

17
Your Internet cable is not plugged in message
If you get a “Your Internet cable is not plugged in” message when trying to set up your router:
•Make sure that an ethernet or internet cable (or a cable like the one supplied with your router)
is securely connected to the yellow Internet port on the back of the router and to the
appropriate port on your modem. This port on the modem is usually labeled Ethernet.
•Make sure that your modem is connected to power and is turned on.
If your internet service is cable, verify that the cable
modem’s CABLE port is connected to the coaxial cable
provided by your ISP.
If your internet service is DSL, make
sure that the DSL phone line is
connected to the modem’s DSL port.

18
•If your computer was previously connected to your modem with a USB cable, disconnect the
USB cable.
•Install the router again.
Cannot access your router message
To access your router, you must be connected to your own network. If you currently have wireless
internet access, the problem may be that you have accidentally connected to a different wireless
network.
To fix the problem on Windows computers, do the following*:
1. On your Windows desktop, click on the wireless icon in the system tray. A list of available
networks will appear.
2. Click your own network name. Click Connect. In the example below, the computer was
connected to another wireless network named wraith_5GHz. The wireless network name of the
Linksys E series router, Damaged_Beez2.4 in this example, is shown selected.
3. If you are prompted to enter a network security key, type your password (security key) into the
network security key field. Click OK.
4. Your computer will connect to the network, and you should be able to access the router.
*Depending on your version of Windows, there could be some differences in wording or icons in these
steps.

19
To fix the problem on Mac computers, do the following:
1. In the menu bar across the top of the screen, click the Wi-Fi icon. A list of wireless networks will
appear.
2. In the example below, the computer was connected to another wireless network named
wraith_5GHz. The wireless network name of the Linksys E series router, Damaged_Beez2.4 in
this example, is shown selected.
3. Click the wireless network name of your Linksys E series router (Damaged_Beez2.4 in the
example).
4. Type your wireless network password (Security Key) into the Password field. Click OK.
After setup
The internet appears to be unavailable
If the internet has difficulty communicating with your router, the problem may appear as a “Cannot
find [internet address]” message in your web browser. If you know that the internet address is correct,
and if you’ve tried several valid internet addresses with the same result, the message could mean that
there’s a problem with your ISP or modem communicating with your router.
Try the following:
•Make sure that the network and power cables are securely connected.
•Make sure that the power outlet that your router is connected to has power.
•Reboot your router.
•Contact your ISP and ask about outages in your area.
The most common method of troubleshooting your router is to turn it off, then back on again. Your
router can then reload its custom settings, and other devices (such as the modem) will be able to
rediscover the router and communicate with it. This process is called rebooting.

20
To restart your router using the power cord, do the following:
1. Disconnect the power cord from the router and the modem.
2. Wait 10 seconds and reconnect the power cord to the modem. Make sure it has power.
3. Wait until the modem’s online indicator has stopped blinking (about two minutes). Reconnect
the power cord to the router.
4. Wait until the blue Power and Internet lights on the front of the router are solid. This takes about
two minutes. Then, connect to internet from a computer.
