11
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 browserbased utility.
Note—If you restore the router’s factory default settings (by pressing the Reset button or
using the Administration > Factory Defaults 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 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.
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.
12
Wireless Security
The router offers the following wireless security options:
WPA2/WPA Mixed Mode, WPA2 Personal and WEP. (WPA stands for Wi-Fi Protected Access. WEP stands for Wireless Equivalent Privacy).

• 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.
• 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 E8400 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.

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.
To reboot 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 flashing green LED between the Reset button and power port is solid. Wait two minutes before trying to connect to the Internet from a computer.
