Troubleshooting

This section addresses common issues you might encounter with your Linksys E900 router.

No Internet Connection

• Check Cables: Ensure all Ethernet cables are securely connected to the correct ports on the router and modem.
• Power Cycle: Perform a power cycle of both your modem and router (turn off, wait 30 seconds, turn on modem, wait for boot, turn on router).
• Modem Status: Check the indicator lights on your modem to ensure it has an active internet connection.
• Router Lights: Verify that the Internet light on your router is solid, indicating a connection to the modem.
• ISP Issue: Contact your Internet Service Provider (ISP) to confirm there are no service outages in your area.

Slow Wireless Speed or Dropped Connections

• Router Placement: Move the router to a more central location, away from obstructions and interference sources (cordless phones, microwaves, other Wi-Fi networks).
• Channel Interference: Access the router's web interface and try changing the wireless channel. Channels 1, 6, and 11 are generally recommended as non-overlapping channels.
• Disable WMM Support: Some users have reported improved speed and stability by disabling WMM (Wi-Fi Multimedia) support in the router's QoS settings. To do this, log into the router's web interface (192.168.1.1), navigate to "Applications & Gaming", then "QoS", and disable WMM Support. Save changes.
• Firmware Update: Ensure your router's firmware is up to date.

Cannot Access Router Setup Page (192.168.1.1)

• Wired Connection: Ensure your computer is connected directly to one of the router's LAN ports with an Ethernet cable.
• IP Address: Verify your computer is set to obtain an IP address automatically (DHCP).
• Browser Cache: Clear your web browser's cache and cookies, or try a different browser.
• Firewall/Antivirus: Temporarily disable any firewall or antivirus software on your computer that might be blocking access.
• Reset Router: If all else fails, perform a factory reset by pressing and holding the reset button on the back of the router for 10-15 seconds. Note: This will erase all custom settings, and you will need to reconfigure the router.
