View our Wireless Troubleshooting pages  if you are not seeing a FlashRouter wireless network or if you have trouble getting a good wireless signal.


Navigate to the Wireless > Basic Settings tab to view or change your wireless network names.

Single Band 2.4 GHz - Wireless-N

  • Wireless Mode: Access Point. This setting should not be changed unless you are setting up a wireless extender.
  • Wireless Network Mode: Mixed. N-Only will isolate the 2.4 GHz broadcast and may provide faster wireless speeds, but if you have legacy devices like printers, old gaming systems, or old computers you should set this to Auto. Setting this to Disabled will turn off your wireless broadcast entirely.
  • Wireless Network Name (SSID): FlashRouter24. Change the name of your 2.4 GHz wireless network here.
  • Wireless Channel: Auto. The router scans for interference from other devices and chooses the least crowded channel.
  • Channel Width: 20 MHz. The 40 MHz option is available on the 2.4 GHz network and may offer higher speeds in certain cases, but we do not recommended using this setting as it can issues with wireless connections on many legacy devices.
  • Wireless SSID Broadcast: Setting to Disable will hide the wireless SSID and force you to manually join the network.

Dual Band 5 GHz - Wireless-A (No AC)

  • Follow the 2.4 GHz band instructions above to make sure each band is correctly configured.

  • Wireless Mode: Access Point. This setting should not be changed unless you are setting up a wireless extender.
  • Wireless Network Mode: Mixed. Setting this to Disabled will turn off your wireless broadcast entirely.
  • Channel Width: Wide HT40 (20 + 20 MHz). Higher channel width provides better WiFi performance on the 5 GHz band.
  • Wireless Channel: Auto. The router scans for interference from other devices and chooses the least crowded channel.
    • If you are having trouble joining your 5 GHz network try setting a specific Wireless Channel.
  • Extension Channel: auto. If you feel you are not getting appropriate throughput, you may check specific extension channels for improvements.
  • Wireless Network Name (SSID): FlashRouter50. Change the name of your 5 GHz wireless network here.
  • Wireless SSID Broadcast: Setting to Disable will hide the wireless SSID and force you to manually join the network.

Dual Band 5 GHz Wireless-AC

  • Follow the 2.4 GHz band instructions above to make sure each band is correctly configured.
  • If you are using a Tri-Band router use this and the additional 5GHz instructions below.

  • Wireless Mode: Access Point. This setting should not be changed unless you are setting up a wireless extender.
  • Wireless Network Mode: AC/N-Mixed. Recommended for best wireless AC performance. Setting this to Disabled will turn off your wireless broadcast entirely.
  • Wireless Network Name (SSID): FlashRouter50. Change the name of your 5 GHz wireless network here.
  • Wireless Channel: Auto. The router scans for interference from other devices and chooses the least crowded channel.
    • If you are having trouble joining your wireless-AC network try setting a specific Wireless Channel.
  • Channel Width: VHT80 (80 MHz). Higher channel width can provide better WiFi performance on the 5 GHz band.
  • Extension Channel: upper upper. This extension channel usually provides the best overall speeds, but if you feel you are not getting appropriate throughput, you may try others to check for improvements.
  • Wireless SSID Broadcast: Setting to Disable will hide the wireless SSID and force you to manually join the network.

Tri Band 5 GHz Wireless-AC

  • Follow the Single Band 2.4 GHz and Dual Band 5GHz Wireless-AC instructions above to make sure each band is correctly configured.
  • You may notice the ordering of these three bands differs across router models.

    • If you are having trouble joining your wireless-AC network try setting a specific Wireless Channel.
  • Channel Width: VHT80 (80 MHz). Higher channel width can provide better WiFi performance on the 5 GHz band.
  • Extension Channel: lower lower. This extension channel usually provides the best overall speeds, but if you feel you are not getting appropriate throughput, you may try others to check for improvements.

Navigate to the Wireless > Wireless Security tab to view or change your wireless passwords.

Recommended Wireless Security Settings

  • Important: In order to secure your ALL Wireless networks use WPA 2 Personal / AES security settings. You must use this security mode and WPA algorithm for optimized wireless connections.
  • WPA Shared Key: Wireless#[then add the last 5 digits of your FlashRouter Order #]
    • e.g. Wireless#98765 for Order #100098765. This is set for all three wireless networks.
    • If your wireless password is not working make sure you did not forget to include the Wireless with a capital 'W' and the # sign before the last 5 digits of your order number. 
    • You can change your wireless password here at any time, must be at least 8 characters long.
    • Passwords can be the same or different for all three networks depending on what you prefer.

Note that not all devices are compatible with Dual Band networks, join the 2.4 GHz network if your 5 GHz network is not available.

Click Apply Settings to save any changes you make. You may need to rejoin the wireless network after certain changes.
