In this scenario, we will be using a working Linksys EA9500 Max-Stream™ AC5400 Tri-Band Wi-Fi Router and Linksys RE7000 Max-Stream™ AC1900+ Wi-Fi Range Extender in the network. The wireless settings must be the same on both the router and extender.
Make sure that the Linksys EA9500 has the latest firmware. There is no need to enable Seamless Roaming since this feature is already part of the firmware.
Write down the wireless network names (SSIDs) for both bands.
NOTE: You can name both radio bands the same wireless name or provide a different name for each band. To know how to check or change the wireless settings of your Linksys EA9500, click here.
Write down the wireless password and make sure the Security mode is either WPA2 Personal or WPA2/WPA Mixed Mode. Also take note of the setting for Channel width (Auto is recommended).
If any changes were made to the router, click Apply then Ok to save the settings.
Seamless Roaming is also part of the Linksys RE7000 firmware.
Open a browser to log in to the web-based setup page of your range extender. For instructions, click here.
Under Wireless, click Basic Settings.
On the Basic Settings page, make the following changes:
b. 5 GHz Extended Wireless Settings
ii. Password - Give it the same wireless password as your router’s 5 GHz band. This is case sensitive.
iii. Channel Width - Must be the same as the router’s 5 GHz band (Auto is recommended).
iv. Security Mode - Must be the same as the router’s 5 GHz band.
