Model: RE300
Hardware Version:
Firmware Version:

This Article Applies to:

Dual-band range extenders, such as RE200/RE220/RE300/RE450/RE650, etc.

 

 

Scenario/Phenomenon:

  • 5GHz frequency is not found when the extender scans for the host Network;
  • The range extender does not detect the router’s 5GHz Wi-Fi/5Ghz Hotspot Wi-Fi.

 

** If the range extender detects the 5GHz Wi-Fi of the host router but fail to connect to it / the 5GHz LED is off after set up, refer to this FAQ.

 

 

Troubleshooting suggestions:   

1.  Locate RE closer to main router during set up.

2. Confirm router's 5Ghz Wi-Fi is working fine and available on other wireless clients (laptop, mobile phones etc.).

* If  router's 2.4G & 5Ghz use the same SSID, please change a different SSID for 5Ghz to exclude the issue. 

3. Change a different 5GHz wireless channel on the main router:

If the main router’s 5GHz channel is set to Auto or between 149-165, change it to a channel between 36-48.

Here takes the TP-Link router as an example, go to Wireless Settings >> 5GHz >> select a recommended channel, such as 48, then save and reboot the router.

Note: The 5GHz wireless settings will vary on different manufacturer’s routers, please contact your router’s technical support for help.  

 

Notice for the (EU )Version TP-Link Range Extenders:

The range extenders with EU version, which can be verified by the device bottom sticker, only supports Band 1/2/3, they don’t support Band 4 channels on 5GHz  to comply with CE certification in Europe. If your host Wi-Fi is fixed on Band 4 channels, the TP-Link range extender will not see it.

V Band1: 36-48   (36,40,44,48)
V Band2: 52-64   (DFS) 
V Band3: 100-140 (DFS)
X Band4: 149-165 (149,153,158,161,165)

@Solla-topee Thanks... since I am eager to use Smart connect feature provided by TP link for seamless switching between bands for better speed, can TP link not provide a basic option of adjusting 5Ghz channel in the range of 36-48 while enabling smart connect? 

It doesn't make sense to hamper using this nice feature bcoz the user is using TP link's own extender..

Thank you for your feedback, for tp-link router with OneMesh/ Smart Connect feature, please check if below helps. 

- Login wifi router and  turn off 'Smart Connect' on router
