  Hello @vpm 

In case phone automatically connects back to router Wi-Fi when set up RE (may lose RE set up page), try to turn off mobile data and forget router ' wifi on the phone temporarily How to remove existing wireless network profile on Android&iPhone

Open Tether app

Connect to RE's default SSID 'TPLINK Extender XX' and  set it up again on Tether app

 

If RE's 2.4Ghz& 5Ghz  Leds are still off, please examile wifi password again by reconnect to router wifi and put in wifi password, you could also  try some tips in guide here : [Troubleshooting]What should I do if Internet speed becomes slow via Range Extender?

  @Solla-topee Already did that . Still the phone wifi disconnects form tether app while setup. When I connect back immediately it shows the same thing(error message)

Because of this issue I used a ethernet cable from extender to do the setup. But still not working

Hello  @vpm 

thank you for the photo,  RE has not connected to router wifi yet. 

1- Please verify if correct 2.4Ghz Wi-Fi password  was put in:   Forget router Wi-Fi on your mobile phone and manually input the Wi-Fi password to verify the router’s Wi-Fi password is correct?  ( Phone Settings > Wi-Fi >tap router's Wi-Fi SSID to forget network or Long press Wi-Fi name to delete the Wi-Fi profile). 

 

2. Set up 855Re from Wireless page (for new UI)

. 

 

What is the model of wifi router, did you change any settings or update firmware for it? How long has the RE working with the same router? 

 How about the Led status on RE after set up? 

If still the same, please help collect the log after 3-5mins RE set up . If RE set up failed, wait for 3-5mins , go to Settings page, save the whole log file there. 

Please also check  router if has any advanced settings MAC Filtering, Access Control,etc.

Hi   @Solla-topee 

 

Wifi Router : Titanium 2122A Dualband 

https://www.amazon.in/Titanium-2122A-Dualband-Supports-1xVOICE/dp/B08B4X2HRB 

 

Yes the extender was working fine till yesterday 4 PM

 

all of a sudden the signal led turned off

 

When I tried to do quick setup again,  (even manually with the method you mentioned above) Signal led turns on for a second and turns off , and repeat.

 

1. Host network password is correct

2. I contacted the ISP and their person also inspected and made clear that there is no recent changes to the host modem , (Firmware , Mac filter ,...)

Here is the setup step by step

in second last screenshot, I tries both retry and start over several times.

 

Also 

1. I tried with the neighbors wifi modem (same model, single band) and same result

2. Tried connecting to phone hotspot , also same result

Hello  @vpm 

Please change a different 2.4Ghz Wi-Fi channel on the main router, channel among 1-11 should be fine.  

If router uses WPA3, try to change Wireless security type: WPA2-PSK (AES) 

 

If the same, can I know how long do you have this range extender? If it has been working fine with the same wifi router like 1-2 years, you could contact the retailer or local support to check warranty. 

If its relative new,   please share 1)  a photo of the router 2.4Ghz Wi-Fi settings   2) RE log after 3-5mins set up failed from Settings-> System tools> system Log 

For 'Signal led turns on for a second and turns off , and repeat.' Do you mean the Signal and  WiFi Leds turn on for a sec and goes off, and turn on again? Can you check router log or router client list and see if RE gets any IP address at that time
