Hello everyone
This problem is related to the 5Ghz channel on Airtel router.
Tp-link Range Extenders (EU) version supports : Band1/2/3 on 5Ghz to accord with the results of the CE certification as listed below:
RE (EU) version 5Ghz Band :
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);
So Airtel router's 5Ghz Wi-Fi channel should on Band 1/2/3 or RE(EU) will not able to detect its 5Ghz. Here are some suggestions for this issue:
1. Please contact Airtel support check what is current 5Ghz channel on Airtel router.
2. Change Airtel router Wi-Fi channel to Band1 Channel 36/40/44/48 if possible.
(Band 1 is recommended as Band1 is more stable compared with Band2/3 )
3. Try several reboots on Airtel router until router reverts to a Band 1-3 channel.
If the issue persists, please start a new thread here with the information below to look into the concern the further.
1- model and hardware version & country version (EU/ US/ UK etc.)of your device
2- model of router
3- photo of router's 5Ghz wireless settings

Hello, may I have the model number of the Airtel modem? When you try to connect to its 5GHz on the extender, how many signal bars can you see? Please check and ensure the 5GHz signal is good enough to keep a connection.

Same issue with me. RE200 is able to detect the 2.4G network of Airtel provided Huawei router but unable to detect 5G SSID. The router model number is HG8145V5.

@ManojNair - Thanks for your reply. I tried the manual option as well. However, it doesn't work for me in that mode as well.

Hi,
Thank you very much for your patience.
During the setup, the 5Ghz Wi-Fi of HG8145V5 could not be detected by RE200, right?
How about other 5Ghz networks, can they be detected by HG8145V5？
Please also try to change the wireless advanced settings on the HG8145V5, such as channel 40 and channel width 40mhz for 5ghz?
Can I have a picture of the bottom label on the HG8145V5?
By the way, have you tried to set up via WPS button?
Thank you very much.

Good day.
Sorry for the delay.
How about the speed from the 2.4ghz on RE305? is the 2.4ghz working well?
Did you have any wired devices and could you please also test the Ethernet speed from RE200?
If the computer is connected to the Airtel Wi-Fi at the same place, what is the 5ghz download speed and how about the link speed as well?
By the way, how far away from the RE305 to the Airtel modem?
Thank you very much.

Thanks for your response. I can see other 5G networks from the neighbourhood. I tried WPS option but nothing seems to be working for me. As suggested by you, I tried changing Channel Width to 40 MHz. However, the Channel is uneditable & it's in Auto mode. Please find the attached details of the router.
