@Murtaza911 You can download firmware 1.2.0 which improve overall Deco performance. You can also check what's new in the firmware. https://community.tp-link.com/en/home/forum/topic/837036

@rs1975 Open Deco App go to Wi-Fi Settings and change the SSID and use same as your router and turn OFF Wi-Fi on your router.

@SayeemAhmed It's time to TP-LINK 😄

@ruben_calle No there is no problem with 80 MHz and the Main problem is your country is'nt allowed channels 36, 40, 44 and 48 and these channels can work easily on Apple devices and Android tablets...

@LuukJ There is a firmware 1.4.5 you can download from the link below and install directly from Web UI....

@LuukJ Have u tried factory reset and do the setup again? And are you facing this issue after firmware update?
