@Suvajit Hi, you can install the beta firmware we provided on this thread to manually select the band, then confirm if the speed is better: https://community.tp-link.com/en/home/forum/topic/241534

@Manash When you chose band 40, did it show disconnect on the Status page? Can we have the screenshot? Any other details would be highly appreciated.

@RSBasera When you chose band 40, did it show disconnect on the Status page? Can we have the screenshot? Did you also try Jio and Airtel Sim card?

@JemyBoy I found you have a support ticket opened previously about the speed issue, which is TKID210302822, you can continue discussing the issue with the support engineers, I think they will be able...

@davidbrok1 I'm afraid not. The Onemesh routers cannot support to build a mesh network via an Ethernet/wired connection. We currently only have Deco support Ethernet backhaul. For more questions...

@Gaffer The support engineers was made aware of your issue. They will likely reach out to you via email to continue to troubleshoot your issue.
