Hi,

My Deco M4 sudently not broadcasting the 5ghz wifi, its only work with the 2,4ghz. I all ready turn on both band signal in the deco apps 2.4 an 5ghz but it only broadcasting the 2.4ghz. If I use the 5ghz only there is no wifi signal at all if i check from my phone, laptop, or computer. And if i turn on the 2.4ghz only mode, it works just fine...I think the 5ghz band is broken. I try to reset it a view times but the result still the same...Please see the photo...if all deco work as mesh, only the broken M4 thats not using 5ghz band as a backhaul....only 2.4ghz...

How/Where can i fix this?

Hi, Thank you very much for the feedback.

May I know how long you have had the Deco M4?

I think it is very likely the Wi-Fi module of this satellite Deco is broken and you might need to contact the local support to ask for warranty service.

Thanks for the reply.

I don't think the local warranty service provides repair service but you could make a call for comfirmation.

You could try to refer to this link to run a firmware recovery and reflash the current 1.6.2 version to see whether it made any difference:

How to use firmware recovery if the Deco become brick ---HTTP Uboot method

Thank you again and Best regards.

Hi David, i allready did at the begining reflashing the firmware to the latest firmware via method 2 from "How to use firmware recovery if the Deco become brick" didnt make any difference, I pretty sure that the chip for 5ghz is broken...so its hardware issue i guess...
