Hi @Diegomar ,

Thanks for troubleshooting that you have done.

Please log in the web management interface of the Router, go to Advanced > Wireless > Wireless Settings, change the wireless channel into another one.
For 2.4GHz wireless client devices, adjust 2.4GHz channel width into 20MHz, for 5G wireless client devices, adjust 5GHz channel width into 80MHz or 40MHz to avoid interference.
If the issue persists, please contact your local support with the result of the above troubleshooting steps and warranty consultation.

Hi joseph..!!

I changed the wifi channel and the problem persists. In fact, the computer and other devices that I have connected to the LAN also lose connection. Regarding calling local support, I wanted to clarify that I have had the router for several years (3) and it is not under warranty.I changed the wifi channel and the problem persists.

Hi  @Diegomar,

It seems that the router may have hardware problems, which may be caused by its aging. It may also be that there is interference in your current usage environment. Can you compare other routers in the same environment to see if there is the same situation? If not, then it is indeed a problem with the router. It is recommended that you consider buying a new router.

I find it strange that a router that has been used for 3 years starts to work badly. It seems like planned obsolescence. I will probably buy another router and it will probably not be from this brand. It is a shame because I liked this brand for its speed but I cannot go around changing routers every 3 years. Thank you.
