Do you have the anitvirus option active?  If so please let us know what the logs indicate.  Also in the future this particular community is focused on US customers.  Global customers can get more localized help from the community at community.tp-link.com/en or if in mexico their regionally specific community at community.tp-link.com/mx

Your Deco M5 has HomeCare and that service has a built in Antivirus feature, that includes intrusion prevenetion and blocking of sites that my have or are being detected of having a comprimise.  That is what i was asking about.  As for support, you are working with a support agent however TP-Link Support is regionally based and you are currently on the US based community which services US customers.  We can at times provide best effort support to customers outside of our region but it is always best for you to talk to the team that supports your region.  That is why in my previous post i suggested you post on the community who handles  Spain, again that address is community.tp-link.com/en.    You can also reach out dirrectly to spain support at https://www.tp-link.com/es/support/contact-technical-support/
