Hello there. 

I got a deco BE68 at the tail end of last year. It worked fine for the first bit of time, lets say 3 months. But recently I've been having constant problems. It will drop connection at least once a week, and even after rebooting it still does not allow me to connect to the internet on my devices. I verified that the cable its connected to is working fine as when i plug my laptop in it will give me good speeds on my speed test. When I plug it into my deco, the light at the bottom will turn green, however there is no connection when i connect my phone via wifi or my pc via ethernet. When I try to dos a speedtest on the deco app, it fails almost instantly. When i try to use ookla on my phone, it either says unstable connection or no connection at all. This has been one of the most frustrating experiences I've had with routers and is seriously making me question this brand in general. Can I please get some help here.

Im using Myrepublic 10gbps network.

i see that there is a user having similar problems as well 
I've tried the usual DNS swap and resetting the network numerous times 

Other user with similar issues

The only solution ive found is to swap the decos around and switch the main deco to a diff one and magically it will fix itself but die the next week
