Nice to see you again.

Were you trying to say the wireless coverage of the Deco X20-DSL is not powerful enough?

"it only operates well if I'm close to the box", can I have more details about what would happen if the clients are a little bit further away?

I see you mentioned there are 3*X20-DSL on different locations, is this the only one with problems?

Have you tried to factory reset this one or swap the location with the other two, then check whether it is always the same unit with issues?

Best regards.

Hi, sorry for the delay.

May I know the model number of your mobile phone? Can I have a screenshot of the error message?

Except for the smartphone, would other mobile devices have the same notification when they are a little bit far away from the X20-DSL?

Sometimes, the barriers in between will interfere with the wireless signal, and would the phone has the same notice when it is in the clear sight of Deco X20-DSL?

There are some suggestions for your reference:

1. Temporarily turn off the 2.4ghz on the main network.

2. Disable the "Mesh Technology" on the smartphone.

Best regards.
