Hello all,

I've changed my Deco X50-4G router to a new Deco X50-5G router with an external antenna on the roof.

I want to benefit from my SIM 5G subscription from Vodafone Spain with improved speed.

I believe the network coverage is fine and mobile devices and hotspots have no issues in this area.

However, after installation the internet (LTE) connection is very unstable and drops every 1- 2 hour.

I selected network type "preferably 5G" but I see the router see constantly switching between 4G and 5G (and bands) till it drops.

See the picture the status when temporary connected with 5G.

TP Link technical support has no answer. They said it maybe the signal and it is a new product ;(

I have changed the network to fixed 4G and the connection is stable now.

Does anyone have an idea how to solve it?  Or is it faulty software?

Many thanks for your help
