Ends up helping technically illiterate ESI through relatives. Some renovations screwed the internet connection.
Me: ah ok...
ESI: What are you doing?
Me: I go home to grab my old wireless router. You can keep it.
ESI: But the guy never told me about this.
Me: I am not sure but I think I have a solution. Never seen this before.
Comes back with router and wires.
ESI: But the guy told me that I only need a wire with few cms of length and said nothing about that router.
Me: This will do.
ESI: I don't want wires.
Me: Let's hide it in the box where they go.
Me: Lets plug in wires, configure the router and hope for the best.
Me: It works.
ESI: But how?
Me: Just good guessing.. I had to improvise the whole thing. I had no papers or documents.
ESI: Are you sure about this? I need to call someone.
Me: It is OK... I think.
Me: **shakes my own head while observes anxiety**
The hell that actual technical assistant have to through...
