Hello, as you can tell, these stats are pretty shit. Yesterday, an electrician came and offered to connect a cable from the phone box in our building directly to the router to bypass all wires inside the walls and because the current wires are like 15 years old, so it makes sense that this would certainly speed up the internet.
He did it, the cable was about 3 building stories long and looked like this: https://imgur.com/a/ZE76K

It seems basic, it only had 3 wires inside without shielding and he only used 2, but I'n pretty sure that the current cable in the building are similar. Anyways, at first, the internet sped up to 3 mbps and ping decreased by 9ms, but then it went back to the stats above. Before, line attenuation was 34 db, now it increased for some reason...

Any help is appreciated.

Sorry but you are "polishing a turd" You have a poor connection, the work by the electrician was probably pointless. Sorry.
