Internet/Phone not working after touching ETP.

So out of curiosity of upgrading our home phone lines, I took a look at our ETP that's outside the garage. Took it out and put it back in. Didnt dismantle it, or cut any wires or whatever, but after that the internet speed dropped to 1mbps (originally 8~9 mbps). We had this speed about 4 years ago, and after installing a master splitter/filter, the increased drastically. I am not entirely sure why the speed dropped back after looking at it, perhaps faulty or loose wires. So I decided to reconnect the wires(exactly the way it was before), bought new gel 2way/3way wire connectors, and reconnected it.

Now both phone and internet is faulty. Both of it doesnt seem to work. The master filter we had was a really old one that only has blue/white and orange/white.

I ve been reading the forums a lot on installing a new master splitter, and it seems like the colour code was incorrectly installed from the first place. I ve bought a new master filter (orange/white, green/white, blue/white) and tried installing it, but our home wires seems to be slightly different from the ones that was mentioned online for people who has had a similar problem.

Our ETP currently has 4 cables, 3 black, and 1 white.

1st Black cable is rolled up and not used,

2nd black cable consists pf 3 wires inside (yellow, brown ish, white),

3rd black cable consists of 4 wires (Red,black,blue,white) Found the red/black rolled up and not used.

White cable consists of 6 wires (red,blue,green,black,white,orange)

So originally the technician installed the filter wiring like this:

The Blue/White wires from the splitter was joined to the Blue/white wires to the 3rd black cable mentioned. (Blue-Blue), (white-White).

[I read from posts that the Orange/white is connected to the line and not the blue/white, but this was how it was originally connected.]

The orange wire from the splitter was connected to the white wire from the White cable.

The White wire from the splitter was connected 3 way with the red wire from the white cable and to the yellow wire from the 2nd Black cable.

Blue -> Blue

White -> White

Orange -> White

White -> Red/Yellow to 2 different cable.

From reading different posts, I know some of the wiring contradicts how people connects the filter, I don't understand why it was working fine for years before I pulled it out for inspection.

What my actual plan was to install a 3 way master splitter (green/white -> cat5e) and installing a CAT5e cable going into the garage so I can place my router there with cat5e wired straight to the router, rather than going through the phone lines as different phone jacks seems to give different speed.

If someone could help me with this matter it'd be great.

Thanks
