Should I put either of these devices back in the cable junction box outside my home? (alien.top)

For a while now I've had 1200/200 service with comcast and could only ever achieve 30 upload. I've inquired about this a couple times and comcast always said that the next gen service just wasn't available in my area yet. Well they performed some maintenace in the area recently and I was hopeful I would be able to get the nextgen service but I was still stuck at 30.

I'd always seen these things in the junction box but never paid them much attention. I always prefer to see if there's anything I can do to fix or improve things before calling a tech out so I decided to replace the ground block and remove whatever those other 2 devices are. Lo and behold, my modem now shows 5 upstream channels instead of 2 and I now get 100 upload.

One of the devices (orange band) is an SHP3-35 high pass filter. No idea what the green one is, there are no markings on it. Maybe an attenuator? Anyone know if I really need either of these? It seems one or the other was holding back my upstream channels.
