Random Disconnects & slow speed occuring, again?

Old modem was tall & skinny, when new, no issues. Today's new modem is short & fat.
But like the old modem's issue this new one is reoccurring just like last.
Yes I wiggled & jiggled even disconnected and inspected my connections, all solid & clean.

Not a wire is looped, molded, folded or zip-tied "got to keep'm separated", as the old tune goes.

Of course I reboot & OEM reset many times, peripherals keep disconnecting, is it due to your party line?
Everyone's gone most to work, my speeds are WARP-fine, what a perk!
But alas, they're home & Net they roam, my speed dropped to 0.8 MB/second!!?

Don't blame my sides connections, it's your EXPEN$IVE Party Line (P.L.) that's frustrating the [Edited: Language] out of me.
BTW: I speed test & watch it go down, kinda like the Stock Market in near free-fall. Also when our TV drops signal I immediately WiFi my phone to speed test the modem, it's pathetically slow! (see pix below)
So...
All cheeky grins aside, business wise I understand the P.L. use, but come-on man, you're masking the issue with MB/s speed increases to cover your mistake is merely temporary. As this I.o.T. (Internet of Things) simply keeps growing AND Net users per-household increases, dedicate line us it like it used to be & everybody will be happy. AND don't con me into "pay more for higher speeds", that wasn't like that when we first contract signed on.
__I know what's going on, please fix it.
