Constant outages

im an oldschool IT nut, i can tell you off the top of my head what device is what on my network just by seeing the MAC (first 3 sets are manufacturer of radio), and what IP i have assigned to it, as long as its not IPV6 (for the moment), ive been doing this "computer thing" since 82 when i wrote my mother's business programme at 12, and still know AT commands to get my Amiga to null modem over a serial con to my other systems since im not bothering to setup the TCPIP stack on it at the moment. so, im not the kinda person you tell "turn it off and on again", im the person that has said that many times. but it is next to impossible to get COX to acknowledge some users that understand which end they are speaking from. im already aware of buyouts and rebranding of companies, and how many network hardware manufactures have made their routers such grandma bait trash like linksys (...sorry... Linksys branded Belkin/Cisco) hydra6.
this (currently in use)modem however is BRANDED/BADGE as a "Motorola". and the model number is on the approved list of DOCSIS3.1 modems even if it has fewer uplink channels COX doesn't use, as is the Netgear, which is in my opinion better, but now i have to test it as it appears that new Netgear modem is no longer functional or got shorted out during line maintenance. it was working before the service call.
i have purchased ALL new hardware and cabling/testers since this 4 month issue of mine has been going on, to rule out slightly aged equipment. if COX would allow instant re-provisioning with known hardware on the account, it would be easier to drop the netgear back into service or at least test it on the flaky incoming service.
Cox apparently trusted arris since the phone service at my old business had a large clunky arris VOIP system that barely worked enough requiring out alarm system to be switched to cellular to avoid the many 3AM calls from the monitoring company. i can go on about my love/hate of Cox's service, but for me, the past 4 months has been utter TRASH.
TL;DR, i know my ...stuff...
