ISP’s plan doubled in speeds, but speeds stayed the same !
I have a “real-time” speed-meter, so I can tell .
The old-plan was advertised as 100Mbps-down, and 5Mbps, up — ACTUAL speeds, maxed-out at 118Mbps-down, and 5.9Mbps-up .
The NEW-plan is advertised as 200-Mbps-down, and 10Mbps, up, but the ACTUAL speeds, remained the same .
I’m finding-out, that a max of 5.9Mbps MAY be insufficient, for my M1-Max Mac, as most of my data is in the cloud, and incremental “Time Machine” backups, are taking a VERY LONG TIME !
I wonder if you are using an older cable modem that is DOCSIS 3.0 and not 3.1, what is the make and model? Have you let the ISP know about what you are experiencing, sometimes they need to push an update to your modem or make a change on their end to allow more bandwidth to your endpoint.
It is an Docsys 3.1 Arris G34/AX3000 . It is supposedly compatible with my ISP . My ISP is aware of the model of modem, and the slow speeds .
Back in 1991, I worked for a software-company in Massachusetts, and they had a central “hub” / ‘patch-board”, distributing the internet, to all of the offices on that floor . I learned that it was advisable to have coax from the same spool-of-wire, so that all of the impedances would match .
Here in this neighborhood development, they only replace an underground segment with modern coax, when the segment fails, and there are SOME segments that are “1987”-“fine-nine” old TV-coax, which almost pre-dates, the modern Internet .
I’m wondering if there isn’t an “impedance-mismaach”, from the mix, of old, and new, cabling ?
You may very well need a tech from the cable company to come and test your line running from the street to the house. When testing the up/download speeds, it is always best to test from a wired connection.
