My broadband modem shat itself so ISP sent me a new modem. I find my
internet speed is just shy of 100 Mbps.
ethtool says speed is 1000 Mbps. So I wonder did they send me a crippled
modem? The new modem is really dumbed down. If you go to 192.168.0.1
control panel, there is a lot less information than the old modem.

I don't have anything with regard to your question but I just want to say
that I am most impressed that you get a speed close to 100 Mbps. I assume
this means that you downloaded from some website at that speed. The highest I
ever got was around 6 Mbps. Which is fine for my needs and I don't even have
the fastest package my ISP offers but still , 100 Mbps is impressive.

ethtool is only relevant for the ethernet link between your NIC and the
next device, like a switch or a DSL modem. It doesn't say anything
about the link speeds behind the modem. Make sure that you have a link
of 1000MBit/s full duplex if both support it. Look what they advertise.

Surely ethtool shows you the speed you are talking to the modem, not the
speed that it (the modem) talks to the Internet?

As others already say, your speed is OK.

1000 means *if* your ISP allows (in future) you can push that through
it. If your ISP may be offers 1500 at some point, your modem will become
a bottleneck; stuck at 1000.

I would check your contract, what your ISP is supposed to deliver. If he
says 100 Mbps or 120, that's okay. But if it's 200 or more then there's
something wrong (or the web page you used to test wasn't the best choice).

What ethtool is telling you about is the speed negotiated between your
ethernet card and whatever your ethernet cable is jacked into. If you have a
gig switch and a gig NIC, you will have a gig connection between your computer
and the switch (and probably between that switch and anything else [on your
LAN] jacked into that switch that has gig NICs. What is happing on the
otherside of the broadband modem's router is not something ethtool knows
anything about.

Note: unless you are paying like $1000/month for full dedicated gig service,
you are getting "best effort" service. This means you *might* get gig service
if you are the *only* user on the 'net in your whole town (or city or
whatever). [Maybe in the wee hours of the morning.] Otherwise you and
everybody else is "sharing" a (few) gig.

Huh, no.

Here, we all get 1 gig bidirectional, actually 1 gig, measured, and not
shared. We have fiber to the home.

Actually, I have lowered the speed to save some money.

It is unlikely that your "fiber to the home" is dedicated 1gig, it is 1gig
"best effort". And yes, it will actually be 1 gig some of the time, possibly
much of the time, but during some times of the day, it will likely degrade to
something less, depending on how "busy" things are.

We have 1 Gbit/s guaranteed with FTH. For some rather little money we
can upgrade to 10 Gbit/s guaranteed.

Best effort contracts are long over. At least here in Switzerland and
AFIK in Europe as far as FTH is concerned.

I am not sure that is completely true.

My fibre gives me 40Gbps nominal, but I have been informed - perhaps
erroneously - that it is not a *time division*, but code division
multiplexed fibre, and is shared with other local users. So can suffer
from (some) contention.

That's BT Openreach in the UK

Any better information gladly accepted

The downstream is passively split, every router sharing your fibre sees
all the encrypted packets, but can only decrypt the ones intended for it
(and presumably a few "common" packets that all routers see?)

The amount you pay determines the maximum volume of packets you are
entitled to receive per unit time, there's a total of 2.5Gbps worth of
downlink and 1.25Gpbs of uplink.

if there are (up to) 30 users sharing your fibre, and everyone is
greedy, there's about 10Mbps per home available, but if someone is
paying for 900Mbps while the rest are just on 40 or 80Mbps, does he get
10x or 20x as much downstream as everyone else?

The uplink is rigid time division, so your router doesn't shine its
light on top of your neighbours

That's why I *always* get my 10.whatever Mbps

Well, strictly speaking it's the ONT that converts the router's 1Gb
ethernet to and from the fibre, which is doing the shining.

TX and RX can both happen at the same time, as they use different
wavelengths of light.
