We have Charter -- with a plan that "guarantees" 18Mbps down and often far exceeds it, but still offers only 4Mbps up and usually exceeds it by just a smidgen. I see Charter advertising only 66Mbps down and 4Mbps up for their "Business" service. How do you have a 100Mbps download service with Charter, and what is your upload speed?

(Our son's Internet service in VK3 is 100Mbps up *and* down.)

As was mentioned earlier, the speed varies with load.  I've seen 103
Mbps downloads in the wee hours. I've also had problems viewing
streaming video from the Wx Channel in the evening and that is no where
near the 103 Mbps.  I have a subscription to a great weather service
(Weather Tap), which was really nice for storm chasing with NEXRAD RADAR
as near as possible to real time displays. (it takes several minutes to
build the images from multiple returns so "real time" is not possible)
but in the last year, the load had increased at various nodes to the
point of that service becoming useless.  Use tracert (service name or
IP) to see all the hops the signal takes and the time at each hop from
you to the service.

For example open the command prompt window and simply type in "tracert
ARRL.com" (without the quotes) Leave a space after tracert.   I get 16
hops with 3 timed out. It starts with "Tracing route to arrl.com
[] over a maximum of 30 hops". Most are less than 25 ms,
but there were also 25, 24, and 27 ms hops.  Do this at 7:00 PM and
again before you go to bed unless that is around 9:00.  Try to do this
every 3 or 4 hours around the clock, mid week and week ends.  You should
see some major differences between between the time when kids get home
from school, prime time, late hours and early morning. As was said
before, there will be bottlenecks somewhere.  It can be your service,
IP, or some other node, or nodes.

When I first went to the 100Mbs it was great, but it also shares the
same cable with all the other subscribers of many speeds and many are
now opting for the 100 Mbs service with no download limit.  I have never
seen providers with Gbps offerings.  Gbps = Giga bits per second, or
1000 Mbps  (1 Gbps = 1000 Megabytes per second)

Please note the lower case b (Mbs) means bits while the upper case B
(MBs) means bytes.  These are often displayed as (Mbps) and (MBps). One
byte = 8 bits.
