This all works fine, but when I "undock" the laptop to use it elsewhere, the ethernet port on the hub *stays enabled*. This means that:

a) the ethernet lights on the hub are blinking the whole time, but even worse

b) one by one all the other devices on my wired network get disconnected.

Can you elaborate on what you mean by the other devices on the network get disconnected?  Do they lose network connectivity and/or does your laptop lose access to them?  Does it affect both wireless and wired devices?

All the wired devices in the router's 'attached devices' list disappear.  They typically go away in groups, 2 or 3 at a time (but this is maybe because of the slow page refresh).  Not sure if the groups are related to being on the same ethernet switches.  The whole process usually takes just a few minutes before all the wired devices are gone (from the router's perspective).

Once they 'disappear', the devices are no longer pingable by numeric IP address, although this is admittedly from a laptop that's on the wireless network (The laptop still has internet connectivity when all this is happening and can access the router's stats web pages).  When I go and physically look at the affected devices, their ethernet ports appear to have 'signal' in that the LEDs are lit.  But no packets (at least, the tx/rx lights don't seem to blink IIRC).

I don't know off hand whether the wired devices still have connectivity (between themselves, or to the internet), since they are mainly things like NAS, printers or 'smart device' bridges.  I guess I should probably put another laptop on the wired part of the network and see if *it* can ping the NAS (It probably won't be able to access the internet via the router if the router doesn't believe it exists!).  From the non-blinking LEDs I'm guessing not, but haven't verified.
