Fed up with Netgear ANY router

> 2. Refuses to maintain assigned IP to devices.

   Generally, it's more helpful to describe actual actions/results,
rather than attribute an attitude to an inanimate device.  How, exactly,
does a router "refuse" to do anything?  Does it emit an error message
(some place) like "I refuse to do that!"?  "fail" and "refuse" are
spelled differently for a reason.

   Do you mean that devices with Address Reservations get some wrong
addresses?

> 4. Assigns duplicate IPs constantly.

   "constantly" or "repeatedly"?

   The most common reason for either of those DHCP problems is the
presence of another DHCP server on the LAN.  Firmware defects in Netgear
routers are common enough, but problems like those are seldom caused by
the router.

   For example, occasionally, some Internet-of-Junk gizmo with a
"hotspot" mode might leave its built-in DHCP server running after it's
been configured, and has joined your LAN.  A misconfigured Raspberry Pi
computer is another potential culprit.  As usual, many things are
possible.

   One test would be to disable the DHCP server in the RAX80, and see if
devices still manage to get IP parameters (from some other DHCP server).

> 1. Flaky all the time, losing connection to devices.

   Not a very detailed description of anything.  "connection" between
device and router?  "connection" between device and Internet?

> 3. NOT the speed I expected!

   That's fine for a rant, but not a useful description of anything.
The non-psychics in your audience might know very little about "the
speed [you] expected", or the speed you observed, or how you measured
it.

   Other basic useful info would include the router's firmware version,
and identification of what's connected to the router's WAN/Internet
port.
