I don¹t know that they have a lot of motivation to support ³legacy² access
points. The home brew guys tend to magically ³find² ways to install
software on these POS CPE AP/Router combos, which I don¹t think is a
coincidence. The linksys types of the world want to sell more routers, not
make routers that suddenly have an amazing 8 year shelf life. Most people
get tired of that POS box that gives them internet not working, and buy a
new LESS POS with whatever 802.xxx of the week/month/year/shopping season.
The margins probably really suck if you support a piece of plastic longer
than __ months, so I doubt you¹ll see anyone supporting their cheap box
any time soon. I bet if you offered them a way to do it for free, they¹d
look at it ;)

Why want to swing such a big hammer.  Even blocking those 2 IP's will
isolate your users, and fill your support queue's.

Set up a DNS server locally to reply to those IP's  Your customers
stay up
and running and blissfully unaware.

Log the IP's hitting your DNS servers on those IP and have your support
reach out to them in a controlled way, or  reply to any request via DNS
with an internal host that has a web page explaining what is broken
and how
they can fix it avoiding  at least some of the calls to your helpdesk.

Two words: "DNS Changer".  What did we learn from that?

My thoughts exactly.  Some walled gardens set up in those instances.

And don't blindly follow someone's advice without looking at impacts to
your
networks.  

CPE devices are just a huge cesspool.  Any device that already doesn't
let you
change username 'admin' is off to a bad start.   We have to get these
supposedly
'plug it in and never touch it' devices to be better at firmware upgrades.
