The address range on my network is 192,168.2.2-192.168.2.254, gateway
192.168.2.1, subnet 255.255.255.0.
I have just purchased a pair of HDMI extenders (TX/RX) that I have
discovered are hard-coded to 192.168.0.0 addresses.
Is it possible to these devices to communicate to each other over my
network? At the present they are not.
Googling suggests that the answer might reside in changing the subnet
but I get lost as soon as they start attempting to explain binary
numbers and I haven't found any practical examples.
Many thanks for any help/advice.

These are 2 different networks and you need routing between them. You
need a professional router to do this, most home routers are crap and
aren't capable of running such a task.
In my opinion, these HDMI extenders are also crap and should be
forbidden, best thing is to get rid of them and buying some that
support IPv4 and IPv6 where you can set your address manually.

If only the extenders need to communicate to each other, it is easier,
they don't need to care about your subnet, you just need to tell them
the IP address of each other.

Thanks foryour guidance. At what point does a router become capable?

Do configuarable extenders exist? I have a pair that do work, by
adapting to my network by some means, they are not configurable, and
they don't have the facilities of the new ones.

Can't do that, can I? As I said the IP address is hard coded.

Looks as though I'll be sticking with the old ones and sending the new
ones back.

That would be best, also use the rating to tell other about that.
