That clarifies the situation.I have used a clarity faceplate before.
Not all FTTC ISPs provide a free router, its often an option.
What is your ISP still Plusnet as on your profile page?
I have just seen your post on the plusnet forum http://community.plus.net/forum/index.php/topic,1024...
and you have a netgear router on the way
I still think openreach will prefer (or will have) to put the modem at the master socket.
They might convert the other hardwired broadband socket to a master and install the modem there, you can then use the patch cable and mount the supplied wireless (N ?) router where your existing access point is located.
I would wait to see what openreach install, then see if you require your additional AP.
but answering your question yes, no problem.
Your cable router would have to have an IP address in the same range as the OR supplied one (maybe 192.168.1.250 if the OR is 192.168.1.254)
check the DHCP range on the OR router and make sure it cannot hand out 192.168.1.250
also, as you said, DHCP off on your new router.
