I can make sure the router I buy can run openwrt or ddwrt, but it
would be handy to know if I need to buy two or whether the current
one can at least do the job at one end of the diagram.

So you're saying that a router can run as a switch. This is presumably
by just ignoring the WAN port and using just the LANs?¹ And what does
buying a WAP do that the wireless on the router can't cope with?

I don't have any visitors and I don't know what I'd do in a DMZ.

I haven't got a DMZ or a "high security area". When I mentioned
security,  it was because I don't want to run WEP/None security
on the wireless instead of the current WPS2/AES. For who knows
what reason, using any sort of bridging/repeating functionality
in the router necessitated reducing the wireless to WEP. Perhaps
the router has 16 bytes of memory and it can't do too many things
at once.

Um, look, there's one house, one wife, small budget, and the current
box count is already at two.

Let's just imagine there's a wireless-proof gauze screen between the
two halves of the house. One router in each half is up to the task
of covering its half but no more. At the moment, one half of the
house (ironically the side with the modem) has next to no coverage.

¹ ie what's outlined in this one
