I'm not even sure such a thing exists but it feels as if it ought to.
I want a 'WiFi switch' that I can plug into an existing LAN such that it allows WiFi access on the *same* subnet. Thus it won't do anything clever like DHCP or DNS or anything as that will be done by existing devices on the LAN.
All the 'range extenders' I can find are WiFi both in and out and also tend to create their own subnet. Anyway I need something that hangs on a hard-wired ethernet connection.
Is there such a thing?
Much to my surprise it was simpler to do than I expected. I have a 3G router here and it does what I want if I just configure it with a static IP and *not* as a DHCP server. I've plugged one of its ethernet LAN ports into the local 192.168.13.0 subnet and it does exactly what I want, the other ethernet LAN ports are just more ports on the 192.168.13.0 (as you'd expect) but so is the WiFi from it and when you connect using the WiFi the DHCP server on the 192.168.13.0 provides what's needed.
There's not a functional SIM in the 3G router so it *can't* connect that way!
