I set up a wireless router in my upstairs home office (providing good coverage for the second floor) and a second one downstairs in the living room where signal strength is too low to be useful. There are probably lots of different ways to do this but I would like feedback on the theoretical as well as practical pros and cons of two approaches:1) One wired network (192.168.0.0) connecting the LAN port of the DSL modem and the WAN ports of both wireless routers. Each router would give out their own small pool of DHCP addresses, 192.168.1.0 upstairs and 192.168.2.0 downstairs.
2) The wireless router upstairs would be the only one with DHCP enabled and would connect to the one downstairs via the LAN-side switch. In effect, this turns the downstairs router into a bridged access point.
Are both approaches equally valid?
