I want to connect my device that only have a rj45 port for wired ethernet. I have several wireless routers at hand, from several manufacturers (dlink, TPlink, etc)
My plan was to connect the device using: wired device -> wireless router ethernet port -> wireless router wireless interface -> wifi
Unfortunately none have the minimum hardware to support either openwrt or dd-wrt. If any supported openwrt or other linux variations, i would connect the wireless interface of the router to the existing WIFI, bring up a new subnet on the wired ports and start a DHCP daemon, and route the traffic there to the wireless interface. Easy enough.
Is there any way to do that via the manufacturer stock firmware?
