I'm confused about the hardware requirement for range extenders. For my purpose, It can be either repeat on the same SSID or a different one.
Does Range Extender have to have two separate WiFi "radios" to work? Can I install OpenWRT on these two old AP/Router and use it as extenders? Is one or the other better since they are both beyond the base 8/64 hardware wise?
for openwrt use only wndr3700 for range extension (r7000's wifi is very bad with FOSS drivers - limited to 54mbps 802.11g - you can try tomato on this one)
