Cudy m1800 router

have a pair of the above-mentioned routers. Currently they have original firmware and are connected as WiFi extenders to a fiber-optic router/modem.

These can handle openwrt firmware but since am a newbie need some help on how to configure them after I update the firmware. Do I get better range ?

I tried when I bought but was stuck on whats best to configure them and if I should set as router or WiFi extenders.

any help appreciated

Install one,

Try to follow the guide, extender scenaruio is not very demanding on hardware.

OpenWrt does not make mechanical antenna circuit modifucations. Range will be same as with oem firmware, andbon well supported device like yours performance difference will be +/- 10%

Once half way you decide you go to OpenWrt or back to cudy.
