How can I get wrt610n v2 wireless working with OpenWrt 19.07.07

hi Experts,

I'm having a trouble with wireless drivers for wrt610n v2, since its broadcom wireless b43 doesn't provide its full capabilities, in the previous version eg OpenWrt 15 and 17, I got it to work by install kmod-brcm-wl, wl, wlc, nas, but its not working for the version OpenWrt 19, after following the steps, it only shows b/g wirless for both 2.4ghz and 5ghz

Kindly help me get my wireless to work in its full capability.
