Anyone has successfully configure their TP-link WDR-4300 with DD-WRT? Mind to share?

Ive tried accordingly to KLsheet /Rizvan guideline but to no avail, the WAN wont connect. Tried Open-WRT and found no GUI and spent hours on offline LUCI instsllation due to no internet , solved with WinSCP and putty.

Downloaded 3rd party Ofmodemandmen open wrt, it works great with both IPTV and Internet, but the WIFI signal worst than original TP firmware no matter how i adjusted the wifi settings.

Generally after brief test on these firmwares wifi strength, DDWRT wifi signal is great, openwrt worst, original good.

So if possible i would like some help from you guys who successfully configured your WDR4300 with DDWRT. thank you

No one? V1.7 version.

Appreciated anyone could help. thank you
