Hey guys I need some help. I have the Tp link TD 8951 WD ADSL2+ Modem router. I want to configure a custom firmware (OpenWRT) on it for more advanced QoS settings. I searched about it and found that there is page for the router, but its listed as v1 and mine is v5.1. I wanna know if someone has experience with this model and custom modem firmware. Also, how do I backup the current firmware on the modem router? Thanks
