The router was working fine then suddenly stopped connecting to any network. I observe that the date only stopped at December 2012 and won't go beyond that and can't update using the ntp server either. Updating to the latest firmware version dated 2011 didn't help matters. This modem has reached its end of life support with dlink.
After along search for an open source firm ware I came upon your website and from all indication you guys seem to be my best bet for solving this problem of forced obsolescence .I observe you already have a dedicated project page for Ralink/Mediatek devices available here: https://openwrt.org/docs/techref/hardware/soc/soc.mediatek.
My major pain point is how to create a custom rom for dlink Dir-456U router. Please I need a step by step guide. Thanks in advance for you great help
