My Net N750 Router is a cheap yet crappy router with dual band(2.4G and 5G). The good part is WD provides its source code to download.
After exploring its source code, I found it provides telnet support.
First, go to http://router_ip/telnet.php to enable it.
Then telnet router_ip
The username and password are hardcoded in the firmware: Alphanetworks/wrgnd13_wd_av
So use it at your own risk!
