[Solved] Changing Root ssh password in a firmware

You are repeatedly pushing for support for an unofficial version of OpenWRT.

That's what OpenWRT-based means.

Apparently, you're not getting it, so I've asked the moderators to take a look at the thread and make a determination.

You have options...either get support on Totolink (it's their firmware)...or try a tech support or home networking subreddit.
