I recently got a 4G/Wifi/ADSL router by TeleWell (model TW-EAV510AC-LTE CAT6). As it lacks a few features I need, I thought I'd check whether there's root access available. Yes, for fun.

Here's what I did, approximately in this order: 1/ 1) Enable telnet access from web UI and log in. No shell option there, mostly just the same stuff one can do via the web UI.

2) RTFM. Nothing. Also, the docs don't tell anything about the architecture.

3) Firmware updates. They come as zips, with a squashed rootfs inside. 2/

Not everything was perfect in 1995, but I think we've lost something on the way. Some remarks:

1) Underlined letters indicate keyboard shortcuts. How handy!

2) Design clearly says: "We are buttons!". It's easy to find the wanted button, because they have some color.

1/3 3) Column titles look like buttons, since they are buttons.

4) The divider resembles window frame, giving a clue of resizability.

5) Always visible scroll bar immediately tells there's more to it, and how much.
