Most folks have probably moved on from using this, but I have still found the Technicolor TG582n router a very capable router, especially for Home network study lab use.
In a later example, I'm going to show a customised reconfiguration I created to support two additional WiFI SSIDs and three internet enabled VLANs.
The following is a collection of things found experimenting with these routers.
Telnet Administrator account name and password required
For any reconfiguration work, you will require knowledge of both of the above for your router.
Depending on the firmware and the ISP that originally supplier the router, this account name may either be the same as the Web GUI, or entirely different. Clues on that and the default password to use may be found by Googling.
The hidden menu system in Telnet
In the telnet window Technicolor have implemented some nicely drawn and descriptive tabular menus as an alternative to the CLI. Just enter the command 'menu' after logging in, and away you go with the cursor keys!
Well, almost. Doing that and drawing the pretty lines may freak out your telnet session.
So if it's not working as here, change these settings in your telnet client program.
| Setting | Windows | Linux |
|---|---|---|
| Windows/Translation - Remote character set | Use Font Encoding | ISO-8859 |
| Terminal/Keyboard Backspace key | Control-H | Control-H |
The above works well in Putty from http://www.chiark.greenend.org.uk/~sgtatham/putty/.
Saving your CLI changes
When configuration changing telnet commands are entered, the router will store just these commands in it's own self managed start-up configuration script stored in volatile memory, lost if the router is powered off.
When you are quite certain of the effectiveness of changes that you have made, you can use the 'saveall' command to write those settings in non-volatile flash memory situated alongside the router's own template configurations and operating firmware, all which will be reloaded after a router physical off-on power cycle.
In non-starting emergencies, holding the reset button for 10s with the power on will restore those settings straight back to pre-script. Here you can either reload a saved configuration, or attempt to recover it all from another hopefully fine memory. Yours :)
A saved configuration? Yes, you can do this from the router GUI, something that I strongly recommend that you do frequently! Here be dragons I warn you!
CLI Reference Guides
A CLI reference guide (in PDF format, and lots of pages!) may be found by Googling for "CLI reference guide R10.2 technicolor".
Several ISP's have made more widely available the earlier reference guide for R8.4 which I have found boringly similar except for commands that configure DNS server routing.
